• The calibrated value will be displayed on the primary LCD and the

second expected buffer value on the secondary LCD.

• After the first calibration point is confirmed, submerse the pH

electrode and the temperature probe approximately 3 cm (1¼”) into

the second 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 “READY” tag will be displayed and the

“CFM” tag will blink.

• Press CFM to confirm calibration.

• The calibrated value is then displayed on the primary

LCD and the third expected buffer value on the

secondary LCD.

• After the second 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 “READY” tag will be displayed and the

“CFM” tag will blink.

• Press CFM to confirm calibration.

• The calibrated value is then displayed on the primary LCD and the

fourth expected value on the secondary LCD.

• 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.
