Auto Ramping the Output
Auto ramping gives you 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 you press
L
, the calibrator produces a
continuously repeating 0 % - 100 % - 0 % ramp in your
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.
