Autoranging clamp meter covering AC current to 400A alongside AC/DC voltage, resistance, frequency, capacitance, duty cycle and a wide -20 to 760C temperature range, housed in a double-molded plastic shell with a 30 mm jaw opening. It includes diode-check, continuity, and a non-contact voltage detector in the clamp tip, and this NIST-certified version ships with a calibration certificate.
