OPERATING INSTRUCTIONS

CALIBRATE PRESSURE TRANSMITTERS

READ PRESSURE AND

P-XMTR mA, P-XMTR %, P-XMTR DP%

Choose this function to simultaneously supply power to a 2-Wire pressure transmitter while supplying the input signal to the transmitter and displaying the 4-20 mA output of the transmitter.

1)Disconnect both the pressure input and output wires from the 2-Wire Transmitter to be calibrated

2)Select the proper module for the pressure range of the process

3)Place the QuikCal 90 Module in the ModPak 91 holder

4)Plug the ModPak cable into the mating connector on the 830-KP

5)Turn the selector knob to PRESSURE

6)The 830-KP will display – – – – – for up to 20 seconds while the module is powered up and verified

7)The 830-KP will display the range of the module for three seconds

8)Press the °C/°F/ZERO push-button to “Zero” the pressure reading

9)Press the DISPLAY/SOURCE/READ push-button until READ or P-XMTR appears in the lower half of the display

10)Press READ/POWER TRANSMITTER to switch between reading milliamps and supply voltage to power the transmitter

11)Carefully make all pressure connections

12)Connect the red POWER lead of the 830-KP (Connector 5) to the plus (+) output of the transmitter and the black POWER lead (Connector 6) to the minus (-)

Use the hand pump or regulated pressure source to adjust the pressure

The TechChek 830-KP supplies a nominal 24 Volts DC at 24 mA to the 2-Wire transmitter. The current output of the transmitter will be accurately displayed by the 830-KP. Calibrate the Transmitter in the usual manner and disconnect the 830-KP.
