Description
Monitoring without pump (diffusion)
Monitoring with pump (with pump adapter)
The capture range refers to a measured value range
within which minor variations in measured values (such
as signal noise, variations in concentration) do not cause
variations in the display. Measured values outside the
capture range will be displayed with the actual measured
value.
Measurement with pump and any accessories (e.g.
hose, probe) for clearance measurements of specific
areas (X-am 8000 only).
Leak search measurement (X-am 8000 only)
Benzene/pre-tube measurement (X-am 8000 only)
Peak value
Test for alarm triggering.
Test for accuracy and alarm triggering.
If a special state is signalled, the user is not warned of
gas concentrations which may be dangerous.
The following device features are special states:
First set-up / configuration with the PC menu, prepara-
tion phase of the wizards, maintenance wizard bump test
and calibration, warm-up 1 of the sensors.
The D-Light feature allows the user to check and indicate
compliance with certain settings.
The CatEx, IR, and PID sensor types are designated as
physical sensors. There are also the electrochemical
sensors.
