Portable Single-Phase Watthour Meter Tester
With the commercial 12S meter, the MT1/NT4 can test two phases simultaneously or separately. The meter under test is entirely controlled by the test socket. No setup wiring is needed.
With its specific purpose, the NT4 is the most affordable testing solution for most common single-phase form meters.
Three built-in 50A current synthesizers (phantom load) simulate active and reactive load.
Its built-in single-phase Wh/VARh standard will offer you a typical NIST traceable accuracy of ±0.02%.
Fast setup with no wiring and a dead-front design means your operation is quicker and safer.
Setting-up your test has never been easier.
