Introduction General Description The Model 130/135 DC/Frequency Calibrators are compact, versatile, functionally styled calibrators. These units are menu driven so technicians can immediately begin using them to their fullest capabilities without extensive training. The Model 130/135 consists of three functional areas: At the top is an alphanumeric liquid crystal display (LCD) for simultaneous indication of input and output readings and operator prompting.
Battery Charging Units are shipped with the internal batteries in an uncharged state. Note: Before using the Model 130/135 calibrator as a portable unit, it is necessary to charge the batteries for a minimum of 14 to 16 hours. The calibrator battery charger is a wall plug-in type (see below) which connects to a jack on the right-hand side of the instrument. Battery operation time is 7-8 hours, typically. CALIBRATOR CHARGER INPUT: 120VAC 60 HZ OUTPUT: 5.
Operation The Model 130/135 DC/Frequency Calibrators are user friendly and menu driven. A first time user can normally start operating the unit with little or no instruction. The following instructions are intended to provide a detailed understanding of the unit. CAUTION: The operation of the calibrator may be impaired if a twoway radio is keyed near the unit. Power On Sequence The calibrator is turned on or off by pressing the ON/OFF key.
This indicates the date in MMDDYY format of the last factory calibration. The example indicates the Model 130/135 was calibrated on August 5, 1993. The next display will be: property of YOUR NAME HERE This shows the name of the owner of the calibrator. The above display shows the default setting as the calibrator is shipped. The name can be changed by selecting “owner” from the setup menu. See page 24 for details on how to change the owner’s name.
Input/Output Selection The Model 130/135 calibrator has a single set of function keys for controlling both input measurements and output simulation. The input measurement section of the calibrator is completely isolated from the output simulation section. To select input or output functions the INPUT and OUTPUT keys are used. The calibrator is in output mode following power on.
Menu Selection The Model 130/135 calibrator has several functions that require additional information once the function has been selected. The additional information is entered by picking from a menu or list of items. For example, when using the Setup function to control the Battery Save function, you must select whether Battery Save is to be enabled or disabled. A detailed description of the menu is provided with each feature that has menu choices.
voltage falls below 4.65 volts, a warning message is displayed is displayed approximately every minute. When the voltage falls below 4.5 volts for 1 minute, the calibrator will turn itself off to prevent damage to the batteries due to possible cell reversal. INC/DEC key functions The INC and DEC keys are multifunction in nature. Their use is explained in detail in each section of the manual where they are used. The following is intended to give an overall understanding of their use.
CE/ZERO Key When the calibrator is in the output mode and you press any of the numeric keys (0-9), the keystrokes will be displayed until you press ENT and the value is accepted by the output function. If you make a keying error, the CE key is used to clear the erroneous entry and allow the correct value to be re-entered. If you press CE a second time before entering any numeric data, the keypad display mode is canceled and the calibrator returns to displaying the actual output simulation value.
Option Key The OPT key is used to activate the external module that is attached to the feature connector of the Model 130/135 calibrator. When the OPT key is pressed for the first time after the calibrator is powered on, the calibrator reads the configuration and calibration data from the attached module. If no valid module is attached, or if the attached module is not supported by the software revision of the calibrator, an error message will appear.
If the module is not capable of operating in the mode requested, an error message will be displayed. The operation of the Pressure Module can be found on page 31. Ramp Key The RAMP key is used to activate the ramp function which is covered in the next section under Output Functions. % Key (Model 135 Only) The % Key allows easy access to the % Error Function.
If no tags have been entered, the display will indicate: ----------------------------------SEQ=01 EMPTY If calibration is complete, the display will indicate “Pass” or “Fail” instead of “Ready”. Pressing the INC/DEC key will allow the user to scroll through the tag list or, enter the sequence number, if known, to go directly to the desired tag. Press SYS to exit the system mode; to continue, press ENT when the desired instrument tag is displayed. The selected tag will be displayed on the top two lines.
