Megger DCM340-ENTCAL AC/DC Clamp Meter, 400 Ohms Resistance, 600V AC/DC Voltage, 600 Amp AC/DC Current, 400Hz Frequency with a NIST-Traceable Calibration Certificate with Data

The Megger DCM340-EN digital clamp meter is an average-sensing Multi meter for measuring current, voltage, resistance, and frequency in electrical testing applications. It has a clamp with two jaws that can close around an electrical conductor up to 1.3" (35 mm) in diameter to measure current without touching or interrupting the circuit. The meter comes with detachable test leads that measure voltage, resistance, and frequency. The peak + or - function records instantaneous peak positive or negative values for current and voltage. The maximum or minimum reading mode displays the highest or lowest reading in a session to track a sudden increase or decrease in readings. The relative zero mode stores a reading in memory to use as a zero point for subsequent readings, allowing quick comparison of multiple readings. An audible continuity sensor confirms that the circuit conducts electricity. 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 30 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. The meter can survive falls of up to 1.2 meters to a hardwood or concrete floor.
