 FLU-438-II Power Quality and Motor Analyzer

The new Fluke 438-II Power Quality and Motor Analyzer adds key mechanical
measurement capabilities for electric motors to the advanced power quality
analysis functions of the Fluke 430 Series II Power Quality Analyzers. Quickly
and easily measure and analyze key electrical and mechanical performance
parameters such as power, harmonics, unbalance, motor speed, torque and
mechanical power without the need of mechanical sensors.

The ideal portable motor analysis test tool, the 438-II can help locate,
predict, prevent, and troubleshoot power quality problems in three-phase and
single-phase power distribution systems, while giving technicans the
mechanical and electrical information they need to effectively evaluate motor

o Measure key parameters on direct-on-line motors including torque, RPM,
mechanical power and motor efficiency
o Perform dynamic motor analysis by plotting of motor de-rating factor against
load according to NEMA guidelines
o Calculate mechanical power and efficiency without the need of mechanical
sensors, just connect to the input conductors and you're ready to go
o Measure electrical power parameters such as voltage, current, power,
apparent power, power factor, harmonic distortion and unbalance to identify
characteristics that impact motor efficiency
o Identify power quality issues such as dips, swells, transients, harmonics
and unbalance
o PowerWave data technology captures fast RMS data, and shows half-cycle
averages and waveforms to characterize electrical system dynamics (generator
start-ups, UPS switching etc.)
o Waveform capture function captures 100/120 cycles (50/60 Hz) of each event
detected event, in all modes, without set-up
o Automatic transient mode captures waveform data at 200 kS/s on all phases
simultaneously up to 6 kV.
