How to use?
? STEP 1: Turn open pH meter, Clean the electrode in distill water
? STEP 2: Immerse the electrode in pH 6.86 standard buffer solution
? STEP 3: Press the "CAL" button. Wait until the display digital is 6.86pH and steady
? STEP 4: Clean the electrode in distill water and dry it, immerse the electrode in Ph 4.00 standard buffer solution
? STEP 5: Press the "CAL" button. Wait until the display digital is 4.00pH. Then complete pH 4.00 calibration
? STEP 6: Clean electrode and dry it, put the meter into PH 9.18 standard buffer solution. Check if reading is correct between 9.17-9.19pH

Operating steps:
1. Take down the protective jacket of PH meter
2. Use distilled water to clean up the electrode of PH meter, and then use filter paper to soaks up the water of electrode
3. Switch on the switch which on the battery compartment
4. Insert the PH meter into solution until the liquid submerge the "immersion line"
5. Slightly stir resolution for about two minutes and you can read the displayed value
6. After use, clean up the electrode, turn off switch and put on the protective jacket of PH meter

Note:
1. The instrument is a professional instrument, please under professionals instructions in order to avoid instrument failure
2. Avoid heat, direct sunlight
3. Please adopting standard buffer solution calibration, incorrect calibration would cause measurement error, thus affecting the accuracy of the test solution, or cause the instrument not working properly.
4. Do not thrown the instrument into the test solution to avoid the circuit board short circuit.
