The auto calibration status contact output is closed while auto zero calibration is in progress (hold
extension time by the length of time the same as gas replacement time included if the hold setting is set to
ON), and open in other cases.
Cycle : 1 to 99 hours or 1 to 40 days (initial value 7days)
Flow Time : 60 to 599 sec (initial value 300sec)
Setting range
(An example of “CH1: through CH3: enable”, as given in Item 6.2.5 “Auto Calibration

Example
In case where auto zero calibration is carried out at the above setting.
Start Time SUN 12:00
Cycle 12 hour
Flow Time 300 sec
ON/OFF ON
Setting range
When an auto zero calibration starts, the measurement screen automatically appears.
Any key operation other than key lock ON/OFF and forced stop of auto zero calibration
(see Item 6.5.2) is notpermitted during auto zero calibration. Auto Zero Calibration
Cancel cannot be performed with the key lock to ON. To cancel auto zero calibration
forcedly, set the key lock to OFF and then execute Auto Zero Calibration Cancel .
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.
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.
