AERONET Instrument Troubleshooting Interface - Solutions for CONSTANT HUMIDITY STATUS Flag

Condition(s)
Flag if at least 4 days during a week only humidity statuses are reported from early morning till m=2.5.
Flag if humidity statuses are reported from early morning till m=2.5.

How To Check/Test
Model 5: On the control box go to VIEW > BAT > red button (HH 0 = dry, HH 1 = wet)
(See Model 5 check wet sensor)

Model T: On the control box go to MEASURES > Wetting
(See Model T wet sensor check)

Solution Level 1 (< 5 minutes)
1. Ensure wet sensor is secured and facing upwards.
2. Ensure gold sensing contacts are clean.
3. Check the connector and HH port for wetness or corrosion (oxidation)

Solution Level 2 (more involved)
1. Disconnect the wet sensor, then check the HH status. If the status is still 'wet', then the problem is with the connector panel or control box.
2. Disconnect the connector panel, then check the HH status. If the status is still 'wet', then the problem is with the control box.

Solution Level 3 (last resort)
1. If the problem is with the control box, check/reseat internal connections and test again (Model 4 and 5 ONLY)
2. Replace the wet sensor and/or other faulty components.
