Preference Order Of Output Hold Value; Output Hold Setting; Default Values - YOKOGAWA ZR402G User Manual

In a semi-automatic calibration, "during calibration" is the time, starting when a calibration
instruction is executed with an infrared switch or a contact input, to make a series of
calibrations, until the preset output stabilization time elapses.
In an automatic calibration, "during calibration" is the time, starting when automatic
calibration is carried out at the calibration start time, until the preset output stabilization time
elapses.
(4) "Error" appears when Error 1 to Error 4 are being issued
8.2.2

Preference Order of Output Hold Value

The output hold value takes the following preference order:
Preference order (high)
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.
