No electrical installation safety tester, single function or multifunctional, is complete without appropriate accessories. We are not talking only about trivial ones like the test leads, probes, crocodile clips and other essentials, but specialized adapters for expanding measuring ranges of connected electrical installation safety testers or for enabling new test and measurement functionalities.
Metrel has developed adapters for automated testing of 3-phase electrical systems, for testing automatic trip out protection in high-voltage equipment using high current and even a dedicated adapter for testing proper functioning and safety of portable RCD devices. Last but not least are adapters for comprehensive testing of electric vehicle supply equipment (EVSE).
