Auto Ramping The Ma Output - Fluke 705 Instruction Sheet

Auto Ramping the mA Output

Auto ramping allows you to continuously apply a varying current
stimulus from the calibrator to a passive (sourcing) or active
(simulate) loop while your hands remain free to test the
transmitter's response. The calibrator produces a continuously
repeating ramp in your choice of three waveforms:
E
0 % - 100 % - 0 % 40-second smooth ramp
O
0 % - 100 % - 0 % 15-second smooth ramp
N
0 % - 100 % - 0 % Stair-step ramp in 25 % steps,
pausing 5 seconds at each step.
To exit ramping, press any button or turn the calibrator off.
Using the SpanCheck Function
The SpanCheck™ function checks the zero and span points of a
transmitter in either Source or Simulate mode. To exit the
SpanCheck function, press the SOURCE SIM MEAS key or the
25% key.
