In case where auto zero calibration is carried out at the above setting.
Gas replacement time after calibration is the same as
the flow time.

Setting range
When an auto zero calibration starts, the measurement screen automatically appears.
During auto zero calibration, any key operation is not permitted other than operations such
as key lock ON/OFF and “Forced stop of auto zero calibration” (see Section 6.5.2.2).
When the key lock is set at ON, even the “Forced stop of auto zero calibration” cannot be
performed. To cancel auto zero calibration forcedly, set the key lock to OFF and then
execute “Forced stop of auto zero calibration”.
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.
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.
When the hold setting is set to ON, the hold time of auto calibration contact and
measurement value output signal are extended after calibration for gas replacement time.
