RH CALIBRATION INSTRUCTIONS
(Continued)
Increment RH Output
This will shift the RH output linearly up in 0.5% steps. Switch 4 must be set to ON first. After switch 4 is on, each time switch
5 is set ON the RH output will increase by 0.5%. The increase goes into effect each time switch 5 is set to ON.
Decrement RH Output
This will shift the RH output linearly down in 0.5% steps. Switch 4 must be set to ON first. After switch 4 is on, each time
switch 6 is set ON the RH output will decrease by 0.5%. The decrease goes into effect each time switch 6 is set to ON.
Reset RH Output
This will reset the RH output back to the original calibration. Switch 4 must be set to ON first. After switch 4 is on, toggle
switches 5 and 6 ON then OFF. After 5 and 6 are OFF, slide switch 4 OFF.
When all calibration is completed, remember to place the switches back into the positions that correspond to the output
needed as shown in
FIGURE 7
.

TEST SELECTION SWITCHES
TEST INSTRUCTIONS
Test mode will make the transmitter output a fixed 0%,
50%, or 100% value. The sensor will not affect the
transmitter output. This is used for troubleshooting or
testing only.
Switches 1, 2, and 3 are used for test mode. The output
will be a fixed 0%, 50%, or 100% signal that corresponds
to the output selected with switches 6, 7, and 8. Refer to
FIGURE 8
for switch settings.

RH CONVERSION FORMULAS
4-20 mA
([mA signal] -4) / 0.16 = percent RH
12 mA output signal
(12 - 4) / 0.16 = 50% RH
0-5 VDC
[VDC signal] / 0.05 = percent RH
1.25 vdc output signal
1.25 / 0.05 = 25% RH
0-10 VDC
[VDC signal] / 0.10 = percent RH
7.50 vdc output signal
7.50 / 0.10 = 75% RH
