OPERATION:

  1:  Remove the protective cap.

  2:  First clean the electrode with distilled water,and suck it with filter paper.

  3: turn on PH by "ON-OFF" switch located on the top of battery case.

  4: Immerse the PH meter electrode in solution up to the immersion level.

      Under no circumstances immerse above display level.

  5: Stir gently and wait for the reading to stabilize.

  6: After use,switch off it,use the distilled water clean the electrode and replace the protective cap.

PH calibration

 1: Immerse the electrode in PH 6.86(inder the temperature of 25°C), standard buffer solution 

     of phosphate,and gently shake the electrode.

 2: Regulate the trimmer with a screwdriver until the buffer solution valve corresponding to the 

     measurement temperature is obtained.

 3: Immerse the electrode in PH 4.01 or PH 9.18 the standard buffer solution of borax.

 4: After about one minute,until the buffer solution valve corresponding to the measurement  

     temperature is obtained.

Important

The instrument's Ph range must be recalibrated whenever.

The electrode has been used(laid) for long time from the last calibration.

The electrode has been used in particularly taxing conditions.

The utmost accuracy is required.

Bttery install is the dispaly of meter fades,to replace all the batteries,pull out the battery case and replace the batteries.Pay attention to teh polarity of battery.
