8301-067 Humidity Sensor Test Value Outputs
This sensor has the ability to output fixed test signals
when testing/troubleshooting sensor operation.
These settings are to be used for sensor testing/
troubleshooting only and need to be removed before
unit can resume normal operation. These settings allow
the sensor board to output 0% RH, 50% RH and 100%
RH. When these settings are active, the actual humidity
sensor is ignored. DIP switches 1, 2 and 3 are used to
override the output to a test signal. See Figure 63 for
DIP switch/output configuration.
NOTE:
If any DIP switches are disrupted, they will need
to be returned to the off state in order for the
humidity sensor to return to normal operation.

8301-067 Humidity Sensor Calibration
The 8301-067 sensor has the ability to be calibrated
via the sensor control board through the use of the
DIP switches and/or the use of ZERO P1 or SPAN P2.
It is not advised to calibrate this sensor through these
means. Any calibration for the unit operation can be
done by applying an offset to the sensor input channel
using the TEC-EYE service tool.
