Wasites WT802 high-precision AC and DC parameter Measurement Instrument, Voltage, current Power Power factor Frequency

The electrical parameter Tester uses high-speed CPU for data processing, and the Voltage adopts low-temperature drift resistance and electricityThe stream is sampled with high-precision four-wire resistance, so that the sampled signal is not filtered, and the measurement data is guaranteedstability and accuracy. It has true rms (RMS) measurement and can accommodate full-wave, half-wave (AC-straightening).Flow pattern), non-specification waveform and other occasions of electrical parameter measurement. This instrument can measure Voltage (V) and electricityFlow (A), active power (W), power factor PF, frequency Hz and other parameters. The instrument has a perfect functionIt has the characteristics of superior performance and simple operation, which can meet the high-speed measurement of the production site and can also be fullFoot laboratory and R&D measurement needs.

It is widely used in lighting appliances, power tools, household appliances, motors, electric heating appliances and other collarsProduction lines, laboratories, and quality inspection departments of production enterprises.

According to the actual needs of the user, a variety of measurement functions can be customized to meet higher applications.

peculiarity

• Four-window 5-digit LEDs simultaneously display Voltage, current, power, power factor/frequency

• The 32-bit MCU design makes the measurement more accurate, faster and more stable

Principle

As shown in the figure, the instrument consists of an analog part and a digital part. The analog part is mainly composed of sensingdevice, multi-gear programmable amplifier, sampling and holder, A/D and other circuits. The numerical part contains micrometersIt consists of a computer data memory, a keyboard, and a monitor.

After the measured Voltage signal passes through the Voltage sensor, the signal is reduced to a weak signal, and the signal is largeSmall, controlled by a microcomputer, programmable multi-range amplification, and by a sample-holder, byThe analog/digital converter A/D converts the Voltage signal into a digital signal and transmits the digital signal to the miniatureThe computer calculates the true RMS Voltage (URMS) and outputs the value to the display on the display.

After the measured current signal passes through the current sensor, the signal is converted into a weak Voltage signal, which is the same as the measured signalThe Voltage is the same, after multi-gear selection of program-controlled amplification, sampling and holding, A/D conversion, in the microcomputercalculates the True RMS Voltage (IRMS) and outputs the value to the display.
