Chart Notes
1.) First be sure that the +24 VAC power is being supplied to the
sensor. Second set the meter to DC volts and connect the meter
between ground and the 0-5 VDC input on the controller board or
between the 0-5 VDC output terminal on the sensor and its ground
terminal. Use an accurate humidity measurement device (such as an
aspirating psychrometer) to determine the RH percentage (relative
humidity) .
Use the “Output VDC” column on the chart to read the voltage
corresponding with the RH percentage column just measured. If the
measured voltage is within 3% of what is listed for the corresponding
RH, the sensor is functioning correctly. If it is not you will need to
replace the sensor.
