NOTE
When setting calibration timing requirements, bear the following precautions in mind:
(1) If the calibration interval is shorter than the sum of hold (output stabilization) time plus
calibration time, the second calibration start time will conict with the rst 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 conicts with manual calibration or semi-
automatic calibration, the current calibration will not be conducted.
(3) If the calibration time conicts with maintenance service or blow back operations, calibration
will start after completing the maintenance service or blow back operations (see Section
8.2.1, earlier in this manual).
(4) If 000 days, 00 hours are set for the calibration intervals, only the rst 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.
9.2.2 Default Values
When the analyzer is delivered, or if data are initialized, the calibration settings are by default, as
shown in Table 9.1.
