1. Power on the meter
2. Place the electrode into a buffer solution
(4,7or10), pH7 should be calibrated first
and then 4 or 10 pH for better accuracy
3. Press " " (8681/8682) or " "
(8680) to enter pH calibration mode.
The text "CA"( or CAL, only for 8682)
will appear on the LCD for one second
(Fig.E) and then text "CAL" and solution
pH value (4,7 or 10) will be displayed on
the LCD. (Fig. F&G)
Calibration is necessary and should be
done regularly, recommend everyday if
the meter is used often. The unique
calibration design of the meter features
automatic buffer recognition to avoid errors.
