7.2 pH
• From the “GLP data” menu, select the “pH” option and press <OK>.
• All data regarding last pH calibration appear:
offset, acidic slope, basic slope, used buffers,
time and date of the procedure.
• Use the arrow keys to scroll the stored data of
last 5 calibrations.
• Press ESC to return to the “GLP data” menu.
NoteNote
NoteNote
Note The “C” label near the buffer value indicates a custom point, while the
“H” indicates HANNA standard value.
If a quick calibration was performed, the buffer values are replaced
with the “Quick calibration” indication.
If calibration was cleared, the offset and slope values are the default
ones, and the message ”Old calibrations cleared” appears.
If no pH calibration has been performed, a warning message advise
the user. Press <OK> to return to the previous screen.
7.3 DISSOLVED OXYGEN
• From “GLP data” menu select the “Dissolved
oxygen” option and press <OK>.
• All data regarding last DO calibration appear:
calibrated points, % saturation or concentra-
tion, time and date.
• Use the arrow keys to scroll the last 5 memo-
rized calibrations.
• GLP calibration data for DO include 3 options: 2-point % DO calibration,
single point % DO calibration and concentration DO calibration.

Notes The “C” label near the calibration point indicates a custom point, while
the “H” means HANNA standard value.
When the % DO range is calibrated, also the DO concentration range
is calibrated, and vice versa.
If no DO calibration has been performed, a warning message advises
the user. Press <OK> to return to the previous screen.
