Applying Calibrations


JorgeO Mar 5, 2012 08:29 AM

Hi.The company i work for has several towers for meteorological measurement in Southamerica , some of them use a Campbell logger. We can't control the calibration values introduced to each logger by the people who build up the towers and collect the data, so we are bounded to, somehow, filter the data that we receive from them each month to make sure it is trustworthy.In order to do so we would like to apply our own calibrations values(offset and slope) to the data we get( they normally send us the output data in .dat files).I would like to know if it is possible to do so, perhaps with a CRBASICS program?.Thank you very much.Jorge.

P.D.I know i could make a program with our calibrations values, but the problem is that i couldn't send that program to the logger.

The simplest method is to use the calibrations for each sensor within the program.

If a sensor is changed out, the program is modified to use the new sensor calibrations.

I do not think it is possible to feed a *.dat file back into a logger and have it post-process the data.

Post-processing is usually handled in a database or spreadsheet and should be routine enough to be done easily.

Cheers
