9.2.1.6 Setting
When setting calibration timing requirements, bear the following precautions in mind:
CAUTION
(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 8.3.1, 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.
