7.4 pH Calibration 

The instrument provides multi-point standard buffer solution calibration. You may 

decide how many points to calibrate the measurement system(up to 3-point). The 

principle is according to “Method of Least Squares”. Apply linear regression to 

calibration the electrode’s slope and zero point (Asy, Offset or Zero point). 

When calibrating a electrode, you may calibrate 1 to 3 point by any sequence to 

provide linear regression for mV and pH multi-calibration of a electrode, and to show 

the electrode’s slope and zero point(Asy, offset or Zero point) at 25

°

C. The electrode’s 

slope rate which is actual slope divided by theoretical slope and the sensitivity shows 

in percentage in the display. In addition, the display shows the linear regression 

determination coefficient, R2, of the electrode and buffer solution to provide you an 

estimation of an electrode’s regression suitability. According to different combination 

of standard buffers, the TECH, NIST, Any buffer solution calibration modes are 

provided. 

 

7.4.1 TECH mode (Up to 3-point calibration) 

   

 

The electrode is automatically calibrated according to pH value and temperature 

of TECH standard buffers. The range of zero point and slope of the electrode is also 

determined. If one of them is over the range, the display shows error message of 

zero point and slope failure. (See appendix Table 1, pH/temperature table of TECH 

standard buffers) 

       

7.4.2 NIST mode (Up to 3-point calibration) 

      The electrode is automatically calibrated according to pH value and temperature 

of NIST standard buffers. The range of zero point and slope of the electrode is also 

determined. If one of them is over the range, the display shows error message of 

zero point and slope failure. (See appendix Table 2, pH/temperature table of NIST 

standard buffers) 

 

7.4.3 Any mode (Up to 3-point calibration) 

      The electrode measures mV value of different standard solutions. According to 

theoretic slope and the temperature of standard solutions, the display shows a 

approximate pH value. Then, you can calibrate the electrode by freely adjust the pH 

value as those of the standard solutions’. There is not a zero point range failure 

determination by the instrument but only the slope range determination. If the slope 

is over the range, the display shows error message of slope failure.
