The HT3013 clamp meter measures AC/DC current up to 400 A and AC/DC voltage up to 600 V, as well as resistance, frequency, capacitance, continuity, temperature via K-type probes, and diode testing. It provides visual (LED) and audible (buzzer) indication of AC voltage presence via a contactless internal detector. Compliant with IEC/EN61010-1 standards, suitable for both residential and industrial measurements.
