The HHM-MA640 is a true RMS clamp meter. This meter measures AC current, DC current, AC/DC voltage, resistance, capacitance, frequency, diode test, duty cycle and continuity. The molded case is designed for heavy duty use. The integrated non-contact voltage detector quickly checks for the presence of live wires before testing needs to be started.
