The amp clamp is designed to measure which frequency range?

Explanation:
An amp clamp measures current by sensing the changing magnetic field around a conductor. That sensing works best when the current is alternating, because the clamp’s transformer or Hall sensor responds to the changing flux. Power systems around the world run at either 50 Hz or 60 Hz, so the clamps are designed to reliably measure those mains frequencies. DC (0 Hz) wouldn’t produce a varying magnetic field, so a traditional clamp wouldn’t read it well. Including both 50 Hz and 60 Hz covers the regions where different frequencies are used, which is why 50/60 Hz is the best choice.
