Verification of Safety Testers: A Better Approach (774.84 KB)

In the past, it has been a challenge for metrologists to properly verify electrical testers’ performance, especially for those testers with high voltages, high currents and extreme resistance measurement capability. This application note describes the functionality of some of the electrical testers, and discusses requirements to verify their performance. It also covers an improved method of verifying many of these devices and the challenges the design engineers faced when building these techniques into a new calibrator.
