• 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 buffer 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.
• 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 buffer 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.
