Remove the protective cover. 2. Touch the “ON/OFF” switch to turn on the power. 3. 4.Immerse the electrode in the test solution, shake it gently, and read it after the displayed value has stabilized. 4. Touch the “HOLD” button to hold the current measurement value. If re-measurement is necessary, press the "HOLD" button again and the hold state will be automatically released. 5. After use, please press the switch, wash the electrode with distilled water, and cover with the protective cover. ORP electrode. Just soak the electrode in clean water and it will melt and disappear. 2: Measuring the ORP value usually takes a few minutes to 10 minutes. Wait for the value to stabilize and jump slowly, or read the displayed value as a measurement. 3: ORP and air display values are jumping. It is a normal phenomenon that there are no regular changes. 4: After use, please turn off the power, clean the electrode with pure or distilled water, dry the water using a soft tissue, and wear the protective cover. package list