If “Review” was selected, the test points would be displayed. INPUT +4.000 +6.000 +8.000 OUTPUT +1.000 +2.000 +3.000 Press the INC/DEC keys to scroll through additional points. Press ENT or CE to return to the previous menu. Clear All Data allows “As Found” and “As Left” data previously stored to be cleared. This option is only allowed if enabled by the Calibration System. If this option is not enabled and is selected, the display will indicate “Option Not Allowed”.
step the calibrator output through the calibration points. Once the desired results are achieved, press AUTO as indicated on the calibrator display. MA VOLTS +4.000 +1.000 ADJUST UNIT AUTO WHEN DONE When “AUTO” is pressed, the calibrator again sets itself at the first cal point and prompts the operator to press AUTO again to start the “As Left” calibration procedure. Pressing CE will take the calibrator back to the Test Complete menu. MA VOLTS +4.000 +1.
If “Done” is selected, the calibrator will prompt “Test Finished” and the operator will be prompted to enter his/her ID number. TEST FINISHED ENTER TECH ID# ??????? The operator will press ENT and then be prompted to indicate “Unit Final Status” and choose “Adjusted”, “Replaced”, or “No Action”. Select the desired menu and press ENT. UNIT FINAL STATUS NO ACTION ADJUSTED REPLACED At this time, the calibrator returns to the beginning mode and a new tag number can be selected for the next calibration.
Note: It is the responsibility of the user to ensure that the Pressure Module being used is the proper range for the calibration being performed. If the instrument being calibrated has a pressure output, no special action is required during the automatic test. The pressure will be monitored as the input function on the calibrator and will be recorded automatically at each calibration point. If the instrument being calibrated has a pressure input, the pressure will have to be generated manually by the user.
When READY is being displayed, the applied pressure is within tolerance. You should wait until the actual pressure readings stabilize and then press the ENT key. The calibrator will then store the readings and step to the next calibration point.
If the input to the instrument cannot be generated by the calibrator, the calibrator will be configured for Manual output. An example might be a magnetic flow meter that requires a manufacturer specific device to simulate a flow into its input. There is an additional feature associated with Manual outputs.
numeric keypad and then press ENT. If the closest you could get to the desired value was 9,950 GPM, you would enter this value and press ENT. It is possible for an instrument to be configured for both Manual input and Manual output. An example might be a glass thermometer that is to be calibrated in a temperature bath. In this case the calibrator will first prompt for the user to set the external output and then prompt the user to enter the external input.
Operator Setup The SETUP key activates the operator setup mode. This allows the operator to preset several convenience features to customize the calibrator for a particular user or application. The SETUP can be activated any time except when the calibrator is displaying a menu. When the SETUP key is pressed, a screen is displayed on the Model 130 showing the first 4 options available. 1-LCD Vu 3-IncDec 2-BatSav 4-Owner If the INC or DEC keys are pressed, additional groups of setup options are displayed.
LCD Vu (Adjust LCD viewing angle) The LCD viewing angle or contrast may be adjusted electronically for optimum viewing under various conditions. There are 8 levels to the contrast adjustment. Press the INC or DEC key to select the adjustment that is optimum for your conditions. Viewing Angle sn 1355 uc 0300 The second line of the viewing angle screen displays additional useful information. The left side displays the serial number of the unit and should agree with the serial number label on the case.
current scale or a user defined calibration point from a predefined list of calibration points. This feature allows the user to program the INC/DEC keys to function in one of two modes: user defined calibration points, or percent of scale. Press the 3 key to program or setup the INC/DEC key functions. The first menu allows you to select Cal Points or Percent. The display will prompt with following: IncDec Key Funct CalPts Percent To setup for the cal points function, highlight CalPts and press ENT.
the last calibration point is entered, the next screen will be: Zero point value ??????? Enter the value in engineering units for the function you will be using that represents the zero value for the calibration points function. After entering the zero point, the next screen will be: Full scale point value ??????? Enter the value in engineering units for the function you will be using that represents the full scale value for the calibration points function.
Example #2: Programming a 3 point calibration for a 1-5 Volt input to a recorder. The calibration points entered would be: cal point #1 cal point #2 cal point #3 zero point full scale point 0 50 100 1 5 (%) (%) (%) (volts) (volts) Utilizing Calibration Points Once calibration points have been enabled from the Setup IncDec key function, they are activated by simply pressing the INC or DEC key after selecting the appropriate output function.
Owner (Enter owner’s name) The Model 130/135 calibrator contains a security feature that allows the owner to enter a name or other identifying number into the calibrator’s non-volatile memory. The owner’s name cannot be changed unless the operator knows the unit’s access code. The access code is unique to each calibrator and is printed on the individual calibration sheet that is shipped with each calibrator.
