The “ ” along with “STIR” tag will be displayed and “WAIT” will blink on the
LCD until the reading is stable. When the reading is stable and close to the
selected buffer, the “CFM” tag will blink. Press CFM to confirm calibration.
The calibrated value is then displayed on the 1st LCD line and the third
expected buffer value on the 3rd LCD line.
After the second calibration point is confirmed, rinse and submerse the pH
electrode approximately 3 cm (1¼”) into the last buffer solution and stir
gently.
If necessary, press the ARROW keys to select a different buffer value.
The “ ” along with “STIR” tag will be displayed and “WAIT” will blink on the LCD
until the reading is stable.
When the reading is stable and close to the selected buffer, the “CFM” tag will
blink.
Press CFM to confirm calibration.
At the end of calibration the instrument displays “SAVING”, stores the
calibration value and returns to normal measurement mode.
The calibration sequence may be reduced to two buffer values or a single one.
Press CAL to return to measurement after the desired number of buffers.
Note
:
•
When performing a new calibration or adding to an existing calibration
the first calibration point will be treated as an offset. See page 33 for
details.
•
Press CAL after the first or second calibration point are confirmed and
the instrument will store the calibration data. Then it will return to
measurement mode.
•
If the value measured by the instrument is not close to the selected
buffer, “WRONG BUFFER” will blink. Check if the correct buffer has been
