Item 6.4.2) is not permitted during auto calibration. “Stop Auto Calibration” cannot
be performed with the key lock to ON. To cancel auto calibration forcedly, set
the key lock to OFF and then execute “Stop 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.
