Hi Folks,
I know what you're thinking, another salinity probe going nuts...
Well, not exactly. My probe is actually very consistent. It's just it's wrong! Salinity is a stable 35ppt according to properly calibrated refractometer and verified with a Milwalkee.
The probe has been calibrated several times, but still shows this level. There are no air bubbles and turning upside down, shaking etc has had no effect.
The salinity probe is connected to the PM2 module, mounted in the sump next to the temperature sensor. The changes shown are the ATU, which tops up into the same chamber as the probe.
How should I best adjust the probe to show the actual salinity?
