Main functions and features

Adopting a 3.2-inch 320 × 240 true color TFT LCD screen, the GUI (graphical user interface) adopts enwin design, with a beautiful and elegant interface and easy operation.
Current: 10A current clamp, capable of measuring angle values with a minimum of 0.3mA; Voltage: A minimum of 1V can measure the angle value. Convenient for various light load or transformer no-load operation scenarios.
When measuring the phase between U1-U2, the two input circuits are insulated and isolated, thus avoiding possible misconnections that may cause short circuits in the measured circuit and burn out the measuring instrument.
The reference signal of a vector graph can be flexibly and automatically selected for drawing based on the presence or absence of the signal.
The display modes of the vector diagram include metering mode and relay protection mode, and the phase display range is 0 ° -360 ° and -180 ° -180 °, which is convenient for users with different habits and can intelligently distinguish the wiring results and phase sequence of 48 types of three-phase three wire metering devices.
Multiple range current clamps can be equipped.
The range of voltage and current signals is automatically selected without manual operation, making it easy to use.
It can determine the capacitance and inductance of a circuit, and calculate parameters such as resistance, reactance, conductance, and susceptance.
Real time display of voltage and current waveforms, and measurement of waveform distortion.
It can display the 2-57th harmonic content and bar chart, and has the function of power quality analysis.
By setting PT and CT, the secondary side data can be converted to the primary side, displaying the voltage, current, power, etc. of the primary side.
The phase measurement data is averaged, and the data display is stable without any abnormal display of data at the 0 ° and 360 ° critical points.
Can simultaneously measure 4 input signals (2 voltage, 2 current).
It can display the true effective value, phase, power, power factor and other electrical parameters of voltage and current. The measurement results are displayed in various ways such as vector diagram, effective value, phase, power, etc.
Based on the tested electrical parameters, it is possible to determine the wiring group and inductive capacitive load of the transformer, test the secondary circuit and bus differential protection system, read out the phase relationship between the CT of each differential protection group, and check whether the wiring of the energy meter is correct.
Built in Flash memory, the instrument can be seen as a USB flash drive. It can store 10000 sets of measurement data and view them on the instrument.
Built in high-energy lithium-ion battery, long lifespan, convenient to use.
