The Fluke 43 Power Quality Analyzer performs
the measurements you need to maintain power
systems, troubleshoot power problems and
diagnose equipment failures. All in a rugged
handheld package.
Features
New! NiMH Battery provides extended
operating time of 6.5 hours
Combines the most useful capabilities of a
power quality analyzer, multimeter and scope
Calculates 3-phase power on balanced loads,
from a single-phase measurement
Trends voltage, current, frequency, power
harmonics and captures voltage sags,
transients and inrush current
Monitoring functions help track intermittent
problems and power system performance
Records two selectable parameters for up
to 16 days
20 measurement memories to save/recall
screens and data with cursor readings
FlukeView® software can log harmonics
and all other readings over time and provides
a complete harmonics profile up to the
51st harmonic
Measures resistance, diode voltage drop,
continuity, and capacitance
Users/applications manual and power quality
video to help answer tough questions
Complete package with voltage probes and
400 A current clamp, FlukeView Software and
optically isolated interface cable
3 year warranty on the Fluke 43B, 1 year on accessories
Harmonics
