Product Description ------------------- The Amprobe AM-220 digital multimeter is an average-sensing, auto- or manual-ranging meter for measuring current, voltage, resistance, capacitance, frequency, microcurrent, and duty cycles 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 600 volts (V), resistance to 40 megaohms, capacitance to 4,000 microfarads, frequency to 10 megahertz (MHz), AC and DC microcurrent to 4,000 amp, and duty cycles to 99%. The microamp reading identifies current changes in flame detector applications. The 4,000 microfarad capacitance rating is for testing run/start capacitors on motors. 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 for quick comparison of readings. The hold function keeps a reading on the display, even after the meter is disconnected. The backlit liquid crystal display (LCD) is visible in low light. An audible continuity sensor confirms that the circuit conducts electricity, and a diode test detects whether the circuit's diodes work properly. An auto power-off mode turns off the unit 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 back of the meter has a tilt stand that allows the meter to be propped on a surface for hands-free use. 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. Two ranging modes (auto or manual) offer a range of operator control when taking readings. 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 4,000-count (3-3/4 digit) liquid crystal display (LCD) that can display up to 3,999 units before the operating range needs to be changed. It meets International Electrotechnical Commission (IEC) safety standard 61010 and is certified for 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).

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. Amprobe manufactures electrical testing equipment for commercial, industrial, and home use. The company was founded in 1948 and is headquartered in Everett, WA.

In 1960 the company name was formally changed to Amprobe Instrument Corporation. Amprobe continued to design, engineer, manufacture and distribute product from its Lynbrook, NY location until it was merged to form ATP and relocated to South Florida in late 1999.
