Three phase analyzer - meter.

3945 Power Quality Analyzers
I dont' have anything to do with this company - however I got an ad in the mail
at work -
Three phase hand held waveform and power quality analyzer. Looks very
interesting.
Pdf documents on-line.
# True RMS single-, two- and three-phase measurements at 256 samples/cycle,
plus DC
# Real-time color waveforms
# Easy-to-use on-screen setup
# True RMS voltage and current measurements
# Measures DC volts, amps and power
# Display and capture voltage, current and harmonics to the 50th order,
including direction in real time
# Phasor Diagram Display
# VA, VAR and W per phase and total
# KVAh, VARh and kWh
# Neutral current display for three-phase
# Transformer K-factor display
# Power Factor displacement PF display
# Captures up to 50 transients
# Short-term flicker display
# Phase unbalance (current and voltage)
# Harmonic Distortion (total and individual)
Looks good - I have not seen the price - suspect it is not hobby level.
