key twice. The secondary
display will change to “7.01”.
• When the electrode is submerged in the

user the reading is not stable.
If the readings fluctuate the
LCD will blink “NOT

stable, “READY” and “CON”
will blink.

firm the calibration. If the
reading is not close to the
selected buffer, “WRONG

”
and “WRONG ” will blink al-
ternatively. If the reading is
close to the selected buffer
the meter stores the read-
ing (and adjust the offset
point). The buffer value is
than displayed on the pri-
mary LCD and the second-
ary LCD will display “4.01”.
• Press the CAL key and the
calibration process is ended
with only the offset of the
meter calibrated.
For best accuracy however, it is recommended
that a two point calibration is performed (see
page 19).
