Figure 3-8: Example Auto Zero Calibration
Note: When an auto zero calibration starts, the measurement
screen automatically appears.
Any operation other than “Stop Auto Zero Calibration” (see
Section 3.5.4.5 is not permitted during auto calibration.
“Stop Auto Zero Calibration” cannot be performed when
the key lock is ON.
To cancel auto zero calibration, set the key lock to OFF
and then execute “Stop Auto zero Calibration”. 0 If the auto
calibration period and auto zero calibration period have
overlapped, the auto calibration is retained, ignoring the
auto zero calibration of that period.
If the auto calibration and the auto zero calibration periods
overlap, the auto calibration setting is retained. The
instrument ignores the auto zero calibration period.
When the hold setting is set to ON, the hold time of auto
calibration contact and measurement value output signal is
extended after calibration for gas replacement time.
Turn on the power again after it is turned off (including the
case of power failure) at the time set as the next start time
in auto zero calibration, and then repeat it in the set cycle.
