Overview

Model TD4507, a portable calibrator for AC sampling and transmitters. Composed of electrical parameters measurement, AC sampling calibration, harmonic analysis, waveform and phasor diagram display, data management or other functions. Applied to calibrate the AC sampling devices by real load in field for electric power.

Functions

● Electrical Parameters Measurement: The AC voltage is from 10 V to 480 V, the current is from 0.05 A to 12 A. Automatic or manual switching on all ranges.

● Current Measurement by Clamp: Online measurement of current on AC lines from 0.1 A to 120 A.

● Waveform Display: Oscilloscope function can display the waveform of the measured electrical parameters in real time.

● Phase Measurement: Measure phase difference between the three-phase electrical parameters, and intuitively display by phasor diagram.

● Harmonic Analysis: Measure 2nd to 31st harmonic, analyze harmonic content and total harmonic distortion, and draw harmonic histogram.

● Wiring Identification: Identify various three-phase wiring modes, report the results and provide the correction coefficient of parameters.

● Transmitter Measurement: It can display the measured electrical parameters in real time or display the physical quantities such as temperature and pressure.

Features

● Power Supply: AC power supply mode, or high-capacity lithium battery power supply mode with a continuous operation time of more than 8 hours.

● Data Storage: Record the measurement data of thousands of measured meters, and transfer it to the management software.

● Human-Computer Interaction: The function of locking screen is convenient for operators to read and switch the lock/unlock with one-touch.

 Display: Large LCD touch screen, more intuitive of value display and easier operation.

● Portability: The portable box with small size and light weight is easy to carry.
