OPERATING INSTRUCTIONS

CALIBRATE RTD INPUTS

Choose this function to simulate a temperature signal into any instrument requiring an RTD input.

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. Spade lugs are recommended to minimize any contact resistance.

Output temperature is continuously adjustable with the UP/DOWN push-buttons. Zero & Span (or any other values) are available by using the LO and HI "QUIK-CHEKs”.

To Change the RTD type

1)Press the TYPE/ENG UNITS push-button. The words SELECT RTD TYPE and the current selection appear on the display.

2)Press any UP/DOWN push-button until the required type appears on the display.

3)Press the STORE/RESET push-button or wait 5 seconds to store the selection

Note on 4-Wire Connections:

The TechChek 830-KP may be used to calibrate instruments requiring a 4-Wire RTD connection. This connection is valid only when the lead wires included with the 830-KP are used to connect the 830-KP directly to the instrument. Use of longer wires can cause errors in the output setting.

For long 4-Wire cable runs use the 3-Wire connection and add a stacking banana jack (not available from Transmation) to connect a second wire to jack #1. Connect this extra wire to the fourth wire field connection.
