12. GLP
Good Laboratory Practice (GLP) refers to a quality control function used to ensure uniformity
of sensor calibrations and measurements. Press GLP/ACCEPT to open latest calibration
file. Use the keys to scroll stored information (offset and slope values, used buffers
together with the temperature, time and date of the last calibration, calibration warnings).
This information is also included with every data log.
If the instrument has not been calibrated, blinking CAL tag and "NO CAL" message are displayed.
The GLP slope percentage is referenced to the ideal slope value at 25 °C.
Additionally, for MW151, the electrode condition indicator displays its status after the last
calibration.
Use the keys to display the last calibration date (yyyy.mm.dd) together with the
current reading.
Note: When using custom buffers, "CUST1" and "CUST2" tags are displayed. If only one
custom buffer is used, "CUST1" is displayed together with its value. (MW151 only)
