1, Product introduction
This instrument is a multi-functional, high-precision, intelligent and hand-held measuring instrument designed for on-site measurement of voltage, current, power, power factor, frequency and phase. It is widely used in electric energy metering, power consumption inspection, power inspection, meter installation, power connection and relay protection, differential detection, startup test, railway electrification, industrial and mining enterprises, scientific research institutions and other departments.
The software uses a high-speed Cortex M3 processor and 24 bit high-speed ADC to measure and calculate the electrical parameters, with a fully graphical interface and a true color display resolution of 320 × 240. Touch screen operation has a friendly man-machine interface and is convenient to carry.
2, Functional features
1) 3.2 inch TFT color touch LCD screen, rich in color, flexible touch control menu.
2) At the same time, measure three-phase voltage and four circuits of current (including zero line current).
3) At the same time, measure the three-phase AC voltage phase angle, current phase angle and power angle.
4) Measurement of active power, reactive power, apparent power, three-phase power and power factor.
5) Measure the grid frequency and phase sequence.
6) Automatic identification of load type (resistance, inductance, capacitance)
7) Hexagonal vector display can visually analyze the phase relationship of voltage and current of each phase.
8) It is compatible with single-phase, three-phase three wire and three-phase four wire test methods.
9) Intelligent design to prevent misoperation, with high accuracy, high stability, low power consumption, easy to use and other advantages.
10) The voltage transformer and current clamp are used for input. There is no high voltage in the machine. The two inputs are completely isolated, safe and reliable.
11) High precision current clamp is used for current measurement. The magnetic conductive material is high-grade permalloy, which has high permeability under weak magnetic field. The measurement accuracy and stability are superior to those of ordinary materials in the market.
12) The test line adopts special power cable, and the spring rod plug and alligator clip have insulation protection.
13) With data storage and query functions; Press the HOLD key to save the data statically.
14) Built in lithium battery, low power consumption, can be recharged repeatedly, and the standby time for one charge is more than 20h. Real time display of battery power.
The power switch of the instrument adopts long-life membrane touch button and one button switch.
