Basic high-precision current probe

50A high-current scenario still maintains BNC full interface compatibility, Yokogawa DLM3000/McCorson TO series direct connection available. No-drive design to avoid the risk of system conflict, strong electromagnetic environment plug-and-measure.

Intelligent jaw

5mm slim jaw, easily into the small space, accurate measurement of the current signal in the compact circuit. Its intelligent design ensures safe and reliable operation: when the jaws are not fully pushed into the locked position, the probe will immediately light up the eye-catching red light prompt, effectively preventing measurement errors or safety hazards caused by negligent operation.

Auto zero

Press the ZERO button to trigger the probe built-in automatic zero function, instantly complete the zero adjustment of degaussing, completely eliminate the residual current interference. This innovative technology simplifies the operation process, eliminates manual calibration steps, and ensures accurate measurement at the milliampere level. Engineers can still quickly obtain reliable data in complex electromagnetic environments, greatly improving test efficiency and equipment stability.

Dual range design

The 30MHz bandwidth supports 50A high current test, the innovative dual-range RANGE key switches 0.1V/A(50A) and 1V/A(7.5A) with one key, and 1mA ultra-high resolution to capture weak signals. It is specially designed for new energy electric drive and industrial control.
