2- Input Modules Overview The BetaGauge II is a two-channel, multi-range instrument. You can change ranges simply by plugging in new input modules, and you may install or remove modules even while the unit is powered up. The calibrator automatically recognizes the module types and displays the appropriate units.
Installing and Removing Modules You may insert or remove a module while the calibrator is on or off. If the calibrator is on, the module will selfinitialize within 3 seconds and a reading will display on the LCD. When facing the calibrator, the left module bay corresponds to Channel 1, and the right module bay corresponds to Channel 2. CAUTION: Use care when handling modules. It is recommended that you store unused modules in the carrying case supplied with the calibrator.
Removal Procedure To remove a module from the BetaGauge II calibrator, place one hand on the calibrator and use the other hand to firmly grasp the module and pull directly out from the calibrator. NOTE: If a BetaPort–P pressure module is removed or disconnected while the BetaGauge II is reading pressure units, the display will show an invalid pressure reading.
Procedure Use the following procedure to connect the BetaPort– DC electrical module to a field device: NOTE: Install the module in the calibrator prior to connecting the module to field devices. 1. Insert the common pin (marked by a tab) on the dual banana connector into the negative (black) terminal marked with a "–" on the module. 2. Insert the opposite pin into the positive (red) terminal marked with a "+" on the side labeled "V" for voltage measurement and "mA" for milliamp measurement.
BetaPort–P Pressure Modules The BetaPort– P pressure modules are fitted with 316 S.S. 1/8" FNPT connections. A variety of connectors and adapters are available from third parties to allow connection to any type of field device. It is recommended that you use an appropriate pipe thread seal (such as Teflon tape) with any connector. This improves thread sealing and reduces the likelihood of galling the threads.
CAUTION: Failure to use a backup wrench may damage the calibrator and/or the module and will void the product warranty. Do not use the pressure connections to support the calibrator. Pressure Module Media Compatibility BetaPort–P pressure modules consist of two basic types: non-isolated isolated Consult the calibrator specifications (Appendix B) for details about which modules are isolated and which are non-isolated.
Pressure Module Safety Always use good safety practices when working with high pressures. Although liquids are considered noncompressible, dissolved and trapped gases can exist in the system and can store significant energy when compressed under high pressure. Always use good quality fittings that are rated for the pressures you are using and always use safety glasses or goggles. Overpressure Protection The sensors used in BetaPort–P pressure modules have excellent overpressure specifications.

The Test Setup screen is divided into five sections. These sections are described below in the order that they appear on the screen from top to bottom: Tag Number/Area. The current tag number and area is listed in the top portion of the screen. Low/High Test Point Values. This section lists the lowest and highest test point values of the selected tag. These values include the minimum to maximum ranges for the field instrument’s input and output measurements.
Choosing Appropriate Modules In choosing the appropriate modules for the test point values of the current tag, you can use the following examples as guidelines. Example 1: Over-Pressure Protection For those tags that require a pressure module, the BetaGauge II will accept a 5000 PSI module to perform a 5 PSI test. However, if you install a 5 PSI module for a test that requires 200 inches of water column, the status message will read Wrong Module(s).
Accessing the Zero Screen When the Modules Correct status message appears on the Test Setup screen, you can access the Zero screen where you can zero the display readings of the installed modules. To access the Zero screen, press the function key corresponding to the Ready menu item on the Test Setup screen. The Zero screen shows live input displays of the two modules currently installed. A sample is shown below: Tag 2: BG2 TAGS Tag 2 CH1 0.0008 Inst. OUT mA DC CH2 0.1103 Inst.
System Prompt. This section first prompts you to zero the display for channel 1, then follows with channel 2. Menu Items. The menu items (Ready and Zero) that appear at the bottom of the screen allow you to zero the display for the current channel or bypass the zeroing operation for the current channel. Zeroing the Display Readings From the Zero screen, use the following procedure to zero the display readings of the installed modules prior to starting a test.
2. After you select the Zero or Ready menu item for channel 1, the calibrator prompts you to zero channel 2. Repeat step 1 to zero the display for channel 2 or bypass the option. 3. After you select the Zero or Ready menu item in step 2, the calibrator displays the Execute screen. Refer to the paragraphs below for information concerning the Execute screen. NOTE: You can exit the SYS mode by pressing the CLR key once to return to the Tag Status screen, then once again to return to the Setup menu.
Execute Screen Description The Execute screen is divided into six sections. These sections are described below in the order that they appear on the screen from top to bottom: Tag Number/Area. The current tag number and area is listed in the top portion of the screen. NOTE: When using an instrument maintenance software package, all tags must be assigned to an area. Refer to your instrument maintenance software manual for more information. Input/Output Types.