Press ENT if you are satisfied with the entry, or CE to cancel. If you press CE, the owner’s name will not be changed. If you press ENT, a momentary wait message will appear while the new information is written into the non-volatile memory. Pause (Set pause time for auto CalPts and Ramp) The AUTO key will cause the Calibration Points or Ramp program to repeat continuously without intervention.
MfgTst (Enable manufacturing test routines) (Model 130 Only) This option enables several test routines used in the manufacturing, test, and calibration of the calibrator. These routines are not intended for use in the field. A special factory access code is required to activate these routines. Save (Save setup values in non-volatile RAM) This function allows the setup parameters that have been entered to be saved in non-volatile RAM.
The input functions will return to displaying in engineering when the next input function is selected. Damp (Dampen input readings) This feature allows noisy input signals to be electronically dampened for easier reading. When the feature is enabled, a running average is displayed, rather than the instantaneous value. Input Dampening Disable Enable Select either Enable or Disable using the INC/DEC keys and press the ENT key.
The configuration would be: Input Zero = 4 Input F.S. = 20 Output Zero = 0 Output F.S. = 1500 If a pressure of 1478.7 PSI (98.85% of scale) is applied, the transmitter would be expected to output 98.58% of range or 19.773mA. If the transmitter were outputting only 19.757 (which is a -.1% error), the display would indicate: % error -0.10% % scale +98.58% It is then a simple matter to adjust the transmitter span to achieve a 0% error reading.
Enter output F.S. EngUnits ??????? Exit the Setup menu. The 130 will display the input in % ERR and the output in % Scale on exit from the setup menu. The 135 will now display in the previously selected Engineering Units. To display the % Error press the % Key. Press the % Key again to return to the Engineering Unit display. Once the calibrator is turned off, all % Error setups are lost.
Input Functions Input functions are selected by pressing any of the function keys while the calibrator is in input mode. Functions available on the Model 130/135 are Volts, Millivolts, Milliamps, Frequency, and Totalize. Input mode is selected by pressing the INPUT key. The calibrator remains in input mode until the OUTPUT key is pressed. The cursor position on the display provides an indication of input or output mode.
and display in Hertz. The frequency measurement will be displayed with the maximum resolution. If the input frequency is below 5 Hz, the frequency display is blank. Totalize To activate the Totalize function, press the TOT key. The Totalize function allows the calibrator to function as a counter to measure very slow digital outputs. The Totalize function has two possible states: HOLDING and COUNTING. When the Totalize function is first selected, it will be in the Holding state.
Pressure Module (Optional) The Pressure Module allows a Model 130/135 calibrator to make the precise pressure measurements required for calibrating field pressure instruments. The Pressure Module is a measurement only device. The source of pressure must be supplied externally, usually by a hand pump. Electrical Connections The Module attaches to the calibrator’s feature connector, located at the bottom of the unit. The connector is keyed to prevent improper installation.
When the OPT key is pressed for the first after the calibrator is powered on, the calibrator reads the configuration and calibration data from the Pressure Module. The first time the OPT key is pressed, a series of messages is displayed listing the configuration of the Pressure Module. The first display is: Pressure Module PSIG 30 The top line shows that a Pressure Module is attached and the second line gives the range. The above example is for a 30 PSIG Pressure Module. The second display is: Serial No.
Software versions prior to 03.35 use the 4°C conversion temperature. The factors used by the Pressure Module to convert from PSI to other engineering units are listed below. 2.036 51.715 6.8948 68.948 0.068948 27.681 27.707 27.730 70.310 70.376 70.433 “Hg mmHg KPascals milliBars Bars “H2O “H2O “H2O cmH2O cmH2O cmH2O @0°C @0°C @4°C @60°F @20°C @4°C @60°F @20°C When the OPT key is pressed a subsequent time(s), the calibrator checks the ID and serial number of the attached module.
alternating readings between pressure and milliamps. This may cause a barely perceptible slowing of response time of the readings. If the simultaneously display of pressure and milliamps readings are not required, the Pressure Module should be operated as an input function for quickest response times. If pressure measurements are not being made, the calibrator should be turned off and the pressure module disconnected.
