8. Detailed Data Setting
For semi-automatic calibration, “under calibration” is the time required from entering
calibration instructions, to perform a calibration either by using the touchpanel or by a
contact input, until the output stabilization time elapses.
For automatic calibration, “under calibration” is the time required after performing an
appropriate calibration, until the output stabilization time elapses.
(4) During “Blow-back” (see Section 10.2, “Blow-back,” later in this manual)
Under semi-automatic blow-back:
During blow-back” is the time required after pressing the blow-back start key, by
using the touchpanel or entering a blow-back start instruction by using a contact
input, until the blow-back time and output stabilization time elapse.
Under automatic blow-back:
During blow-back” is the time required after reaching the blow-back start time until
the blow-back time and output stabilization time elapse.
(5) On Error occurrence
This is the time of which any of Errors 1 to 4 occurs.
8.2.2 Preference Order of Output Hold Value
The output hold value takes the following preference order:
On error occurrence
Under calibration or during blow-back
During warm-up
Under maintenance
Preference order (high)
8.2.2.siki
For example, if the output current is set to 4 mA during maintenance, and no output-
hold output for during calibration is preset, the output is held at 4 mA during the
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.
