3.Application

4. Characteristics

☆ Analog resistance output

1. Higher measurement accuracy with the four-wire wiring method.
2. Self-calibration.

 

☆ Wide range of current measurement

1. Direct current measurement: A pair of quick terminals can be used to directly measure the AC and DC current in a wide range of 10 m A  ~ 60 A.
2. Current conversion measurement: The instrument is equipped with a sensor-specific measurement interface, which can simultaneously supply power to the sensor and measure its secondary signal, and can be connected to a precision current sensor (such as TH0550T) and extend the current range to 100 A, 200 A, 500A and beyond. By setting the ratio of the current sensor on the instrument, the magnitude of the primary current of the measured sensor is directly displayed.

 

☆ AC/DC comprehensive measurement

1. The instrument supports DC or AC (optional) measurement mode, AC frequency range: 45 Hz ~ 65 Hz.
2. When measuring the current, the distortion degree and ripple can be measured synchronously. The maximum measurement bandwidth of DC ripple is 1 kHz, and the AC supports the measurement of the 2^nd~32^nd harmonics

 

DC characterization
S/N	Function
1	Current overshoot: the maximum test current is displayed in DC mode, which is convenient for calculating the working current overshoot;
2	Waveform display: With oscilloscope function, the waveform of the measured current can be displayed in real time.
3	Ripple measurement: the instrument directly displays the ripple measurement results on the screen, which is convenient for users to read.

 

AC characterization
S/N	Function
1	Harmonic distortion: The instrument directly calculates two types of harmonic distortion, THD/T (harmonics relative to full wave) and THD/F (harmonics relative to fundamental waves).
2	Harmonic data: display the amplitude (RMS), content (%) and phase of the 2^nd~32^nd harmonics.
3	DC component: display the DC component in the AC current signal.
4	Waveform display: With waveform display function, the waveform of the measured current can be displayed in real time.

 

Statistical analysis of test data
S/N	Function
1	Integration period: The integration period can be set in the range of 0.5 s  ~ 20 s (default  1s), which is convenient for users to set sampling data according to actual needs;
2	Statistical analysis: Real-time recording and statistical test data, including current Max, Min, Avg, Span, Stab, S. dev, Time, test times N, etc.
