Style Number S1
Input method
floating unbalanced input, each channel mutually isolated (channel independent)
The RTD range has a common potential (terminal b)
A/D resolution
±20000
A/D integration time
20ms (50Hz), 16.7ms (60Hz), 100ms (10Hz) or auto
However, AUTO does not function if the instrument is the stand-alone DC power supply model,
or the subunit (DS400/DS600) of the DC power supply model. (Selecting “AUTO” will set the
A/D integration time to 20 ms (50 Hz)).
