That's what calibration is about! When you have shaken the probe up and down a few time and wait for the value to stabilize, you can press the left button to confirm to the next calibration step. After you have completed the calibration, you can test the accuracy again in the ph calibration solution.
Just seen all the videos on this will certainly be trying one on my channel when I can afford one great bit of kit 👍
Hola, para que funciona la opcion de PH-Adj tengo esa duda respecto a la calibración
Hello,
What to do if the reading doesn't match the solution ph during calibration process?

Are you mixed Rodi water with ph solution before you do calibration?
@@khoatruong-r5q You can use pure water or distilled water. However, RODI water cannot be used to equip the calibration solution.
