13 Maintenance and service
The operator is responsible for determining the maintenance intervals for the measuring
device.
PRIMES recommends a maintenance interval of 12months for inspection and validation
or calibration.
If the device is used only sporadically, the maintenance interval can also be extended up
to 24months.
13.1 Exchanging the protective window
The protective window in the beam entrance is a wearing part and can be replaced
if necessary. Low levels of contamination of the protective window can be carefully
removed when cooled with Isopropanol (observe the manufacturer‘s safety instructions).
In case of heavy, non-removable contamination or damage, the protective window must
be replaced with a new one.
The protective window is coated with an antireflection coating and has low
reflection values of less than 1%. To avoid increased reflection values, use only
original PRIMES protective windows.
Protective window diameter 55mm
Glass thickness 1,5mm
