How to adjust your hygrometer
If your hygrometer does not read the correct relative humidity it can be adjusted or reset in
the following way:
• Lay a moist cloth on the back of the hygrometer for approximately 30 minutes.
After that time the hygrometer should read 95% RH.
If it does not read 95% RH it should be adjusted
as follows:
1. Pass the end of a flat head screwdriver
through hole (1) and insert it into slot (2).
2. Turn the spiral spring (3) until the indicator
needle reads 95% RH.
3. The hygrometer should now show more
accurate readings.
