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.

Basic high-frequency high-precision current probeThe anti-interference BNC interface is compatible with the mixed environment of domestic Dingyang SDS5000X and imported Tektronix MDO4000. Insert the oscilloscope channel to automatically match the range, change the test platform does not need to reconfigure. |
Intelligent jawEquipped with 5mm jaw, specially set intelligent locking warning. When the jaws are not fully pushed to the closed position, the probe will automatically trigger a red light prompt to intuitively remind the user to operate correctly. The design effectively prevents measurement deviations or safety hazards caused by operational omissions, and is especially suitable for non-contact current measurement in space-constrained power distribution cabinets, precision circuit boards and industrial equipment. 5mm small diameter easily cope with narrow wiring environment. |
