i manualen står der lidt om callibrering af sættet, men efter som der ingen vædske er med, skrev jeg fluks til AM. for at høre om det var en fejl eller hvad..jeg fik dette svar : Measure the density of your water. Afterwards measure the conductivity. The result is your setpoint. It will be between 40 and 60 mS/cm. If you want to calibrate the LF-Controller later again. Prepare fresh saltwater (but you must use the salt from the same manufacturer) with the density you have used for the first check and measure the conductivity. If it is different, calibrate.
Spørgsmålet er kort sagt : Hvordan måles density i vand ??
