The K2009A is designed for superior performance, value and has been redesigned to meet the IEC 61010 Safety Regulations. The new custom designed LCD has a maximum of 4000 counts, and has microprocessor controlled annunciators and the decimal point. The K2009A has added features that include an Auto Zero adjustment button for the DC current range as well as an OUTPUT terminal for current measurements that provides a DC voltage in proportion to the reading on AC or DC current range, ideal for long term monitoring with a recorder or other recording devices. A unique terminal cover encloses the input terminals for COM and V/Ω, when the OUTPUT terminal is being used, thus avoiding accidental application of voltage to the instrument. The tear-drop-shaped jaws with a maximum conductor diameter of 55mm allow easy access with conductors and the rugged construction withstands heavy-duty job site abuse. The K2009A True RMS clamp meter offers a unique feature with the LoHz mode which automatically selects a lower sample rate in low frequency measurement to reduce the fluctuations of display readings. The average mode allows easy reading of fluctuating voltages and currents.
