Functional Features

◉ Wide measurement range: With only one pair of terminals for each phase current, a wide range of AC current measurement and automatic range switching can be achieved.
The transformer will not be damaged or the measurement accuracy will not change even if a large current is suddenly applied in any range without shifting once.
Minimum current measurement: The TD3810R has a minimum measurement limit of 0.2 mA, which can assess the power/energy accuracy and stability of the device and standard meter at the minimum starting current.
Harmonic measurement function: Real time analysis and display of the content of the 2nd to 127th harmonics, total harmonic distortion, and use to draw a harmonic histogram (frequency spectrum).
◉ Waveform display function: The measurement channel has a waveform display function, which can display the waveform and phasor diagram of the measured AC power in real time.
◉ High reliability of the instrument: Switching on and off under extreme conditions (500 V, 100 A) not only does not damage the instrument, but also ensures accurate measurement values.
Statistical analysis function: It can calculate the maximum, minimum, average, and standard deviation of voltage and current, and analyze power stability and variation trends.
◉ Device magnetic field measurement: Equipped with a three-axis magnetic field sensing probe, it can measure the magnetic flux density or on-site environmental magnetic field at the location of the device being tested.
◉ Gauge difference measurement: It can measure the gauge difference of the AC energy meter calibration device and can continuously withstand a voltage of 380 V.
◉ Temperature and humidity measurement: External temperature and humidity sensors can be used to measure and record the temperature and humidity of the on-site detection environment.
Clock tester: Equipped with PPS standard second pulse input/output function, it can assess the clock error of the device.
◉ Human machine operation function: Equipped with an ultra large LCD touch color screen, the measurement value display is more intuitive and the operation is more convenient.
◉ Rich communication ports: equipped with RS232, USB, RJ45 and other ports, making it easy for software to obtain real-time measurement data, providing convenience for further research applications and big data analysis.
◉ Convenience for on-site use: Equipped with a dedicated pull rod instrument box, the host, test wires, laptop, etc. can be placed inside, making transportation very convenient.
The notebook is equipped with specialized software that meets the requirements of JJG 597, which can automatically complete error analysis of the device on site, record data, and export/print certificates.
