TH3422 4-Channel Power Meter with Waveform & Harmonic Analysis
AC/DC Power Meters typically feature a clear and easy-to-read display that shows the measured parameters in real-time. The display may include digital readouts, bar graphs, and waveform displays for comprehensive visualization. Additionally, advanced power meters allow for data logging, where measurement values can be recorded and stored for later analysis. This feature is particularly useful for monitoring power usage over time, identifying peak loads, and assessing the efficiency of electrical systems.
Features
Channel combination: optional 3/4 channels
AC and DC test
High stability and consistency: adopt phase-locked loop frequency multiplication synchronization control and power synchronization setting
