8.2.2 Preference Order of Output Hold Values
The output hold value takes the following preference order:
During error occurrence
During calibration
During maintenance
During warm-up
Preference order (high)
8.2.2E.siki
For example, if the output current is set to 4 mA for “under maintenance”, and no
output-hold output for during calibration is preset, the output is held at 4 mA during the
“ under 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.
8.2.3 Output Hold Setting
Table 8.4 lists parameter codes with set values for individual set items.
Table 8.4 Parameter Codes for Output Holding

8.2.4 Default Values
When the analyzer is delivered or data are initialized, the output current settings are by
default as shown in Table 8.5.
Table 8.5 Output Current Default Values
Status Output hold (min. and max. values)
During warm-up 4 mA
Under maintenance Holds output at value just before maintenance started.
Under calibration or blow-back Holds output at value just before starting calibration
or "blow-back."
On Error occurrence Holds output at a preset value.
