I have seen this on my last 3 MX60 controllers and it is very frustrating and
looks to be a design flaw. I can calibrate the meters to be accurate at either
the Absorb point OR the Float point but NOT both!! Not only that but the meter
calibrations tend to drift a bit in just a matter of days, just .1V not a big
deal but anymore than that on a 12V sealed battery and it could be an issue. I
spoke w/Outback about this and heard a mumbled "Ahh, uummm, yeah that is an
issue". I'm guessing that you're seeing the same thing and when you spoke
w/your customer again and the meters all agreed I'll bet it is because the MX
was at the "line up point" of the other meters (just like a broken clock being
correct twice a day!). The only way to live with this is to get the more
important Absorb set point right on and take what you get on the lower end. It
works and is usable but drives customers nuts when they have additional meters.
In my experience the Tri-mets are dead on.
