Calibration process procedures

After calibration processing of calibration files

AC-9

As of October 2010, AC-9 calibrations have been reprocessed with new 'Si_t' values from Wetlabs AC meter protocol document, rev.P. The processing directory for AC9 calibrations is /pb/REPROCESS_2010/AC9/cals_reprocess/ instrument number(184) /QWATER/ year/date folder.

To process the calibration files, the device number _watertemp.txt file must be updated with the latest temperature value and .dat files must be present in the folder you wish to process in. ac9cal.m sources ac9cal_def.par in the cals_reprocess/LIST folder.

Reviewing calibrations

After processing, it is good to compare the latest calibration processed values with previous ones. For this, data from the _ave.txt files(which should be linked by you from the .txt files in the year/date folder) is added to the qcal_a_yy_yy.txt and qcal_c_yy_yy.txt files. ac9cal.m is restarted and the qcal file is now the *yy_yy.txt folder.
