Setting of single calibration of all or each range:
This setting operation is used for calibration of all or each range during zero/span calibration.
Carry out the setting as follows.

: The calibration is valid only for the selected range,
and zero and span calibration can be made indepen-
dently for each range.
: By conducting zero and span calibration for one
range, the calibration will be done automatically for
the other ranges as well.
Note 3: S.CAL “1” is interlocked with the range ratio
calibrated by “0” on each range.
Note 4: When a 1-range meter is used, be sure to set
S.CAL to “0”. If “1” is set, the result is the
same as “0”.
Press the ENT key when the selection is finished.
