12. GLP

Good Laboratory Practice (GLP)  allows the user to store and recall 

calibration data. Correlating readings with specific calibrations 

ensures uniformity and consistency. 
GLP information is included with every data log. pH calibration 

data is stored automatically after a successful calibration.
To view the pH calibration data:

 

y

Press GLP/ACCEPT when in Measurement mode. 

 

y

Use the 



 keys to scroll through the calibration data 

displayed on the third LCD line: Offset, slope, pH calibration 

solutions, Time, date, calibration expiration time.

 

y

Press ESC or GLP/ACCEPT to return Measurement mode.

If calibration expiration time is disabled, “EXP WARN DIS” is 

displayed.

If the instrument has not been calibrated or calibration has been 

deleted, the blinking “NO CAL” message is displayed in GLP.
