The Extech 380926 is a 2,000 A Category IV TRMS AC/DC clamp meter with a robust 50 mm wide clamp jaw for two 500 MCM cables. An integrated full-function DMM can measure DC/AC voltage and current, resistance, capacitance, frequency, duty cycle, diode and continuity. The measured values are clearly visible on the large, backlit display with counts up to 4,000, even in dimly lit areas. Other features include the DCA push button, which can be used to set the display to zero, data storage and the "Relative" function. Includes test leads and 9 V battery.
