Input method
floating unbalanced input, each channel mutually isolated (channel independent)
The RTD range (DU100 only) has a common potential (terminal b)
A/D resolution
±20000
A/D integration time
20ms (50Hz), 16.7ms (60Hz), 100ms (10Hz) or auto
(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).)
