2.4 When the reading has stabilized, the display will show ---/CAL3.
The meter prompts you to continue with third point calibration.
2.5 Repeat the step 2.3 above until the meter shows .
Calibration is completed.
pH Calibration with Custom Buffers
3.1 Ensure that you have selected the option in the setup
menu, the custom buffer solutions should be at least 1 pH unit
apart from each other.
3.2 Rinse the pH electrode with distilled water, place the electrode
(and temperature probe) into the buffer solution, stir gently and
wait until the measurement is stable.
3.3 Press the Cal key, the meter enters the calibration mode.
3.4 If necessary, press the / key to set the calibration value,
press the Enter key to begin the calibration.
3.5 When the reading has stabilized, the display will show CAL2. The
meter prompts you to continue with second point calibration.
3.6 Repeat the steps 3.2 and 3.4 above until the meter shows .
Calibration is completed.
• During the calibration, if the display shows ---- indicating the
meter is waiting for recognizing the pH buffer solution.
• If the display shows indicating the measured mV value for
the current calibration point deviates by more than 60 mV from
the theoretical value of the pH buffer. The calibration will not be
accepted. Please check the pH electrode and buffer solutions.
• If the calculated electrode slope is not between 70% to 110%,
icon will disappear from the display. The pH electrode
may need to be replaced.
• To exit the calibration without saving changes, press the Meas
key.
