After calibration processing of calibration files
AC-9
As of October 2012, AC-9 calibrations have been reprocessed with new 'Sit' values from Wetlabs AC meter protocol document, rev.Q. The processing directory for AC9 calibrations is /pb/AC9/cals/ instrument number(184) /QWATER/ year/date folder.
Each time the instrument is sent back for a factory calibration, the new disc should be checked for updated temp and sal correction coefficients and calibration history should be updated in the ac9cal.txt inside of the /cals/0184/DeviceFiles/ directory. Note that if coefficients have changed, goac9.par will need to be updated in the fallowing cruise processing.
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. Hit the last button ts_cal to view the whole time series.
