Product details


Functional Features

◉ AC sampling detection: It can perform virtual load verification (three-phase standard source) or real load verification (clamp current measurement).
Transmitter detection: Detect the basic error, DC ripple, and response time (software required) measurement function of the power transmitter.
Harmonic output function: Three phase electricity can be loaded 2 to 21 times, and harmonics with adjustable amplitude/phase can be tested for harmonic impact.
◉ Value adjustment formula: It has adjustment formulas such as "fixed-point output, rotary encoder, step ratio", etc. The three-phase can be adjusted uniformly or separately.
◉ Phasor diagram display: Adjust the phase of three-phase electricity arbitrarily and visually display it in the form of a phasor diagram.
◉ Good human-machine function: equipped with a large LCD touch color screen, the measurement value is displayed intuitively, the operation is convenient, and the manual inspection gauge is easy.
Synchronization meter detection (optional): The fourth voltage output can detect the amplitude difference, phase difference, and frequency difference of the power synchronization meter.
◉ Electric energy meter detection (optional): equipped with standard electric energy pulse input/output ports, suitable for verifying single AC energy meters.
Professional software (optional): Full or semi automatic calibration of the inspected table, data recording, analysis, management, and certificate export.
