Re: about to throw VR3 brick away OK, done all stages and millivolt reading does not change. Once unit is calibrated to 98% and I breath off the loop the reading does not change. either port is stuck on vr3 or cell has gone very wrong. so...I changed the cell and no change, still gives me the exact same mV rating, surely that can't be correct.
Going to give up for this evening and try again tomorrow.
