Therm109 // CR5000 logger


GeogAero Jul 12, 2017 02:41 PM

Hi there, 

I'm completely new to using the Campbell logger model CR5000, and I'm having trouble using the therm109 function.

It no longer is recognised as a variable (ie it doesnt turn blue) in the program, and therefor the code will not compile. 

The instructions in the manual are unfortunately not helpful :

7.4.1.1 Therm109() Instruction

CRBasic dataloggers measure the sensor body temperature (°C) using the Therm109() instruction.

Therm109(Dest, Reps, SEChan, Mult, Offset)
Use the default values for Mult and Offset, which output the temperature in °C.

Any advice on how to fix this would be much appreciated, we used to use the CR10X without a problem and this did not occur.

You need to update the CR5000 to OS Std 7, and update the software (LoggerNet, CRBasic Editor) to use the right files associated with OS Std 7. Then the Therm109 instruction will work with the CR5000. OS Std 6 would also work, but Std 7 is recommended. The download is here:

Running the executable file (.exe) will install the appropriate files and make the *.obj file available for updating the OS in the Logger with DevConfig.
