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.)
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 4 for
switch settings.
