GOOD LABORATORY PRACTICE (GLP)

GLP is a set of functions that allows storage and retrieval of data regarding the

maintenance and status of the electrode.

All data regarding the last calibration (one, two, three, four or five-point) is

stored for the user to review when necessary. This data includes the following:

calibration time stamp, offset (mV), average of slope (%), calibration buffers

and the time until a new calibration is required.

CALIBRATION ALARM TIME-OUT

These instruments allow the user to set the number of days before the next

required calibration. This value can be set from 1 to 7 days. The default

setting is OFF (disabled).

The instruments check if the time-out time has expired. If the time elapsed, the

CAL INTV tags will blink as a reminder.

Note: If the instruments were not calibrated, the CAL INTV tags will be

displayed even if the feature is disabled in SETUP menu.

LAST CALIBRATION DATA

Last calibration data are stored automatically after a successful calibration.

To view the pH calibration data, press GLP while in measurement mode.

The instruments will display the time (hh:mm) of the last calibration.

Press the ARROW keys to view the next logged calibration parameter

(pressing the ºC key):

 The date (yyyy.mm.dd).

 The pH calibration offset.

 The pH calibration slope (the GLP slope is the average of the calibration

slopes; the percentage is referred to the ideal value of 59.16 mV/pH).
