Applications
Measure for excessive current (tripping of circuit breakers) and other general measurements (such as level of current flow) in each circuit. Measure balance between phases, neutral current and frequency, and harmonic distortion.
Measure input current, crest factor, and harmonics for PC, copier, printer, and single phase UPS. Most electronic equipment loads are nonlinear due to their use of