Enter the local barometric pressure in the engineering units that are selected, and press ENT. The absolute pressure readings are then compensated by using the entered value as the reference pressure. There may be a slight drift of the zero reading during the first few minutes of operation after power is first applied to the Pressure Module. The user should recheck the zero by venting any pressure and observing the reading.
The pressure adapter module receives power and commands from the calibrator’s output section and the pressure readings are made through the calibrator’s input section. As a result the calibrator loses its input to output isolation any time the pressure module is plugged into the feature connector. This is not a problem as far as pressure measurements are concerned.
Trip Detect The trip detect feature is used in conjunction with the Ramp Function. Trip detect is a feature to aid in calibrating trip point alarms under simulated operating conditions. The ramp output of the calibrator simulates the changing process as an input to the alarm circuit. The contact output of the alarm circuit connects back to the voltage input of the calibrator. The trip detect feature can utilize the volts input terminals.
To test the dead band of an alarm, first initiate a positive going ramp using the INC key and record the trip point. Next initiate a negative going ramp using the DEC key and record the trip point again. The difference in the two recorded trip point values represents the dead band of the alarm.
Input Reading in Percent of Scale This feature allows the input measurements to be displayed as a percent of scale rather than in engineering units. This allows error calculations in percent to be quickly calculated. The feature is accessed through the Setup option InpRdg, and is normally utilized with output Calibration Points which are also programmed in percent of scale. An example would be the testing of a turbine meter transmitter.
Output Functions Output functions are selected by pressing any of the function keys while the calibrator is in output mode. Output functions available on the Model 130/135 are Volts, Millivolts, Milliamps, and Frequency. Output mode is selected by pressing the OUTPUT key. The calibrator remains in output mode until the INPUT key is pressed. The cursor position on the display provides an indication of input or output mode.
achieved at all times. The internal microprocessor will automatically correct for any drift due to temperature or battery change. The millivolts output function is identical to the volt function except that the value is entered and displayed in millivolts. Milliamps To output Milliamps, press the MA key when the calibrator is in the Output mode. The calibrator will prompt for the value desired. mAMPS ?????? Enter the desired current in milliamps and press ENT.
Enter the desired value between .25 V and 10.0 V and press ENT. The calibrator will set the output amplitude and then prompt for the frequency value. Hertz ?????? Enter the desired value between 0.01 Hz and 100,000 Hz and press ENT. If an improper or out of range value is entered, the calibrator will display an error message. Error messages and their meanings are listed on pages 57 and 58. If the value is within the operating limits, the calibrator will set the output to the requested value.
Ramp Function The ramp function provides an output ramp with adjustable rate and amplitude for volts, millivolts, and milliamps. When the RAMP key is pressed, the following screen will be seen: Starting value ?????? Enter the starting value for the ramp in engineering units for the function you are using and press ENT. The next screen will be: Ending value ?????? Enter the ending value for the ramp in engineering units for the function you are using and press ENT.
DEC key to initiate the ramp from the ending value. If the trip detect is enabled, you must press the INC or DEC key twice. See the trip detect description on page 38 for more information. While the ramp is slewing, the display will show: Slewing xxxxxx The instantaneous value will be updating in the display. You will notice periodic pauses in the display as the calibrator does internal calibration cycles. This does not affect the output ramp and only causes a pause in the displayed value.
Loop Power Supply (Optional) The Loop Power Supply (LPS) is an option that provides 24 VDC to power a device under test. The LPS is shipped with the batteries in an uncharged state. Note: Before using the LPS as a portable unit, it is necessary to charge the batteries for a minimum of 14 to 16 hours. The battery charger for the LPS is different from the one supplied with the Model 130/135 and 230/235 calibrators. The LPS contains eight (8) AA Ni-Cd batteries that provide power to a DC to DC converter.
puts the calibrator in series with the 4 to 20 milliamp loop. Plug the test leads provided with the calibrator into the jacks marked “Loop Power” on the LPS and connect them to the instrument under test, with proper polarity (+ to + / - to -). The batteries of the LPS can be checked by plugging the same special cable provided with the LPS from the plug marked “Battery Charger” on the LPS, to the V input jacks on the calibrator.
