The A6303 current probes offer current measurement capability for the lab and bench environment. The A6303 measures higher amplitude, lower frequency currents. It clips onto conductors up to 21.1 mm (0.83 in.) in diameter. Its frequency range is DC to 15 MHz. It will measure continuous currents up to 100 A and peak currents up to 500 A, as long as the Amp*second product of 10,000 A*us is not exceeded.
