Choose ‘pH (2 points) 4/6/9’ (Before each operation, the electrode can be placed in the standard solution for about 60s)
After calibration of 1st point, follow with the 2nd point:
After above calibration, there will be the results:
Calibration 6.86 and 4.00 will be saved in offset 1 and slope 1; calibration 6.86 and 9.18 will be saved in offset 2 and slope 2.
Save the results and it can be queried next time.
The pH value of the buffer is measured at 25 °C, please select the correct buffer
(please refer to P30 “Buffer Table”).
Before calibration, the electrode can be activated by soaking in the solution to ensure
the stability and accuracy of the calibration value and the detection value.
Calibration with Standard Liquid (pH, 3 points)
There are two groups of 3-point standard liquid USA: 4.01, 7.01, 10.01 and NIST:
4.00, 6.86, 9.18, The following example uses the NIST standard solution set:
Choose pH standard liquid, press
