8. Detailed Data Setting
For semi-automatic calibration, “under calibration” is the time required from entering
calibration instructions to perform a, either by using the touchpanel or by a contact
input, calibration 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 “Blowback” (see Section 10.2, “Blowback” later in this manual)
During semi-automatic blowback:
“During blowback” is the time required after pressing the blowback start key, by using
the touchpanel or entering a blowback start instruction by using a contact input, until the
blowback time and output stabilization time elapse.
During automatic blowback:
“During blowback” is the time required after reaching the blowback start time until the
blowback time and output stabilization time elapse.
(5) On Error occurrence
This is the time at 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 blowback
Under maintenance
During warm-up
Preference order (high)
Ex8.2.2.eps
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.
