8.2.1 Definition of Equipment Status
(1) During warm-up
"During warm-up" is the time required after applying power until sensor temperature stabilizes at
750ºC and the instrument is in the measurement mode.
(2) Under Maintenance
"Under maintenance" is the time that starts when you move to the Execution/Setup display by
touching the [Setup] key on the Basic panel display and ends when you return to the Basic panel
display. It includes when you operates keys on lower level menu displays of the Execution/Setup
display.
(3) Under Calibration (see Chapter 9, Calibration, later in this manual)
For manual Calibration, "Under calibration" is the time that starts when you move to the Manual
calibration display (Figure 7.30) from the Calibration display, lasts while you are operating keys
for performing calibration manually, and ends when you press the End key and after a preset hold
time has elapsed.
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
hold (output stabilization) time elapses.
For automatic calibration, "Under calibration" is the time required, after performing an appropriate
calibration until the hold (output stabilization) time elapses.
(4) During Blow back (see Section 10.4, Blow Back, later in this manual)
During semi-automatic blow back:
"During semi-automatic 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 hold (output stabilization) time elapse.
During automatic blow back:
"During automatic blow back" is the time required after reaching the blow back start time until the
blow back time and hold (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:
Preference order (high)
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 hold (output stabilization) time
elapses.
On error occurrence
Under calibration or during blow back
Under maintenance
