The Norma High Precision Power Analyzers
deliver precise measurements of single or
three-phase current and voltage as well
as calculation of power and other derived
values. They provides class-leading
accuracy for any waveform, frequency or
phase shift. Its 144 mm (5.7 in) color display
makes it easy to use both in the field and as
a table unit in labs and on test benches.
