GLP is a set of functions that allows storage and retrieval of data
regarding the maintenance and status of the electrode.
All data regarding pH, Rel mV, EC and NaCl calibration is stored for the
user to review when necessary.

EXPIRED CALIBRATION
For pH calibration, this instrument allows the user to set the number of
days before the next required pH calibration. This value can be set from
1 to 7 days. The default setting is OFF (disabled).
When calibration has expired the “CAL” and “INTV” tags will blink to
warn the user that the instrument should be recalibrated.
For example, if a 4 days time out has been selected, the instrument will
issue the alarm exactly 4 days after the last calibration.
If the expiration value is changed (e.g. to 5 days), then the alarm will
be immediately recalculated and appear 5 days after the last calibration.
Note: If the instrument was not calibrated, the “CAL” “INTV” tags will
be displayed even if the feature is disabled in SETUP menu.
