8.3.2 Preference Order of Output Hold Value
The output hold value takes the following preference order:
During error occurrence
During calibration
During maintenance
During warm-up
Preference order (high)
8.3.2E.siki
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.
8.3.3 Output Hold Setting
Table 8.5 lists parameter codes with set values for individual set items.
Table 8.5 Parameter Codes for Output Holding
Set items Parameter code Set value
During warm-up C04 0 4 mA
1 20 mA
2 Holds Set value
During maintenance C05 0 Without hold feature
1 Last measured value.
2 Holds set values.
During calibration C06 0 Without hold feature
1 Last measured value.
2 Holds set values.
During error occurrence C07 0 Without hold feature
1 Last measured value.
2 Holds set values.
Note: "C07" is not displayed when option code "/C2" or "/C3" (NAMUR NE 43 compliant) is specified.
8.3.4 Default Values
When the analyzer is delivered, or if data are initialized, output holding is by default as shown in Table
8.6.
Table 8.6 Output Hold Default Values
Status Output hold (min. and max. values) Preset value
During warm-up 4 mA 4 mA
Under maintenance Holds output at value just before maintenance started. 4 mA
Under calibration or blow-back Holds output at value just before starting calibration 4 mA
On Error occurrence Holds output at a preset value. 3.4 mA
