Instructions:
1. Remove the protective cover.
2. Touch the "ON/OFF" switch to turn on the power.
3. Put the electrode into the testing solution and shake it lightly and read the indicated value when the value is stable.
4. Touch the "HOLD" button to hold the current measurement. If you need to read, press the "HOLD" button again to automatically release the hold.
5. After use, press the switch, clean the electrode with distilled water, then put the protective cover.
Note:
1: There is a white crystal salt around the electrode. This is a normal phenomenon of ORP electrodes. If the electrode is submerged in clean water, the electrode will melt and disappear.
2:If you test the ORP value, it usually takes minutes to about 10 minutes. Wait for a stable and very slow jump, or read the displayed value as a measurement.
3:ORP and air indication are jumping. It is a normal phenomenon that there is no regular change.
4:After using, turn off the power and wash the electrode with pure water or distilled water, dry the water with soft tissue, then put on the protective cover.
