GLP (Good Laboratory Practice) is a set of functions that allows the user to store or recall data
regarding the probe calibration. This feature also allows the user to associate readings with specific
calibrations.
To view GLP data select “GLP” from the “Status” menu. The
complete list of available parameters appears. Select the desired
parameter to view the stored GLP information.
Note: If no calibration data is available for the selected
parameter, the display shows the message “No GLP data
available for this measurement”. Press <OK> to return
to the previous screen. GLP data is stored for the last 5
calibrations. This calibration history allows the user to
detect when readings start to change and sensors may
require cleaning or replacement.
pH
• From the “GLP” menu, select the “pH” option.
• Data regarding the last pH calibration will be displayed:
offset, acidic slope, basic slope, buffers used, time and
date of the calibration.
• Use the / keys to scroll through the stored data for the
last 5 calibrations.
• Press ESC to return to the “GLP” menu.
Note: A “C” label near the buffer value indicates a
custom point, while an “H” indicates a Hanna Instruments
standard buffer value.
If a quick calibration was performed, the buffer values are
replaced with the “Quick calibration” indication.
If no pH calibration has been performed or if calibration
was cleared using the the “Restore factory calib.” option the offset and slope values are set
to default, and the message
“Factory calibration” is displayed. Press <ESC> to return to the previous screen.
Note: The probe status screen will automatically be displayed when the probe sensor status
has changed. If this occurs, the “Measurement Screen” and “Parameter Selection” softkeys
are available (see Meter Initialization).
