Megger Avo300 Cable Tester

The Megger AVO300 digital multimeter is an average-sensing, auto-ranging meter for measuring current, voltage, and resistance in electrical testing applications. The meter comes with a set of detachable test leads that measure alternating current (AC) and direct current (DC) to 10 amp, AC voltage and DC voltage to 1,000 volts (V), and resistance to 40 megaohms. The hold function keeps a reading on the display, even after the meter is disconnected. An audible continuity sensor confirms that the circuit conducts electricity, and a diode test detects proper functioning of a circuits diodes. The unit automatically turns off after 15 minutes of non-use to conserve battery life, and a low-battery indicator signals when the meter’s batteries need to be replaced. A built-in stand on the back of the meter props up the meter on a flat surface or serves as a hanging bracket for suspending the meter from a hook. The meter has a molded rubber case that helps protect against damage from falls, impacts, and abrasion. It can survive falls of up to 1.2 meters to a hardwood or concrete floor.This average sensing, or average responding, meter provides accurate readings when measuring linear loads, such as standard induction motors and incandescent lights, where the current or voltage has a sinusoidal waveform. It is an auto-ranging multimeter and automatically selects the correct operating range for the property being measured. The meter has a 4,000-count resolution, meaning it can display up to 3,999 units (3-3/4 digits) before the operating range needs to be changed. It meets International Electrotechnical Commission (IEC) safety standard 61010 and is certified for category II installations up to 1,000V, which covers large household appliances and devices connected to a fixed power supply (such as refrigerators and air conditioners), and category III installations up to 600V, which covers items used with enclosed building circuit installations (such as service panel parts, branch circuits, and fixed installations that are connected directly to a building’s AC power supply)
