A high voltage isolation tester has a high voltage side and a low voltage side coupled to each other by isolation amplifiers so that the high and low voltage sides are electrically isolated from each other. The high voltage side includes positive and negative high voltage test inputs and a common test input. The high voltage side also includes a positive switched voltage divider network and a negative switched voltage divider network. The low voltage side includes a controller that automatically controls switching of the switched voltage divider networks to make voltage measurements of voltages at inputs of the isolation amplifiers. Outputs of the isolation amplifiers are coupled to inputs of an analog-to-digital converter and the digitized voltages are read from the analog-to-digital converter by the controller.
