Fluke 707 ex [11/24] Simulating a transmitter

mA Calibrator

Simulating a Transmitter

When simulating the operation of a transmitter, the

Calibrator regulates the loop current to a known value

selected by you.

A 12 V to 28 V loop supply must be available. Insert the

test leads as shown below.

Auto Ramping the mA Output

Auto ramping allows you to continuously apply a varying

current from the Calibrator to a passive (sourcing) or

active (simulate) loop. Your hands remain free to test the

transmitter’s response.

Press

simultaneously to enter the Auto Ramp

mode and step to a ramp type.

The Calibrator applies or controls a continuously repeating

mA signal over a 0-20 mA or a 4-20 mA span in one of

three ramp types:

Slow (e) 0 % to 100 % to 0 % smooth ramp over 40 sec.

Fast (g) 0 % to 100 % to 0 % smooth ramp over 15 sec.

Step (f) 0 % to 100 % to 0 % stair-step ramp in 25 %

steps, pausing 5 sec at each step.

To exit, press any pushbutton or turn the Calibrator off.
