7.1 Wiring
The wiring diagram for the BlackGlobe to a Campbell Scientific datalogger is
given in TABLE 7-1. Temperature is measured with one single-ended input
channel and a voltage excitation channel. Multiple probes can be connected to
the same excitation channel (the number of probes per excitation channel is
physically limited by the number lead wires that can be inserted into a single
voltage excitation terminal, approximately six).
