CAUTION
When setting calibration timing requirements, bear the following precautions in mind:
(1) If the calibration interval is shorter than the sum of 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 or blowback operations,
calibration will start after completing the maintenance service or blowback opera-
tions (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 date, no calibration will be conducted.
