2. Immerse the electrode in PH6.86standard buffer solution.
(under the temperature of 25°C)
3. After digital stabilized, press the "shift" button for 5 seconds,
(the instrument comes into the automatic calibration Status ) .
Wait until the display digital is 6.86pH Then complete PH 6.86 point calibration
4. Clean the electrode with distilled water and dry it with filter paper.
Immerse the electrode in pH 4.00 standard buffer solution,
5. After digital stabilized, press "shift" button for 5 seconds.
Wait until the digital is 4.00 pH..Complete the ph 4.00 point calibration.
6 .Clean the electrode with distilled water and wipe clean the spare water.
Put the electrode in the PH 9.18 standard solution until the data stable,
The data will be 9.17pH----9.19pH. The data is in the range of allowable error.
7. This instrument calibration work is completed after all the steps.
The instrument need recalibrate in the following condition.
1.Long time no use or use very long time after calibration
2.The electrode is used Very frequently.
3. The testing accuracy requirement is very high.
4.Do not press the "shift" button long time in the air.Otherwise the meter need recalibrate.
