PH Expansion High

Post by stevengreen2 »

I got the PH Expansion today and set it up but whether I use the probe that came with the unit that is working fine or the new probe in to the expansion unit it reads 1 point high.

You need to calibrate the module to the probe you will be using it.
Not all probes are made the same and that is the reason for calibration.
Everytime you change probes, you will need to recalibrate.
