APPENDIX

RH Test and Configuration DIP Switch Settings (Table 3)

IMPORTANT

• Only adjust these switches for troubleshooting or

recalibrating the sensor. (Adjustment is not
normally necessary.)

• For normal operation, always keep DIP switch 3

in the ON position. When DIP switch 3 is off, the
RH transmitter cannot read the sensor. This
inability-to-read forces the output to never
change.

Table 3. Test/Calibration Settings (Six-Switch Block).

0% RH Output (for Testing Only)

Transmitter always outputs a signal of 4 mA or 0 Vdc. The
sensor does not affect the transmitter output.

50% RH Output (for Testing Only)

Transmitter always outputs a signal of 12 mA, 2.5 VDC, or
5 VDC. The sensor does not affect transmitter output.

100% RH Output

Transmitter always outputs a signal of 20 mA, 5 VDC, or
10 VDC. The sensor does not affect the transmitter
output. Sensor doesn’t affect the transmitter output.

Normal Operating Condition

DIP switch 3 must be set in the On position for normal
operation. All other DIP switches must be set Off.
