the GLP or ‘Good Laboratory Practice’ file saves detailed information
about calibrations. It also includes diagnostic information about the sensors.
Calibrations are logged into a file, the GLP, for later review as needed. A single
GLP file is utilized to store all calibration records and is capable of storing 500
records. once the GLP file is full, the instrument will begin to overwrite the
oldest record with each new calibration record.
In order to keep all of your GLP records, periodically download
the GLP to Data Manager and export it to another program.
Otherwise, the unit will overwrite the oldest record once
the memory is full. Also, since Data Manager saves GLP
files under the Unit ID, you must periodically export and
rename the GLP file on your PC or it will be overwritten
each time you upload the GLP file from the instrument.
Several calibration parameters are saved for each calibration record including
optional ones that can be enabled by the user. Standard parameters include
date/time stamp, calibration method, and sensor information. optional, user
selectable parameters include User ID, Probe ID, and User Fields 1 and 2.
the sensor specific information that is saved with each calibration point is
different for each sensor. the sensor specific values saved are:
Conductivity
Method (Spec Cond, Cond, Salinity)
Cal Value (value of calibration solution)
Sensor Value (Cell Constant)
temperature Reference (User selected in Sensor Setup menu)
temperature Compensation Coefficient %/°C (User selected in Sensor Setup
menu)
