Patent applied for.
Accuracy: For R, L, and C: +/- 0.2% of reading in basic ranges, if quadrature
component is small (D < 0.1, Q > 10, etc). See table. D accuracy: +/- .001 in basic
ranges, for D < 0.1 (otherwise, see table). Q accuracy: +/-.01 in basic ranges, for Q < 1
(otherwise, see table).
Ranges: Pushbutton selection with automatic front-panel guidance. Three basic ranges
(best accuracy, see table) of 2 decades each, for each parameter. Automatic extensions
to min and max, as tabulated.
