Preference Order of Output Hold Values
The output hold value takes the following preference order:
During error occurrence
During calibration
During maintenance
During warm-up
Preference order (high)
8.2.2E.siki
For example, if the output current is set to 4 mA for “under maintenance”, and no
output-hold output for during calibration is preset, the output is held at 4 mA during the
“ under maintenance” display. However, the output hold is released at the time of
starting the calibration, and the output will be again held at 4 mA after completing the
calibration and when the output stabilization time elapses.
