P3 Conductivity probe: 0.8ms ?

[Gilles]

I have a freshwater conductivity probe (2 black rods at the end, no glass). If i have the correct electrode, can it be that i have <1ms conductivity in my tank?
Just calibrated it to be sure with 50ms and all went very fast (meaning electrode is oke)

I am sure i have connected it to the right port; and i put the 'blind' connector on the redox port.

if we are talking about freshwater then it must be calibrated with a fluid 1ms ... 2ms (= 1000uS ... 2000uS)

ensure that correct measurement range is enabled (P3eX: software setting, Expansion Box: switch)

my tank has a value of approx. 500uS

Ah thank you! I could only enter "50ms" so i think i have the wrong setting. I'll check.
