Vaisala RFL100 - Maintenance; Changing the Probe Filter

5. Maintenance
5.1 Cleaning RFL100
• Lint-free cloth
• Isopropyl alcohol (70%)
Do not spray anything directly on the RFL100, since that may deposit impurities
on the sensor.
1. Remove the data logger from the mounting bracket.
2. Moisten some lint-free cloth with isopropyl alcohol (70%).
3. Wipe the data logger and the mounting bracket.
4. Check the filter on the probe. If the filter becomes contaminated, it is very likely to aect
the humidity measurement since residue on the filter will retain some moisture. If the filter
is dirty, replace it with a new one. See Changing the Probe Filter (page 28).
5. Insert the data logger back in the mounting bracket.
5.2
Changing the Probe Filter
• New filter for the probe
Filter on the probe should be replaced when it is damaged or dirty. You can change the probe
filter without disconnecting the probe from the data logger.
The sensors are easily damaged when the filter is not in place.
Handle the probe carefully.
CAUTION!
1. Turn the filter counter-clockwise to loosen it.
2. Remove the filter from the probe. Be careful not to touch the sensors with the filter.
3. Install a new filter on the probe, and tighten it so it is finger-tight. Make sure the filter sits
straight and meets the thread properly.
