1.4 Dip the pH electrode into the pH7.00 (or 6.86, or 6.79) buffer solution, the end of the electrode must be completely
immersed into the calibration solution. Stir the sensor gently to create a homogenous solution.
1.5 Press ENTER key, “Calibration” indicator begins flashing. Wait for the measured value to stabilize, the display
shows “END”. The meter returns to measurement mode automatically. Calibration is completed.
MULTI-POINT CALIBRATION
2.1 Make sure to select the desired calibration point between two to five (2-5) in the setup menu. Three points
calibration is recommended as a default calibration option.
2.2 Repeat steps 1.2 to 1.5 above.
2.3 When the first calibration point is
completed, the display will show “CAL2”. The meter prompts you to continue with
second point calibration.
2.4 Rinse the pH electrode with distilled water. Dip the electrode into the next standard buffer solution (e.g., pH4.01).
The meter automatically senses the current calibration solution and begins calibrating. “Calibration” indicator
begins flashing.
