The perfect tool for tracking down single-phase
power -related problems
The Fluke Model 43B Power Quality Analyzer performs the measurements you
need to maintain power systems, troubleshoot power problems and
diagnose equipment failures. The new Model 43B has 20 storage locations
and can store data as well as screens.

|
|
- NiMH Battery provides extended operating time
of 6.5 hours.
- Combines the most useful capabilities of a
power quality analyzer, multimeter and oscilloscope.
- 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.
- User/applications manual and power quality
video to help answer tough questions.
- Complete package with voltage probes and 400A
current clamp, FlukeView Software and optically isolated interface
cable.
- 3-year warranty on the 43B and 1-year on the
accessories.
