TH3300 series digital power meter for AC and DC power tester, using PLL phase-locked loop technology to achieve fast synchronization of sampling, synchronization source provides a signal source and power supply options, the use of power supply synchronization can be established all the time to lock without the use of a signal source mode of voltage and current switching, frequent loss of locks, locking process, you can provide a faster test speed; at the same time, for low-frequency signals to provide a fast measurement.
The TH3300 series of digital power meters cover a wide range of current testing, from a few microamps to 40 Arms, and can measure input signals that include AC and DC components. Measurement applications range from small currents for standby power consumption to large currents for induction cookers;
TH3300 series digital power meter with high frequency test range and wide frequency response, provide harmonic analysis and a variety of harmonic data display (list, column, etc.); provide measurement of the input signal waveform display (voltage and current at the same time or separate display).
TH3300 series digital power meter adopts a small chassis design, easy to rack mounting; equipped with 4.3-inch LCD screen display, test functions and measurement parameters are more abundant, and provides two display style interface: digital tube of the four-window display; full-parameter full-screen display.
