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 technicians the mechanical and electrical information they need to effectively evaluate motor performance.

• Measure key parameters on direct-on-line motors including torque, RPM, mechanical power and motor efficiency
• Perform dynamic motor analysis by plotting of motor derating factor against load according to NEMA/IEC guidelines
• Calculate mechanical power and efficiency without the need of mechanical sensors, just connect to the input conductors and you're ready to go
• Measure electrical power parameters such as voltage, current, power, apparent power, power factor, harmonic distortion and unbalance to identify characteristics that impact motor efficiency
• Identify power quality issues such as dips, swells, transients, harmonics and unbalance
• 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.)
• Waveform capture function captures 100/120 cycles (50/60 Hz) of each event detected event, in all modes, without set-up
• Automatic transient mode captures waveform data at 200 kS/s on all phases simultaneously up to 6 kV
• Fluke Connect® compatible* – view data locally on the instrument, via Fluke Connect mobile app and PowerLog 430-II desktop software
• Safety rated for industrial applications 600 V CAT IV/1000 V CAT III rated for use at the service entrance and downstream
