15 Maintenance and service
15.1 Maintenance intervals
The operator is responsible for determining the maintenance intervals for the measuring device.
PRIMES recommends a maintenance interval of 12 months for inspection and validation.
If the device is used only sporadically, the maintenance interval can also be extended up to 24 months.
Please note that the safety and warning functions of the device must be checked regularly.
15.2 Cleaning
15.2.1 Cleaning the device surfaces
1. After a measurement, let the device cool down for an adequate period of time.
2. Close all device openings.
3. First clean the device surfaces with cleaned, oil-free compressed air.
4. For further cleaning, use a mixture of distilled water and isopropanol in a ratio of approx. 5:1.
Use lint-free cleaning cloths that do not cause scratches. This can be e.g. microfiber cloths or paper
towels from the cosmetics sector.
5. If these steps are not sufficient, please contact PRIMES or your PRIMES distributor.
15.2.2 Cleaning the protective window
1. After a measurement, let the device cool down for an adequate period of time.
2. Dismount the protective window according to chapter 15.3.2 on page84.
3. First clean the protective window with cleaned, oil-free compressed air.
4. For further cleaning, use isopropanol (observe the manufacturer‘s safety instructions).
The coating of the protective window is particularly sensitive to scratches. Use cloths suitable for clean-
ing protective glasses.
5. Replace the protective window with a new one if the contamination cannot be removed or if it is dam-
aged.
15.3 Exchanging the protective window
The protective window in the beam entrance is a wearing part and can be replaced if necessary.
The protective window is coated with an anti-reflective coating and has low reflectance values of
less than 1%. To avoid increased reflection, use only original PRIMES protective windows.
