RH Test and Calibration Dip Switch Settings (See Figure #3 and Figure #6)
Note: Do not adjust these switches unless you are using them to troubleshoot or recalibrate the sensor. Dipswitch
#3 should always be left in the ON position during normal operating conditions. Failure to do so will not allow the
RH transmitter to read the sensor (The output will always remain the same).
0% RH Output - Transmitter always outputs a signal of 4 mA or 0 VDC. Sensor doesn’t affect the transmitter
output. (For Trouble Shooting Purposes Only)
50% RH Output - Transmitter always outputs a signal of 12 mA, 2.5 VDC, or 5 VDC. Sensor doesn’t affect the
transmitter output. (For Trouble Shooting Purposes Only)
100% RH Output - Transmitter always outputs a signal of 20 mA, 5 VDC, or 10 VDC. Sensor doesn’t affect the
transmitter output. (For Trouble Shooting Purposes Only)
Normal Operating Condition - The DIP switch must be set in this position for the RH signal to change, due to the
actual measurement of the Relative Humidity by the humidity sensor.
Increment RH Output - This DIP switch will allow you to calibrate the sensor through the software. The switch
must be toggled from the Off to the On position and then returned to the Off position for an
increase of 0.5% RH. This means that if your humidity has drifted 1% over a certain time
period, you will be able to toggle the Increment RH Output switch (2) times in order to
slide the whole curve upward 1%. Note: This is only a single point calibration, and is not
recommended for critical applications. Please contact the factory before doing any
field calibration.
