3.9 Checking the Settings
"0/4 mA" and „20 mA“ enable to netune the
analog output to compensate possible devia-
tions based on electronics tolerances:
• Set "Signal" to 0 mA or 20 mA
• measure the output current,
• adjust it to the expected value.
Accepted range: -10,000 ... +10,000
"Hold" selects the output´s behaviour during
calibrations.
If set to Yes,
• the analog output is xed to the last measu-
red value
;
• concentration alarms, which may otherwise
be triggered by the concentrations of the
calibration gases, are supressed.
If set to No,
• the analog output signal always corre-
sponds to the actual measured value during
calibration; this may trigger alarms if limits
are exceeded.
Note!
This behaviour may be undesireable if e.g.
the unit is connected to a data acquisition
system.
