how do i calibrate a ph probe for the first time

[plankton]

I had a p2 which i upgraded to a p3. I now want to attach my ph probe for the first time. How do I do this? How do I calibrate. I have calibrations fluids ph 7 and ph 9.

Specific instuctions of calibration via software (not hardware) would be great.

Also, should i rinse the probe between switching from ph7 to ph9 so I do not contaminate the calibration fluid?

Initializing of calibration process is possible only directly at the controller. A way to avoid that is to use remote control of PLC

Thats self-evident. And you shuld not use the containers with test fluid itself. Use a test tube with a small amount of test fluid and thow it away after calibration.
In between the test fluids clean with demineralized water (or fresh water if you don´t have)
