3.5.1.2 RANGE IDENTIFICATION CONTACT OPERATION
In all of the range switch modes (MR, RR, AR), the status of the
range identification relay contact corresponding to each Ch (component)
is closed when Range 1 is selected, and open when Range 2 is selected.
Note that even if the range is switched while a hold of measurement
is in place, for instance, by a remote hold contact input or the hold of
measurement value during calibration, the range identification contact
maintains the contact state immediately before the hold. After stop of the
hold, the contact state of the current range is resumed.
