Megger DCM300ETCAL Ground Leakage Clamp Meter, 300 mA, 300 Amp Current with a NIST-Traceable Calibration Certificate with Data

The Megger DCM300E digital ground leakage clamp meter is an average-sensing meter for measuring alternating current (AC) and for locating ground faults in electrical testing applications. It has a clamp with two jaws that can close around an electrical conductor up to 1.57" (40 mm) in diameter to measure current without touching or interrupting the circuit. The meter's 10-microamp minimum resolution detects small amounts of leaking current in ground faults. The hold function keeps a reading on the display, even after the meter is disconnected. The meter's liquid crystal display (LCD) shows readings in digits and on a bar graph and is backlit to provide readability in low light. The unit automatically turns off after 10 minutes of non-use to conserve battery life, and a low-battery indicator signals when the meter's batteries need to be replaced. A finger guard on the body of the meter helps protect fingers from shock, and insulation around the jaw helps reduce the risk of short circuiting live conductors.
