FOUR, THREE OR TWO-POINT CALIBRATION

• 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.

ONE-POINT CALIBRATION

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.

• 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 fifth expected value on the

secondary LCD.

• 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 “READY” tag will be displayed and the

“CFM” tag will blink.

• Press CFM to confirm the fifth calibration point.

• The instrument stores the calibration value of the

fifth point and returns to normal measurement mode.
