Hi ive received my new p4 today , ive gone to calibrate the conductivity sensor and it keeps calibrating the 50ms soloution to 47ms , i am making sure the 50ms soloution is 25c and ive even tried another conductivy sensor but it keeps reading the 50ms at 47ms , can anyone shed some light on the please. Thankyou.

Can you please outline the steps you are taking during the calibration process?

When you are asked to select: Temp.-Sensor 1 OR Aquar.temp.man. - What are you selecting?

Are you using the Conductivity calibration steps provided on page 54 of the P4 Programming Manual?

How old is the 50mS fluid?
