1. Dip the sensor into the already set buffer solution when in pH calibration mode. For details,

please refer to the standard solution setting.

2. Press key to enter pH calibration step. “ ” will be displayed. Dip the sensor into buffer

solution(7.00 or 6.86 pH). When the value is stable and display “ ” together with the twinkling

stops,indicates the first zero point calibration is completed. Screen blanks for 2 seconds for saving

the data. Then the meter will automatically go to second point calibration. Dip the sensor into the

second buffer solution. When the value is stable and display “ ” together with the twinkling stops,

indicates the second point calibration is completed. You can go next to third point calibration or

fourth point calibration. You can also press key go back to measurement mode. (To check

the calibration results: long press for 3 seconds)

Note: During the calibration process, you can also press key to terminate calibration process

and back to measurement mode. Calibrated points are already saved.

If “ Err ” shows when in calibration, could be the following reasons:

1.Wrong buffer solution. First point defaults as Zero point calibration. Please follow the Auto Buffer
recognition order.

2.Poor performance of electrode.

3. Stabilized time is more than 30 seconds.

4. After calibration, in measurement mode, if”%” is continuous twinkling, means the sensor slope is
below 65%. Please timely maintain the electrode or change electrode. Then re-calibrate.

mark will twinkle. You can read the value once the data is stabilized and shows the stable

mark . When sensor slope is below 65%, slope will twinkle, please timely maintain the electrode

or change electrode.

1. When the screen shows “ATC” means the temperature sensor is working and shows the actual

temperature upper right corner. You can refer to the P-02 “Temperature Offset setting” if a revision

on the temperature is required.

2.If “ATC” is not shown on the screen means the temperature electrode is disconnected

and is manual temperature compensation. Factory default is 25°C. You can refer to “

Manual temperature setting” to adjust the temperature.

3. The measuring value is stabilized when the screen showed , The is showed if the Auto

Lock Function is on. Press to unlock.
