When you take the KCl conditioning vial of the pH probe, you have to hold the clear vial part and twist the white part anti-clockwise, therefore the vile will be gently released. When you finish analysis put it back on and twist it clockwise direction to seal it.

at 2:05 you don't have to pull out the probe from the 3M KCL soaking tube. Simply rotate the upper flexible screw of the soaking tube and the probe will come out itself without any forced rotation of the soaking tube from the bottom. Else it may damage the probe bulb in process.

Seriously do you think you did it right? You calibrated your instrument by standard buffer 4.01, followed by 9.21 and finally by 7.00. And after calibration you pressed exit button without even pressing END button hence not saving your calibration into your instrument. Consequently no slope can be displayed by your instrument since you didn't even ended your calibration and saved it. Correct me if I am wrong if you disagree.

On the other hand, at the main display, the machine in Router mode, i can't calibration the group buffer 4, 7, 9.21 because this machine mesure not exactly. Can you help me the method to this machine return as originally, when i press menu structure of pH/ion have 7 mode. Thank you!!
