• When the calibration mode is in automatic:
In addition to the above hold (output stabilization) time and calibration time, set the interval,
start date, and start time.
Interval means the calibration intervals ranging from 000 days, 00 hours to 255 days, 23
hours.
Set the first calibration day and the start-calibration time to the start date and start time
respectively. After the first calibration is carried out, the next calibration will be executed
according to the preset calibration intervals.

Setting
When setting calibration timing requirements, bear the following precautions in mind:
NOTE
(1) If the calibration interval is shorter than the sum of hold (output stabilization) time plus
calibration time, the second calibration start time will conflict with the first calibration. In such
a case, the second calibration will not be conducted. (When both zero and span calibrations
are to be performed, the calibration time is double that required for a single (zero or span)
calibration.)
(2) For the same reason, if the calibration start time conflicts with manual calibration or semi-
automatic calibration, the current calibration will not be conducted.
(3) If the calibration time conflicts with maintenance service operation, calibration will start after
completing the maintenance service operation (see Section 8.2.1, earlier in this manual).
(4) If 000 days, 00 hours are set for the calibration intervals, only the first calibration will be
conducted; a second or later calibration will not be conducted.
(5) If a past date is set to the calibration start day, no calibration will be conducted.
