solution is recognised.
(If an error occurs, replace the buffer solution)
9. Press the key. The value of the buffer solution
that
has been recognised is shown on the display.
10. Press the key. The indication OFFS PH will
appear on the display. Wait for 30 seconds for
calibration of the probe.
The instrument will calculate the
OFFSET value
and
show the quality of the electrode as a percentage
value.
11. After 5 seconds the indication CAL PH will appear
on the display and the 4 pH LED will flash.
12. Wash the electrode in bottle n° 2
containing clean water.
13. Dip the electrode into bottle n° 3 containing the
solution with a pH of 4 leaving it there for 15
seconds .
14. Press the key

17. Press the key. The indication GAIN PH will
appear
on the display. Wait for
30 seconds.
The instrument will calculate the GAIN value and
show the quality of the electrode as a percentage value.
18.
The instrument will save the parameters calculated
and the indication

display
for one second. The instrument will then exit the
calibration menu and return to the measurement
mode.
