The Metrel 3122 single and 3-phase loop and RCD testers can be used for testing loop impedance, line impedance, RCD trip time, RCD trip current, voltage, frequency and phase rotation.
Results are clearly presented using unique LED Pass/Fail indicators, while the in-built memory provides 1900 recorded measurements. Unlike most other recording testers, details of tests can be recorded in a structured format, allowing users to ensure test data is still relevant when reports are created.
The 3122’s broad operating voltage range ensures the instrument can be used in a wide variety of environments. Distribution board lead sets, and single phase power outlet leads are provided to ensure the 3122 can be used on single phase or 3-phase installations.
