The MT-1/NT3 can be set to test all 3 phases simultaneously in one step or set to do a full test consisting of the 3 phases simultaneously followed by each element separately.
An ideal testing solution for self-contained meters, the MT-1/NT3 also has reverse flow testing capability for net metering installations.
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.
