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).
