Ultra-high pulse current probeThe current loop adopts standard BNC interface, which seamlessly adapts to mainstream oscilloscope brands such as Tektronix, Rhodes, Sis, Puyuan, etc. Plug and play is not required. Support DC-2MHz wide-band current measurement, from milliampere standby power consumption to 100,000 ampere surge current can be accurately captured. The industrial-grade shielding design effectively suppresses electromagnetic interference, and can still output pure waveforms even in strong noise scenarios such as frequency converters and motor drives. |
Numerical measurement functionThrough the complimentary BNC to banana plug, the mV voltage signal output by the current probe is connected to the multimeter to directly read the AC current value. This scheme is suitable for mainstream brand multimeters such as Tektronix and Fluke. It uses its mV gear to analyze the voltage of 0.1mV ~ 1000mV with high precision (1%) and automatically converts it into 1mA-100A current (according to probe sensitivity). |

Surge Waveform CaptureDesigned for μs surge current observation, the 200ns transient response capability of the current loop accurately captures the wave head time (1.2μs ± 30%) and half peak characteristics of 100kA lightning strike waveform. BNC interface directly connected to the oscilloscope, combined with poor grounding sound and light alarm function to ensure test safety. Hard probe with 50mm diameter, suitable for photovoltaic lightning protection system failure point positioning. |
Start-up current testAt the moment when the motor starts, the rotor is in a static state, and the stator winding generates a rotating magnetic field after the power is turned on. At this time, the magnetic field cuts the rotor winding at the maximum relative speed (synchronous speed), and a very high potential is induced in the rotor conductor, thereby generating a large current. The magnetic flux generated by this current will cancel the stator magnetic field, and the stator is forced to input a larger current to maintain the magnetic flux matching the power supply voltage, forming an initial current peak. |
