Auto Ramping the Output
Auto ramping gives the ability to continuously apply a
varying stimulus from the Calibrator to a transmitter, while
your hands remain free to test the response of the
transmitter.
When
L is pressed, the Calibrator produces a
continuously repeating 0 % - 100 % - 0 % ramp in a choice
of three ramp waveforms:
•
E 0 % - 100 % - 0 % 40-second smooth ramp
• P 0 % - 100 % - 0 % 15-second smooth ramp
• N 0 % - 100 % - 0 % Stair-step ramp in 25 %
steps, pausing 5 seconds at each step. Steps are
listed in Table 7.
To exit ramping, press any button.
