ApplicationsNote: When using TH30000 to calibrate electrical measuring devices or resistors, it is necessary to use the orresponding test power supply. Calibrating energy metering device: the instrument can be used as a high-grade electric energy standard meter, used to assess AC energy meter verification device, DC energy meter verification device, standard energy meter, electric vehicle charger tester and other equipment, its DC+AC measurement mode is also especially suitable for the verification and calibration of DC energy meter verification device with ripple detection function. Calibrate the electrical measurement standard sources: direct verification or calibrate AC and DC voltage sources, current sources, power sources, etc. Calibrating electrical measuring instruments: it can be used as a standard meter, with the test power supply to verify or calibrate voltmeters, ammeters, resistance meters, power meters, power factor meters, frequency meters, phase meters, transmitters, sensors, etc. 4. Characteristics☆ Wide range of current measurementDirect current measurement: use a pair of quick connect terminals to directly measure 10 μ A ~ 120 A (DC);10 μA ~ 80 A (AC) wide range DC current.Current conversion measurement: The instrument is equipped with a sensor-specific measurement interface, which can supply power to the sensor and measure its secondary signal at the same time, and can be connected to a precision current sensor (such as TH0540) to extend the current range to 500 A, 1 kA or even more, and directly display the size of the primary current of the measured sensor by setting the ratio of the current sensor on the instrument. ☆ AC/DC comprehensive measurementThe instrument supports DC, AC and DC+AC measurement modes, AC fundamental frequency: 40 Hz ~ 1 kHz.When measuring voltage or current, distortion and ripple measurements can be completed simultaneously, and the maximum measurement bandwidth of DC ripple is 5 kHz, and AC supports the measurement of the 2nd ~ 63rd harmonic. The DC+AC measurement function is very suitable for detecting energy meter verification devices with ripple or harmonic output. ☆ Precision small signal voltage measurementSupport 0.1 m V ~ 12 V (DC); 2 m V ~ 10.2 V (AC) small signal voltage measurement, equipped with ultra-low thermal electric potential terminals and test wires, and can improve measurement accuracy and withstand overload signals up to 150 Vpk at most.Application scenario 1: With a stable high-current source and precision current sensor, it can be used to calibrate shunts or other I/V converters. Application scenario 2: With its own precision voltage measurement function, it can be used to evaluate the indirect access DC energy meter verification device. ☆ Power calculation function The instrument has the function of power calculation, the user can connect the voltage divider, shunt, transformer, sensor and other range extenders, and set the scale k and offset b, measure the secondary output signal x of the extender through the instrument, and then calculate the actual value of the primary electricity to be measured according to the function f(x) = kx + b. ☆ DC ripple / AC harmonic measurementS/NFunction 1With DC ripple test function, it can measure the ripple content in the range of 1 Hz ~ 5 kHz. The ripple waveform can be displayed in real time, and the rms value (RMS) and peak-to-peak value (P-P) of the ripple can be measured.2AC power measurement also has an oscilloscope function, which can display the waveform of the AC signal under test in real time.3Calculate two types of harmonic distortion: THD/T (harmonic relative to full wave) and THD/F (harmonic relative to fundamental wave). 4The amplitude (RMS), content (%) and phase of the 2nd ~ 63rd harmonic of each phase voltage or current can be analyzed in real time. 5Visualize the spectrum of each harmonic (100% fundamental) in the form of a histogram. ☆ Data statistical analysis functionS/NFunction 1Data statistical analysis: calculate the maximum (Max), minimum value (min), peak-peak (P-P), average value (AVG), standard deviation (S.dev), divergence (Div), etc. of the measured electricity. 2Power Trend Test: Curve the power over time in real time during the test cycle. 3Normal distribution histogram: Displays the distribution of the amount of electricity being counted during the test period. 5.
