Temporisation

PERMANENT mode The rise duration set is active. The output voltage rises to the setpoint. Test stops if there is a

fault or if pressing the red button on the front panel.

AUTO mode Test runs in 3 sequences : linear raise up to set voltage (Ramp Up), set output voltage remains

applied (Dwell), progressive descent to 0V (Fall)

Ramp Up - Dwell - Fall duration 0,1 à 9999,0 s by steps of 0,1 s

Accuracy +/- 20 msec
