The tcpa300 and tcpa400 acdc current clamp systems are the ideal solution for all current measuring tasks split core technology combined with a hall sensor allows dc measurements to be made up to 100 mhz at signal levels from under 1ma up to several thousand ampere all oscilloscopes with 50 input can be connected directly to the tcpa series if these current measurement systems are connected to oscilloscopes with tekprobe level ii or tekconnect interfaces all parameters are automatically t
