Input
Measurement range
Refer to 14.2 on page 14-7.
Measurement interval
Selectable from 0.5, 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60s; max. 500ms/300ch
(with sub-unit connected, filter: OFF, A/D integration period of 20ms or 16.7ms)
A/D integration time
Selectable from 20ms (50Hz), 16.7ms (60Hz), 100ms (10Hz) selectable, or automatically
switched between 50/60Hz. (Except, auto switch does not function on the subunit (DS400/
DS600) of a DC power supply model. Selecting “AUTO” will set the A/D integration time to 20
ms (50 Hz).)
