Abstract
Exemplary methodologies and apparatuses for testing and calibrating small-signal battery testers are provided. An exemplary apparatus includes one or more capacitors electrically coupled to one or more conductive elements, and a power supply. The one or more conductive elements include one or more connection points for connecting the small-signal battery tester. The one or more connection points are arranged to arrange the selection of one or more impedance, conductance, resistance or admittance values that can be used to test or calibrate or test a small-signal battery tester.

24. A method for evaluating a small-signal electronic battery tester comprising:
-
charging a capacitance with an associated known parameter between nodes;
producing a test value by operation of a small-signal electronic battery tester between the nodes;
determining whether the small-signal electronic battery tester is in calibration as a function of the test value and the known parameter between the nodes; and
calibrating the small-signal electronic battery tester if it is not in calibration. - View Dependent Claims (25, 26, 27)
