All testers and adapters connected to a UUT possess electrical characteristics (properties) that may impact the test results in diverse ways. The Characteristics section allows users to accommodate intrinsic components within the tester, adapter setup, or product that may affect the final test data. Users may capture or edit compensation data for Resistance or Capacitance for the Analyzer and/or Adapter.
