Good Laboratory Practice - ADWA AD1000 User Manual

ONE-POINT CALIBRATION
• To perform a single point calibration,
press CAL after the first calibration
point has been confirmed.
The instrument will store the one-point calibration data
and return to normal measurement mode.
GLP (GOOD LABORATORY PRACTICE)
GLP is a set of functions that allows data storage (and
retrieval) about the electrode status and maintenance.
All data regarding pH, relative mV and ISE calibrations
are stored in the instrument memory.
CALIBRATION TIME-OUT ALARM
The instrument allows to set the number of days (from
1 to 7) before the next required pH calibration. The de-
fault setting is "OFF" (disabled).
At start-up the instrument checks if the calibration time-
out has expired. If yes, the "CAL DUE" message blinks
to advise the user that a new calibration is required.
Note: If the instrument was not calibrated or all cali-
bration data were cleared, the "CAL DUE"
message is displayed even if the feature is dis-
abled in the setup menu.
