GOOD LABORATORY PRACTICE (GLP)
GLP is a set of functions that allows data storage (and
retrieval) about the electrode status and maintenance.
All data regarding pH and relative mV calibrations are
stored in the instrument memory.
To enter GLP mode, press SHIFT and then GLP key.
If no calibration has been performed, the “no CAL”
message will blink.
CALIBRATION TIME-OUT ALARM
The instrument allows to set the number of days (from
1 to 7) before the next required pH calibration. The
default 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.

SETUP
Setup mode allows viewing and modifying the following
parameters:
•
Calibration alarm time-out
•
One-point calibration behavior
•
Temperature measure unit
•
Current date (yyyy.mm.dd)
•
Current time (hh:mm)
•
Printer status
(
AD132
only)
•
Auto-off
•
Baud rate
(serial communication,
AD132
only)
•
Command prefix
(serial communication,
AD132
only)
•
Instrument ID
• To enter SETUP mode, from measurement mode press
SHIFT and then SETUP.
• Press CAL to change the
item value. The selected
item (e.g. hour, while
setting the time) and
“CFM” tag will blink.
• Use the arrow keys to
scroll the available values.
