  1. I do not understand the algorithm being used for reporting "resistor too high!?" in the impedance analyzer. It seems to pop up whenever the phase is close to 0°, which makes no sense to me. The resistor is too large when the magnitude of impedance measured is less than about 0.01 times the reference resistance—the phase isn't really a relevant parameter. A slightly more sophisticated algorithm might look at the voltages of the two measurements and report the resistance being too large or too small when the relevant voltage (across the resistor or across the DUT) gets down to only a few
