• After the third calibration point is confirmed, submerse the pH electrode
and the temperature probe approximately 3 cm (1¼”) into the next
buffer solution and stir gently. The temperature probe should be
close to the pH electrode.
• If necessary, press the ARROW keys to select a different buffer value.
• The “ ” tag 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.
• After the fourth calibration point is confirmed,
submerse the pH electrode and the temperature
probe approximately 3 cm (1¼”) into the next
buffer solution and stir gently. The temperature probe should be
close to the pH electrode.
• If necessary, press the ARROW keys to select a different buffer value.
• The “ ” tag 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 instrument stores the calibration value
and returns to normal measurement mode.

• Proceed as described in “FIVE-POINT CALIBRATION” section.
• Press CAL after the fourth, third or second calibration point was
confirmed. The instrument will memorize the calibration data and
return to measurement mode.

Two SETUP selectable options are available: “Pnt” and “OFFS”.
If the “Pnt” option is selected, the new calibration point overrides an
existing one. The adjacent slopes will be reevaluated.
If the “OFFS” option is selected, an electrode offset correction is performed.
The adjacent slopes will remain unchanged.
• Proceed as described in “FOUR, THREE or TWO-POINT CALIBRATION”
section.
• Press CAL after the first calibration point was confirmed. The
instrument will memorize the one-point calibration data and return
to measurement mode.
