Detailed sensor calibration information is stored in the Good Laboratory Practice (GLP) file for later review.
One GLP file is used to store all calibration records. The instrument’s internal memory can save up to 400 individual
calibration records. After 400 records, the instrument will overwrite previously stored calibration records, starting with
the oldest.
To prevent the permanent loss of GLP records, periodically download the GLP file to a computer using the KorDSS
software.
NOTE: GLP files uploaded to the PC will overwrite a previously downloaded GLP file if it has the same file name.
To prevent data loss, move or rename previously downloaded GLP files before downloading the GLP file.
