0-5 VDC Output Wiring (24VAC Power)
*Chart Notes:
1. First, be sure that +24VAC power is being supplied to the sensor. Second check the
sensor output. Set the meter to DC volts and connect the meter between ground
and the 0-5 VDC input terminal on the controller board or between the 0-5 VDC
output on the sensor and its ground wire or you can measure voltage at the 0-5 VDC
and GND terminals on the sensor located at the sensor installtion location.
After measuring the voltage use an accurate humidity measurement device to
determine RH (relative humidity) such as an aspirating psychrometer. Use the
Output VDC column to read the Output Voltage corresponding with the RH
percentage measured with the psychrometer. If the measured voltage is within 3%
of what is listed for the corresponding RH, then the sensor is functioning properly.
