CS451/CS456 Submersible Pressure Transducer
7.4.1 CRBasic Programming
Dataloggers that use CRBasic include our CR200(X)-series, CR800, CR850,
CR1000, CR3000, and CR5000. These dataloggers use the
SDI12Recorder()
to read the CS451/CS456. A multiplier of 1.0 and an offset of 0.0 yield water
level in psig and temperature in degrees C.
The SDI12Recorder() instruction has the following form:
SDI12Recorder( Destination, Output String, Multiplier, Offset )
7.4.1.1 Example Program for CR200(X)-Series Datalogger
'CR200(X) Series
'Declare the variable for the water level measurement

'Rename the variable names
Alias CS451(1)=Level
Alias CS451(2)=Temp_C
