1.Turn on pH meter
2.Immerse the electrode in pH 6.86 standard buffer solution
3.Press the "CAL" button.Wait until the display digital is 6.86pH.Then compelete pH6.86 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.Press"CAL"button.Wait until the digital is 4.00pH.Complete the pH 4.00 point calibration.
6.Clean electrode and dry it,put pH meter into pH9.18 standard buffer solution.Check if reading is correct between 9.17-9.19pH.
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.Press the "CAL" button long time in the air carelessly
pH electrode maintenance
If the electrode placed long time,and electrode exposed to air,then showing values is slow and not stable,because of electrode dry.You should immerse the electrode into water for few hours.
When the display value is fuzzy or unshown,the battery should be replaced promptly.Pay attention to the polarity of battery.
