HX93A, HX93DA SERIES	16
RH/Temperature Transmitter

16. Maintenance

If your Humidity transmitter will be used in a dusty environment, the protective sensor filter, if clogged, may be removed for cleaning. Unscrew the protective cover and gently blow compressed air through the filter screen. A soft brush may also be used to remove dirt particles from the screen.

If the sensor is subjected to 100% condensation, it must be dried to obtain correct readings. There will be no permanent damage or calibration shift to the unit.

Units should not be exposed to high concentrations of ammonia or alcohol vapors.
