A. Make sure the battery voltage is between 9.6 and 16 VDC.
B. Verify sensors are plugged into the correct sensor connector and the
locking ring is securely in place (see Figure 2.4-18). Check connectors for
any corrosion on pins.
C. If Short Cut or VisualWeather is used to create the station program double
check the wiring diagram to see if it matches the physical wiring on the
sensor connectors on the back of the enclosure.
If CRBasic is used to create the station program verify channel
assignments and multipliers.
4.2.4 Unreasonable Results Displayed in a Variable
A. Inspect the sensor for damage and/or contamination.
B. Make sure the sensor is plugged into the correct sensor connector on the
back of the enclosure.
C. If Short Cut or VisualWeather is used to create the station program double
check the wiring diagram to see if it matches the physical wiring on the
sensor connectors on the back of the enclosure.
If CRBasic is used to create the station program verify channel
assignments and multipliers. Datalogger program may need to be changed.
