First of last memory clear after performed calibration.in ph calibration we have used to 5 buffer solutions.First we used to calibrate ph meter we use solution of ph 1 buffer solution and it's ph is around 0.95 to 1.05 , after ph 4 buffer solution ,ph 7 buffer solution ,ph 9 buffer solution, ph 12 solution. And it's slope is 90 to 105 % . After we have to do verification. And the verification is to do disending order. Because we conformed that our calibration is completed.
