OPERATING INSTRUCTIONS

CALIBRATE TRANSMITTERS

ANY SOURCE FUNCTION AND

READ mA, READ %, READ DP%

Choose this function to supply the input signal to the transmitter and displaying the 4-20 mA output of the transmitter (used with 4- Wire Transmitters).

ANY SOURCE FUNCTION AND

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

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

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

2)Choose a function of the 830-KP that matches the input of the transmitter (T/C, RTD, Freq, etc.). Select the proper type, range and temperature scale if applicable.

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

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

5)Connect the output of the 830-KP to the signal input of the trans- mitter (using the 1, 2 & 4 connectors or the T/C connector on the 830-KP)

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

(Connector 6) to the minus (-)

CALIBRATE 4-WIRE TRANSMITTERS

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. This function operates in all three output positions (HI, SET & LO). Press the HI & LO Quik-Cheks to recall stored outputs.

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.
