7.4.1 Preparing Calibrations
When done, press
left several times to return
to SETUP:
If you use analog output signals, you may
want to check or setup, how the analog si-
gnals proceeds during calibrations.
To do so, enter IN-/OUTPUTS - ANALOG
OUTPUTS and enter the submenu of your
analog output:
The menu to the left shows up, where the last
line parameter species the behaviour during
calibrations:
When
"Hold" is 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.
When set to No,
• the analog output signal always corre-
sponds to the actual measured value during
calibration; this may trigger alarms when
limits are exceeded.
Note!
This behaviour may be undesireable if e.g.
the unit is connected to a data acquisition
system.
Setup this parameter in a way to serve your
needs.
If you do not intend to carry out valve sup-
ported calibrations, continue with 7-17.
