3.Application
4. Characteristics
☆ Analog resistance output |
• Higher measurement accuracy with the four-wire wiring method. • Self-calibration. |
☆ Wide range of current measurement |
• 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. • 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. |
☆ Multiple output methods |
• The instrument has a "fixed point output" mode, through the digital button of the control panel or click the touch screen, directly set the required output value, the instrument will automatically switch to the best range output. |
☆ Multiple output methods |
• When calibrating a resistance tester, it is usually necessary to select the calibration point according to the proportion of each range of the meter to be checked. • The user can easily select the calibration point of the inspected meter through the "Percentage Output Button" on the console of this instrument or the "Percentage Check Point" on the touch screen. |
• The operating area is equipped with a "rotary encoder" that increases or decreases the output by rotating it clockwise or counterclockwise. |
☆ AC/DC comprehensive measurement |
• The instrument supports DC or AC (optional) measurement mode, AC frequency range: 45 Hz ~ 65 Hz. • 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 2nd~32nd harmonics |
☆ DC characterization | |

Waveform display: With oscilloscope function, the waveform of the measured current can be displayed in real time. | |
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 |
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). | |
Harmonic data: display the amplitude (RMS), content (%) and phase of the 2nd~32nd harmonics. | |
