5.7 Checking the Settings
" 0/4 mA
" enables to finetune the analog
output: Set " Signal " to 0 mA and, while
measuring the output current, adjust it to the
expected value.
Accepted range:
-10,000
…
+10,000
" 20 mA
" enables to finetune the analog
output: Set " Signal " to 20 mA and while
measuring 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 fixed 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.
