BAR, mBar, Atm, Kgf plus torr, inches and mm of mercury or water at a variety of temperatures. Characterized modules for laboratory accuracy in the shop, control room or field. GENERAL TURN-ON Each time you turn on the TechChek 830-KP it runs through a self check then returns to the most recently selected settings. Voltage Calibration Calibrate all your DC millivolt and voltage instrumentation. Source from 0.00 to 110.00 mV and 0.00 to 10.25 V. Read up to 110.00 mV, 11.00 V and 200.0 VDC.

OPERATING INSTRUCTIONS GENERAL FIELD & BENCH USE TechChek 830-KP comes with a carrying case and a built-in tilt stand/hanger. The 830-KP is held securely in the case by VELCRO® for use with the carrying case open. The carrying case also has a snapon belt loop which can be looped around a pipe or rail. The tilt stand is easily raised by pulling the stand until it locks into place. The stand can also be reversed for use as a hanger to suspend the 830-KP.

OPERATING INSTRUCTIONS OPERATING INSTRUCTIONS SOURCE MODE Select source by pressing the DISPLAY/SOURCE/READ pushbutton until the word SOURCE appears on the LCD display. To change the output value, press the UP or DOWN key for each digit. To ramp the output press and hold any UP or DOWN pushbutton. The display will continue to change in increments corresponding to the digit being changed and will automatically carry up and down until the limits of the range are reached.

OPERATING INSTRUCTIONS OPERATING INSTRUCTIONS SIMULATE 2-WIRE TRANSMITTERS 2-WIRE mA, 2-WIRE % (Percent of 4 to 20 mA) 2-WIRE DP % Choose this function to simulate a 2-Wire Transmitter output from 1.00 to 24.00 milliamps. Operates in loops with power supply voltages from 3 to 45 VDC. CALIBRATE VOLTAGE INPUTS V, mV Choose this function to provide an output from 0.00 mV to 110.00 mV and from 0.00 to 10.25 VDC. Current compliance up to 20 mA to provide the driving power to your voltage receivers.

OPERATING INSTRUCTIONS OPERATING INSTRUCTIONS CHECK 1-5 VOLT INPUTS WITHOUT DISCONNECTING WIRES Most 1-5 Volt receivers in 4-20mA loops have a 250 Ohm resistor across the input of the receiver. This resistor may be mounted internally or externally. TechChek 830-KP is connected directly across the input of the 1-5 Volt receiver without disconnecting any field wiring. This saves a great deal of time when a large number of voltage receivers, such as chart recorders or computer systems, require calibration.

OPERATING INSTRUCTIONS OPERATING INSTRUCTIONS CALIBRATE THERMOCOUPLE INPUTS Choose this function to simulate a thermocouple signal into any instrument requiring a thermocouple input. The output of the 830KP is automatically cold junction compensated. CALIBRATE RESISTANCE INPUTS Choose this function to simulate a resistance into a variety of instruments. 1) Disconnect the thermocouple from the instrument being calibrated.
PAGE 10
OPERATING INSTRUCTIONS OPERATING INSTRUCTIONS CALIBRATE RTD INPUTS Choose this function to simulate a temperature signal into any instrument requiring an RTD input. CALIBRATE RTD INPUTS 1) Disconnect the RTD from the instrument being calibrated. 2) Press the T/C/RTD/Ω pushbutton until any RTD type (Pt, Ni or Cu) appears on the display. 3) Press the DISPLAY/SOURCE/READ push-button until SOURCE and any RTD TYPE appear on the display 4) Connect using 2 or 3 wires as in the diagrams on the opposite page.
PAGE 11
OPERATING INSTRUCTIONS OPERATING INSTRUCTIONS CALIBRATE FREQUENCY INPUTS Choose this function to provide pulses into frequency measuring instruments. The 830-KP output is a zero crossing square wave from -1V to +5V amplitude. Available ranges are from 0.01 to 10.00 kHz, 1 to 1000 Hz and from 1 to 1000 CPM (Counts-PerMinute). CPM is used to simulate extremely slow frequency signals with greater resolution. For example, 10 Hz is equivalent to 600 CPM. To convert from CPM to Hz Divide by 60.
PAGE 12
OPERATING INSTRUCTIONS READ MILLIAMP OUTPUTS mA, mA % (Percent of 4 to 20 mA), DP% (DP Flow) Choose this function to measure from 0.00 to +24.00 milliamps. 1) Open the current loop at any convenient point along the signal path 2) Press the MILLIAMP/V push-button until mA or mA and % appear on the display 3) Press the DISPLAY/SOURCE/READ push-button until READ appears on the display 4) Press the mA/%/% DP FLOW push-button to display mA, % 4-20 or % DP Flow.
PAGE 13
OPERATING INSTRUCTIONS OPERATING INSTRUCTIONS READ AC VOLTAGES Choose this function to measure from 0.0 to 250.0 V True RMS. MEASURE THERMOCOUPLE SENSORS Choose this function to read a thermocouple. The input of the TechChek 830-KP is automatically cold junction compensated.
PAGE 14
OPERATING INSTRUCTIONS OPERATING INSTRUCTIONS READ RESISTANCE CHECK CONTINUITY Choose this function to check continuity. A tone will sound and a sound symbol will appear on the display when the resistance between the leads is less than 100 Ohms. 1) Plug the leads into the TechChek 830-KP as shown below. 2) Press the T/C/RTD/Ω pushbutton until the Ω symbol appears on the display.
PAGE 15
OPERATING INSTRUCTIONS OPERATING INSTRUCTIONS MEASURE RTD SENSORS Choose this function to read an RTD. Three wires must be use for both 2 and three wire RTDs. MEASURE RTD SENSORS 1) Disconnect the RTD from the instrument being calibrated. 2) Press the T/C/RTD/Ω pushbutton until any RTD type (Pt, Ni or Cu) appears on the display. 3) Press the DISPLAY/SOURCE/READ push-button until SOURCE and any RTD TYPE appear on the display 4) Connect using 3 wires as in the diagrams on the opposite page.
PAGE 16
OPERATING INSTRUCTIONS OPERATING INSTRUCTIONS COUNT FREQUENCIES Choose this function to use the 830-KP as a frequency counter. Available ranges are from 0.01 to 15.00 kHz, 1 to 1500 Hz and from 1 to 1500 CPM (Counts-Per-Minute). To measure waveforms with amplitudes between 1 V and 10.25 V RMS use the low level inputs. Use the high voltage connection to read waveforms with amplitudes from 10.25 to 250.
