7.3 Wiring

Connections to Campbell Scientific dataloggers are given in Table 7-1. The

probe is measured by two single-ended analog input channels, one for

temperature and one for relative humidity.

Always connect the blue lead to the datalogger first,

followed by the black, white, and clear leads. Connect the

brown (power) lead last.

CAUTION

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.
