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.)
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.

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.
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.
5 VDC. The sensor does not affect transmitter output.
100% RH Output
Transmitter always outputs a signal of 20 mA, 5 VDC, or
