Conductivity calibration is not an option - card or firmware problem?

[Larskn]

My 3.1A ex is running perfectly with all its' 6 level sensors. My conductivity probes are both active and showing sensible measurements, but still I don't get to calibrate. Is it a card or a firmwareproblem - or something else?

[Gunther]

Calibration is only possible directly at the PL
There is no way to do it with GHL Control Center or web interface (except remote control of te PL)

[Larskn]

Thanks for your reply, Gunther. The issue is that "Calibrate" does not show up at all in the "Sensor Settings" menu on the Profilux itself. Probably this is due to a faulty ex-card or there is some bug in the software? Or something else?

[GHL Support]

In order that the calibration shows up in the menu, the following must be fulfilled:

-the conductivity measurement must be active
-the sensor must be in a proper condition (e.g. no broken cable)
-the sensor must be connected

Larskn, I have experienced this as well ... it was there, then it disappeared, and then it came back ... it is a mystery. Have you tried to engage it through a reboot?
