5 Maintenance
5.1 Cleaning the test port
Over time, dust can gather on the photodiode,
particularly if you leave the cover open for a while
or remove the adapter.
To retain high measurement accuracy, we
recommend that you clean the photodiode from
time to time.
Notice: Do not touch the photodiode in order to
avoid soiling or scratching the glass
cover.
1. Pop open the cover on the front of the OLP.
2. Unscrew the adapter by hand.
You can now access the photodiode.
3. Use a cotton swab dipped in isopropanol to
wipe off the photodiode. This is an effective
cleaning method that leaves no traces.
4. Blow off the test adapter with pressurized air
(e.g. anti-dust spray available in cans).
5. Screw the adapter back on.
6. Pop the cover back on.
Tip: To avoid premature soiling of the
assembly, keep the adapter in place and
the cover closed when you are not making
measurements.
