ed waveforms where
most clamp-on meters fail.
Typical measurement environ-
ments include office equipment,
high intensity discharge lights,
variable speed drives and most
all other electronic equipment.
The Model F3N also measures
Min/Max values and Peak values
to 1000A for Crest Factor
calculations an indication of
harmonic content. Both models
measure Frequency, which is
used to detect 3rd order
harmonics (180Hz in 60Hz
systems), set generator
governor speed, or check output
frequency on adjustable speed
drives. The Models F1N and
F3N are very rugged and
designed to withstand daily
professional use.
