Comprehensive test and measurement service provider-Shenzhen Weike Electronic Technology Co.
Wide bandwidth from DC to 2MHz allows measurement of large currents up to 500A. Suitable for current measurement of switching power supplies and other power supply peripherals.
● Direct input to the oscilloscope's BNC terminal
● Waveforms can be observed in the memory recorder.
● Using the optional dedicated power supply, it is possible to provide a power supply other than that of the oscilloscope.
※Please use it on the main unit of a measuring instrument with a high input impedance of 1 MΩ or more.
