Suitable environment
Device inspection and adjustment must be performed in an envi-
ronment with clean air. This means that the ambient air must be
free of hydrocarbons and toxic gases.
During device inspection and adjustment the device will indicate
whether the ambient air is clean (for instance:
Use clean air!
).

Device inspection
Device inspections have the task of ensuring the functionality of
the device and, in particular, the display for the measuring mode.
The probes and probe hoses used with the device must also be
visually inspected for each device inspection (/3/).
Note:
In addition to the device inspection, the response time must be
measured and documented regularly.
