Using zero flux technology (Hall element) current sensor, dual range design covers small to large current, accurate observation of current waveform. Whether the current fluctuation of the high-efficiency switching device, the current of the power-saving device as low as 1mA, or the high-speed transient current of the power-on, it can be handled. Excellent frequency response ability, can analyze and display the current waveform containing multiple frequency components, such as switching frequency, pulse waveform, etc., so as to meet the comprehensive measurement needs of complex current signals.

Economical Small Current ProbeBNC interface directly connected to Keysight, Tektronix, RIGOL and other mainstream oscilloscope, exempt from driver installation. Domestic Guwei/Dingyang to imported Tektronix plug and play, 30 seconds to complete the current test link construction. Standardized interface design eliminates the trouble of switching and seamless switching from laboratory to production line. |
Intelligent jawWith a compact jaw diameter of only 5mm, this professional current probe is designed for wiring measurements in narrow spaces and can easily grip small wires. Its intelligent sensing function ensures safe and reliable measurement-when the jaws are not completely pushed to the bottom and locked, the probe will clearly light up the red light prompt, effectively preventing data errors or poor contact caused by negligent operation. |

Auto zeroThis current probe is equipped with an intelligent one-key zero adjustment function. It can automatically complete degaussing and zero adjustment by pressing the ZERO button, eliminating the need for cumbersome manual calibration and greatly improving measurement efficiency. Built-in auto-zero technology ensures high-precision data acquisition and eliminates environmental interference errors, especially for precision electronic testing, industrial automation and laboratory scenarios. Easy and fast operation reduces human error, allowing engineers and researchers to focus on core testing tasks. Whether it is high-frequency current measurement or weak signal analysis, it can provide a stable and reliable zero reference. |
Dual range design30MHz bandwidth dual range coverage, RANGE one-button switching 0.1V/A high range (30A) and 1V/A low range (5A),5mA high resolution accurate capture of small current fluctuations, suitable for power conversion and motor drive testing, 1% accuracy to ensure industrial reliability. |
