2. Standard Functions
Output signal holding:
Output signals are held unchanged during
manual and auto calibrations by activation
of holding (turning “ON” its setting).
The values held are those just before
start calibration mode or setting value.
Usage is selectable.
Indication of instantaneous values will
not be held.
Switch ranges: The switch ranges function is available in
manual, auto, and remote modes. Only
preset switch method is effective.
Manual: Allows range to switch by key operation.
