The probe is measured by two single-ended analog input channels, one for temperature and one for relative humidity. CAUTION Always connect the blue lead to the datalogger first, followed by the black, white, and clear leads. Connect the brown (power) lead last. 7.4 Programming This section is for users who write their own datalogger programs. A datalogger program to measure this sensor can be created using Campbell Scientific's Short Cut Program Builder Software. You do not need to read this section to use Short Cut. 11
