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.

Automatically switched from second range
Remote:
Voltage contact input
signal when remote range switch input
is received.
When the contact input terminals for
each component are input voltage, the
to the second range when the terminals
are open.
* These switch range value are settable between
range values).
