8.3.2
Preference Order of Output Hold Value
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 during maintenance, and no output-
hold output during calibration is preset, the output is held at 4 mA in the maintenance
display. However, the output hold is released at the time of starting the calibration, and
the output will be held again at 4 mA after completing the calibration and when the
output stabilization time elapses.
