Megger AVO410-US Digital Multimeter, 1000V DC, 750V AC Voltage, CATIV 600V Rated

The Megger AVO410-US digital multimeter is a true RMS (root mean square) sensing, auto- or manual-ranging meter for measuring current, voltage, resistance, capacitance, and frequency in electrical testing applications. The meter comes with a set of detachable test leads and probes that measure alternating current (AC) and direct current (DC) to 10 amp, AC voltage to 750 volts (V), DC voltage to 1,000V, resistance to 60 megaohms, capacitance to 6 millifarads, and frequency to 60 megahertz (MHz). The microamp reading identifies current changes in flame detector applications. 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 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 circuit’s diodes. The meter's backlit liquid crystal display (LCD) is readable in low light. The meter has an RS-232 port for connecting the meter to a computer (USB adapter and cable not included). 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. The meter comes with a molded rubber holster that fits onto the meter to help protect against damage from falls, impacts, and abrasion. The meter can survive falls of up to 1.2 meters to a hardwood or concrete floor.

This true RMS (root mean square) sensing 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, or non-linear loads, such as electronic devices or motors, where the current or voltage has a non-sinusoidal waveform. When turned on, the meter is in auto-ranging mode and automatically selects the correct operating range for the property being measured. It can be switched to manual-ranging mode, which allows the operator to choose the appropriate operating range. The meter has a 6,000-count resolution, meaning it can display up to 5,999 units (3-5/6 digits) before the operating range needs to be changed. It meets International Electrotechnical Commission (IEC) safety standard 61010 and is certified for category IV installations up to 600V, which covers measurements at the source of the low-voltage supply, such as electricity meters and overcurrent protection devices.

H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Multimeters are electrical test meters that measure multiple properties of an electrical circuit, such as current, voltage, resistance, capacitance, and continuity. Available in handheld or benchtop models, multimeters diagnose electrical problems in electrical equipment, wiring, and power supplies. A variety of probes, clamps, and leads can be used to connect the meter to a circuit or device. Multimeters display information either in analog or digital form. Factors that influence meter choice include the electrical properties to be measured, the anticipated range of results, and the desired level of protection against transient voltages. Safety ratings are based on the International Electrotechnical Commission's (IEC) standards for low-voltage test equipment. IEC 61010 delineates four overvoltage installation categories. In general, a meter with a category IV rating will provide more protection against transient voltages than a meter with a lower category rating.
