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)
8.3.2E.siki
For example, if the output current is set to “4 mA” during maintenance, and “without 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.
8.3.3 Output Hold Setting
Table 8.5 lists parameter codes with set values for individual set items.
