Question

RH data is overflowing and rolling over. What can be done to fix this?

Answer

In cases of severe contamination such as the presence of conductive dust or liquid, readings can become significantly higher and will wrap around. To protect against this, it is recommended to use the factory-installed ePTFE cover. Generally, after contamination a bake and hydrate process will recover accuracy however in severe contamination cases, accuracy may be irrecoverable.
