Found it -- wrote a script to describe possible resistor dividers for measured voltages and one interpretation wins hands down over the other -- me happy. Computer as calculator, what a novel idea :) -5V to Vccp1 -12V to Vccp2 R1, R2 1200, 2700 1500, 8200 Assume R1 to +5V as Vref, R2 to Vminus. Self calibrate by using measured +5V to calculate Vminus, dunno if sensors does that, works for me. Match is within measurement resolution. Cheers, Grant.