Application Notes Use of Transmitter Simulator With Power Source The purpose of this function is to simulate a 2-wire transmitter connected in a loop. In order for this function to operate correctly, the process control loop must have a power source in it. Connect the calibrator as shown below.
Use of Transmitter Simulator Without Separate Power Source The Model 130/135 Calibrator can be used to calibrate 2 wire, 4 to 20 mA transmitters without the need to use a separate DC power supply. This is useful for bench calibration during construction check-out prior to startup. Of course, if the loop is complete and energized, you would not use this technique but would calibrate as usual. Figure 2 shows the proper hookup.
Turbine Meter Calibration Using the Totalize Function For flow transmitters designed for very low flow levels, it is frequently more convenient to calibrate using the Totalize function. This involves counting the number of pulses from the turbine when a known volume of liquid is passed through it. 1. Connect the frequency or pulse output leads of the flow transmitter to the frequency input terminals of the Model 130/135 calibrator as shown in Figure 4. 2.

Calibration of an Alarm Using Ramp and Trip Detect This example describes calibration of a current input alarm circuit. The calibrator should be connected as shown in Figure 5. The connection to the alarm contacts can be made across either the NO or NC contacts since the calibrator is simply looking for a change of state. This example assumes that the alarm should trip when the current exceeds 12 mA and reset when the current falls below 11 mA.
7. Press the DEC key to ready the ramp at its ending (14 mA) value. 8. Press the Dec key again to start the Ramp. 9. Wait for the alarm to reset. The input display will again display “Tripped” and the Ramp will be stopped. 10. If the alarm release point is not within the desired accuracy, adjust it and repeat from step 7. Alarm NO NC INPUT + Power Supply - + 30V Max External 10K-100K resistor required to provide Stable reading when contacts are open.
Calibration of mV to Current Converters This example assumes a 10 to 50 mV input and a 4 to 20 mA output. 1. Connect as shown in Figure 3. 2. Select mA input. 3. Select mV output. 4. Enter 10 mV and adjust converter zero for 4 mA output. 5. Enter 50 mV and adjust converter span for 20 mA output. 6. Repeat steps 4 and 5 until both zero and span are within desired tolerance.

Error Messages Entered value is out of range The value entered is outside of the allowable range for the current output function. Check the specifications for the function being used to determine the allowable range of values. Expecting ENTER CE or INC/DEC The only keystrokes that are acceptable at this time are the ENTER, CE, INC or DEC. Expecting ENTER or CE/CANCEL The only keystrokes that are acceptable at this time are the ENTER or CE (interpreted as Cancel).
No external module present You pressed the OPT key and there is no external module attached to the calibrator. If there is a module attached, turn the calibrator off and back on and attempt the operation again. If the error persists the module is probably defective. No mode change in MENU/SETUP You have pressed the INPUT or OUTPUT key while a menu is active or in Setup mode. You must complete the menu or setup sequence before changing modes.
Service Information Return for Calibration, Recertification or Repair It is recommended that each calibrator be re-calibrated and/or recertified on an annual basis, and pressure modules re-calibrated and/or recertified on a 6 month basis, against precision standards that are traceable to the National Institute of Standards and Technology. All returns should include a statement of the work requested and the exact address to which the unit should be returned.
Fuse Testing The calibrator employs fuses to protect the outputs and inputs in the event the calibrator is improperly connected to external circuitry. It is necessary to remove the covers in order to access the fuse panel. The following tests should be performed BEFORE removing the covers to determine if a fuse is actually blown. Fuse Type/ Location Input/ Output Fuse No. F1 Function Test mA Input Connect an ohmmeter across the input milliamps terminals. The resistance should be approximately 5 ohms.
Fuse Type/ Location Input/ Output Fuse No. Model 130 F2 Model 135 F3 Top PCB 130/135 Function mA Output Short the milliamps output terminals and attempt to output 10mA. If the output reads Open, the fuse may be blown. Measure from the mA positive (red) terminal to the volts out negative (black) terminal. If you measure 13-15 V the fuse is OK.
Fuse Replacement Should it become necessary to change a fuse, take the following steps: Read the following procedure fully and carefully before opening the case for fuse replacement. Damage to the keypad and/or keypad connector can occur if you do not follow these instructions. 1. Turn the calibrator OFF. 2. Remove the 4 screws located at the corners on the bottom of the unit. 3.
