5. Programming
This section is for users who write their own datalogger
programs. A datalogger program to measure this sensor can be
generated using Campbell Scientific’s Short Cut Program
Builder software. You do not need to read this section to use
Short Cut. NOTE
The datalogger is programmed using either CRBasic or Edlog. Dataloggers
that use CRBasic include our CR200(X) series, CR800, CR850, CR1000,
CR3000, CR5000, and CR9000(X); see Section 5.1. Dataloggers that use
Edlog include our CR10, CR10X, CR23X, and CR7; refer to Section 5.2.
CRBasic and Edlog are included in our LoggerNet, PC400, and RTDAQ
software.
The Steinhart-Hart equation is used to calculate the temperature. The
coefficients used for the Steinhart-Hart equation are as follows:
A=1.129241*10^-3
B=2.341077*10^-4
C=8.775468*10^-8
If applicable, please read “Section 5.3—Electrical Noisy Environments” and
“Section 5.4—Long Lead Lengths” prior to programming your datalogger.
Measurement details are provided in Section 6.
