| Do not spray anything directly on the RFL100, since that may deposit impurities on the sensor. |
- Remove the data logger from the mounting bracket.
- Moisten some lint-free cloth with isopropyl alcohol (70 %).
- Wipe the data logger and the mounting bracket.
- Check the filter on the probe. If the filter becomes contaminated, it is very likely to affect 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.
- Insert the data logger back in the mounting bracket.
