1. You can first set the meter per your request. Otherwise, the setting will be factory defaults.
2. Use tap water or distilled water to clean the pH and the temperature electrode, removing the
adhesive impurities on the surface of electrode.
3. After power on, press to select the operation mode (pH, mV or Ion).
4. Immerse the pH and the temperature electrode in the solution and stir gently. The measuring
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.
5.6 Measurement Mode
