Step:
1. Remove the protective cover.
2. Press the "ON/OFF" switch to turn on the power.
3. Put the electrode into the solution to test the electrode, shake gently, and read the indicated value after the value is stable.
4. Press the "HOLD" button to hold the current measurement. If you need to read, press the "HOLD" button again to automatically release the pending state.
5. After use, press the switch to wash the electrode with distilled water and cover the protective cover.

Note:
1: There is a white crystal salt around the electrode, which is a normal phenomenon of the ORP electrode. Only when the electrode is submerged in clean water, it will dissolve and disappear.
2: When testing ORP value, it usually takes about minutes to about 10 minutes. The value is stable and very slow jump, or wait to read the displayed value as measurement.
3: The ORP and air display values are jumping, which is normal in no regular change.
4:After use,turn off the power and clean the electrode with pure water or distilled water, dry with soft tissue paper and protect the cover