Tag Calibration Before you begin the calibration process, it is important to know the following information: You must have already specified the tag number you want to calibrate on the Tag Status screen in the Main level. (In other words, you cannot specify a tag number from the Execute screen.) You can cancel the calibration test at any time during the process by pressing the CLR key to return to the Tag Status screen. To perform tag calibration, do the following: 1.
3. When the applied field instrument input value comes within the allowed pressure tolerance, the BetaGauge II beeps. When you hear the beep, press the ENTER key. (The system will not accept the ENTER key until you hear the beep.) NOTE: If the actual field instrument output is within the allowed error tolerance of the calculated ideal output, the BetaGauge II will change the calibration status for that test point from Un to C.
Accessing the Post-Test Status Screen After you have calibrated the last test point for the current tag, the BetaGauge II displays the Post-Test Status screen. A sample is shown below: Tag 2: BG2 TAGS Tag 2 Inst. OUT: mA Inst. IN: PSI Status: PASS Time: 11:23:59 Date: 10/07/96 Error Tol: 0.0500 Alert Tol: 999999 Next: As Left 1 Adj. Instr.
Specifying Post-Test Status Information NOTE: You must answer the post-test status prompts. If you press the CLR key prior to answering the post-test prompts, all calibration results will be lost. To specify post-test status information, do the following; 1.

A-Battery Care/Maintenance Overview Before handling the batteries used with the BetaGauge II, read the following danger, warning, and caution statements. DANGER! Failure to carefully observe the following procedures and precautions can result in battery leakage, heat generation, bursting, and serious personal injury. Never dispose of a battery pack in a fire or expose a battery pack to high temperatures.
WARNING! Do not apply water, seawater, or other oxidizing agents to the battery pack, as this can cause rust and heat generation and can result in the battery pack bursting. Never use the battery pack if it is leaking, deformed, discolored, damaged, or is different from its original condition. External damage to the battery pack can be a sign of a malfunction. When the usage time for the battery pack becomes extremely short after charging, its operating life has ended and it should be replaced.
CAUTION! Do not strike or drop the battery pack. Sharp impacts or concussions to the battery pack may result in leakage, heat generation, and bursting. Always follow the specified charging temperature ranges on the battery pack.
Battery Packs The BetaGauge II uses rechargeable nickel–cadmium (NiCd) batteries that have high power-to-size-andweight ratios. If properly maintained and cared for, they will provide years of excellent service. However, NiCd batteries are susceptible to damage under the following conditions: Heat. Protect the batteries from prolonged exposure to extremely hot temperatures. Cold. Protect the batteries from prolonged exposure to extremely cold temperatures.
Guidelines for Using Batteries It is recommended that you use the following guidelines when using batteries: When installing or removing a battery pack, do not touch or bend the battery connection terminals on the calibrator. When installing or removing a battery pack, do not short the terminals on the back of the battery. Doing so will damage the battery pack and may cause bodily injury. Dispose of unusable batteries as specified by local regulations.
Removing a Battery Pack Use the following procedure to remove a battery pack: 1. Before removing a battery pack, turn off the calibrator and disconnect the charger. 2. Loosen the two captive screws on the back of the battery pack. 3. Pull the top of the battery pack away from the calibrator, lifting up and out.
Viewing the Battery Voltage There are two methods for viewing the current battery voltage: Approximate reading. A battery symbol, in the upper right corner of the LCD display, shows the approximate battery voltage. The highlighted (or dark) portion of the battery indicates the amount of available voltage.
NOTE: The scale is 6.5 Volts when full and 5.5 Volts when empty. Nominal full charge is 7.00 Volts, and the calibrator shuts off at 5.3 Volts. The message Low Battery flashes when the battery voltage drops below 5.5 Volts. Exact reading. You can view the exact voltage of the current battery by pressing the BAT key on the keypad. When you press the BAT key, the battery voltage reading replaces the battery symbol in the upper right portion of the LCD.
Quick Charge Pack (optional) The quick charge battery pack is designed with special discharge circuitry that can cycle the battery to a discharged state before recharging. This cycling prevents battery failure due to the memory effect of NiCd batteries. The quick charge battery pack requires the high capacity quick charger for proper charging. The charger for the quick charge battery pack is a high capacity charger that can fully charge the battery pack from a fully discharged state within 90 minutes.
The status of the quick charge battery pack charge cycle is indicated by the LED indicator on the battery pack: Steady On indicates fast charging. Rapid Flash indicates charged. Slow Flash indicates discharging. Off indicates that the cycle is disabled or the battery pack is not receiving power from the AC adapter. NOTE: The charger for the quick charge battery pack is different from the standard charger. The two should not be used interchangeably.
