The 157 is a professional AC/DC leakage current tester designed for both the electrical and automotive industry. This meter has a frequency filtering function for measuring currents of fundamental frequency. This filter function is useful when checking whether the leakage breaker was tripped by leakage currents or by effects of harmonics.
