Calibration:

1. Turn on the PH meter

2. Immerse the electrode in PH 6.86 standard 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 is in the range of allowable error.
