    Update to new firmware in profilux 4, add doser 2.1 slave and add kh director,
    Ph reading was off, wanted to re-calibrate but the calibration menu on ph sensor
    Is missing in profilux 4.

    please help.

    Thank

    If you are calibrating a pH probe that is connected to the P4, you should calibrate using the P4 touch keys.

    If you are trying to calibrate the KHD probe which should be connected to the KHD, you will see the option to calibrate this probe in the KH Director settings page.

    Hi Vinny,

    I’m using the profilux 4, first set up i can calibrate using the touch key.
    After upgrade to the latest firmware, the menu for calibration is not there.
    Ph showing ph-1 virtual in the myghl.

    Fyi i have profilux connect to 2x doser and connect to kh director.

    Thx.

    Hi,

    Can you please post a screenshot of your pH-1 settings page?
    Also include a screenshot of your SENSOR/PROBE controls list.

    Please do the following using the P4 touch keys:

    Press up or down arrow key and select Sensor settings
    How many pH sensors do you see listed?

    NEXT

    Press up or down arrow key and select SYSTEM, then select VIRTUAL PROBES.
    Do you see an option to delete a virtual probe?

    Please answer these questions before proceeding any further.

    Yes, please do.

    Let us know if you are able to see the original pH probe after deleting the virtual probe.
    Please check using the app and also GCC.
