Procedure

Turn off the instrument power.

Install the instrument into the pipe or a test stand where it can be calibrated. Start the process media flowing at a
normal rate. Cool the process media to the lowest temperature in the expected operating range.

Disconnect the wires leading to the sensing element (ACT, REF, COM HTR, HTR). Removal of the terminal
strip from the enclosure may be necessary for access to the wires.

Connect the DMM's and the power supply to the sensing element as shown in Figure D-2.

Set the power supply voltage to the proper voltage as shown in Table D-1. Turn on the power supply and check
the voltage setting.
