6.2 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

_

, the calibrator produces a continuously repeating 0 % -

100 % - 0 % ramp in your choice of three ramp waveforms:
The calibrator will produce a continuous, repeated slope output ranging from 0% -
100% -0%when

is pressed. Three slope wave shapes are available for your

selection:

0%-100%-0%

40-second smooth ramp

0%-100%-0%

15-second smooth ramp

0%-100%-0%

25% stepping ramp. Each step remains 5 seconds.

Exit the slop output function, please press any key.

6.3 Factory Reset

Factory reset consists of the following default setting:

The working status recovers to the voltage measurement.

Automatic shutdown time is reset to be 30 min, which is effective.

LCD backlight brightness is set to be 60%.

Output range is recovered to be factory default.
Start the calibrator and press

until the buzzer works and the recovery of

factory default will enter working mode when the recovery is completed.
