The Extech EX613 is a 400 Amp dual input AC/DC Clamp meter with built in non-contact voltage detector. This TRMS AC/DC Clamp Meter has dual thermocouple inputs for T1, T2, T1-T2 Differential Temperature measurements. This DMM measures AC/DC Voltage and Current, Resistance, Capacitance, and Frequency. Additional features include: DC micro-amp function for flame rod measurements, Diode open circuit voltage of 2.8 Volt, Data Hold plus fast Peak Hold for capturing current surges at motor startup, and capacitance measurement to 40mF. The EX613 displays 40,000 counts on its LCD screen and is built in a rugged double molded housing.
