Transmitter Mode - Fluke 741B User Manual

Transmitter Mode

You can set up the calibrator so that a varying input
(MEASURE) controls the output (SOURCE), like a
transmitter. This is called "Transmitter mode." In
Transmitter mode, the calibrator can be temporarily
used as a substitute for a defective or suspect
transmitter.
Do not use Transmitter mode in any
environment that requires intrinsic safe
equipment and practices.
Caution
Transmitter mode is for diagnostic
purposes only. Use a fresh battery. Do
not use the calibrator in place of a
transmitter for extended periods.
Warning
Documenting Process Calibrator
To set up the calibrator to emulate a transmitter,
proceed as follows:
1. Disconnect the control bus wires from the
transmitter output (loop current or dc V control
signal).
2. Connect test leads from the appropriate
calibrator SOURCE jacks to the control wires in
place of the transmitter.
3. Disconnect the process input (e.g.,
thermocouple) from the transmitter.
4. Connect the process input to the appropriate
calibrator MEASURE jacks or input connector.
5. If necessary, press
6. Press the appropriate function key for the
process input.
