Campbell Scientific ST350 Strain Transducer for Structural Testing - Manual (Page 29)

Section 8. Datalogger 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 if using LoggerNet or by
using PC9000 software for the CR5000 or CR9000X. Short Cut or PC9000 are
used to create the datalogger program, the sensors should be wired to the
channels shown in the wiring diagram created by either program. Any
reference to specific channel assignments is for these examples only.
