other cases.
Remote start
Whether the auto calibration is set at ON or OFF, an auto calibration is available by keeping the
remote start input closed for at least 1.5 seconds.
When an auto calibration starts, the measurement screen appears automatically.
During auto calibration, any key operation is not permitted other than operations such
as key lock ON/OFF and “Forced stop of auto calibration” (see Section 6.4.2.2).
When the key lock is set at ON, even the “Forced stop of auto calibration” cannot be
performed. To cancel auto zero calibration forcedly, set the key lock to OFF and then
execute “Forced stop of auto 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 calibration, and then repeat it in the set cycle.
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.
