Operation

1.remove  the  protective cap.
2.first rinse the electrode with distilled water, and suck it with filter paper.
3.turn the meter on by pressing the "ON" key.
4.immerse the ph meter electrode in the solution to be tested(can not be 
over the immersion line )
5.stir gently and wait around 30 seconds till  the reading stabilized.
6.after finished ,clear the electrode with pure water ,turn the meter off  by  
pressing the "ON/OFF" key.
7.Always replace the protective cap after use.
 

Calibration.
1. Turn on  pH meter
2.Immerse the electrode in pH 6.86 standard buffer solution.
   (under the temperature of 25°C)
3. Press the "CAL" button.
  Wait until the display digital is 6.86pH Then complete pH 6.86 calibration
  Clean the electrode with distilled water and dry it with filter paper. 
4.Immerse the electrode in pH 4.00 standard buffer solution, 
  Press "CAL" button.
  Wait until the digital is 4.00 pH..Complete the pH 4.00 point calibration.
5.Clean electrode and dry it , put pH meter into pH 9.18 standard buffer solution.
 Check if reading is correct between 9.17-9.19pH.
 
 Attention
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.
