  • Probes not included; for probe version, see 438-II
  • Measure key parameters on direct-on-line motors, including torque, RPM, mechanical power and motor efficiency
  • Perform dynamic motor analysis by plotting motor de-rating factor against load, according to NEMA guidelines
  • Calculate mechanical power and efficiency by connecting to input conductors; no need for mechanical sensors
  • 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 in all modes, without set-up
  • Automatic transient mode captures waveform data at 200 kS/s on all phases simultaneously, up to 6 kV

The Fluke 438-II/Basic Power Quality and Motor Analyzer adds key electric motor mechanical measurements to the Fluke-430-II Series Power Quality Analyzers. An electric motor converts electrical energy into rotational forces that is used to drive critical industrial rotating machines like pumps, compressors and fans. By analyzing the input power the Fluke 438IIBasic can calculate the mechanical forces transferred to the mechanical load, without having to use an inline force transducer. The new parameters that can be analyzed in addition to the power quality measurements are:

  • Mechanical Power (HP/ kW)
  • Torque (lb.ft/ Nm)
  • Speed (rpm)
  • Efficiency (%)
  • Total De-rating Factor (According to NEMA)

By specifying the motor rated specifications, the analyzer can be used to obtain readout of the actual measured performance compared to the rated performance making it possible to identify overload condition, impact of poor power quality or the motors efficiency. These measurements are all obtained while the motor is in-service with the added bonus of not requiring external force transducers be installed on the motor shaft.

The derating graph will plot the % load versus derating factor under operating conditions taking into account input power quality according to National Electrical Manufacturers Association (NEMA) guidelines. The derating curve is then used to determine if the motor is operating within its rated performance. Motors operating outside of their rated performance for extended periods of time can result in a reduced lifespan and repeated failures. The 438-II/Basic includes a Soft Carry Case, test lead set, battery, and CD-rom with PowerLog 430-II software and user documentation.
