Simulating A Transmitter; Auto Ramping The Ma Output - Fluke 707Ex User Manual

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 +
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 ( ) 0 % to 100 % to 0 % smooth ramp over 40 sec.
Fast ( ) 0 % to 100 % to 0 % smooth ramp over 15 sec.
Step ( ) 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.
