-It is advised to calibrate the meter with electrode using buffers that cover or are near to the measurements to be performed and/or to be acquired. Use at least 2 buffers or more when measuring in a larger pH range.+It is advised to calibrate the meter with the electrode using buffers that cover or are near to the measurements to be performed and/or to be acquired. Use at least 2 buffers or more when measuring in a larger pH range.
  
 Check the accuracy of the pH buffers to know the possible measurement errors. Measuring between 2 buffers, used for the calibration, with an accuracy of 0.02 pH will introduce a measurement error of 0.04 pH. Check the accuracy of the pH buffers to know the possible measurement errors.
