Timer Section
Setting range 0.3 to 999 s
Operation
At ON Setting : Displays the time that is counted down from the start
At OFF Setting: Displays the time that has elapsed from the start
Setting resolution 0.1 s: 0.3 to 99.9 s, 1 s: 100 to 999 s
Accuracy 0.3 to 99.9 s: ±50 ms, 100 to 999 s: ±0.5 s
Ramp timer
Setting range 0.1 to 99.9 s, The ramp-up time and ramp-down time can be set individually.
Operation Ramp-up : Using ramp-up time from initial voltage to test voltage to
increase the output voltage gradually
Ramp-down : Using ramp-down time after test time timer to decrease the out-
put voltage from pre-set voltage to 0 V
Both are displayed as time counted down from the set time.
Setting resolution 0.1 s
Accuracy ±50 ms
Delay timer (Withstand-voltage test)
Setting range 0.1 to 99.9 s
Setting resolution 0.1 s
Accuracy ±50 ms
