Product overview: Fluke 438-II motor efficiency and electrical performance comprehensive tester

438-ii is the ideal portable motor analysis and testing tool to help you locate, predict, prevent and eliminate power quality problems in three-phase and single-phase power distribution systems, while providing technicians with the required electromechanical information to effectively evaluate motor performance.

Measure the key parameters of direct start motor, including torque, speed, mechanical power and motor efficiency

Draw the motor derating coefficient and load comparison diagram (according to NEMA/IEC criterion) to perform dynamic motor analysis

To calculate the power and efficiency of machinery, no mechanical sensors are needed, only input wires are connected, and everything is ready

Voltage, current, power, apparent power, power coefficient, harmonic distortion and unbalance are measured to determine the characteristics that affect the motor efficiency

Identify transient, transient, transient, harmonic and unbalanced power quality problems

PowerWave data technology captures rapidly changing RMS data, displays half-cycle averages and waveforms to describe the dynamic characteristics of the electrical system (generator starting, UPS switching, and so on).

Waveform capture captures 100/120 cycles (50/60 Hz) for each detected event in all modes without setting

Automatic transient mode can capture 200 kS/s waveform data at the same time on all phases when the voltage is up to 6 kV

Compatible with Fluke Connect ® * - by instruments to check the data locally, by Fluke Connect applications and PowerLog 430 - II desktop software to check the data

Safety rating for industrial applications: 600 V CAT IV/1000 V CAT III for indoor and downstream use
