The B&K Precision 2704C digital multimeter (also known as a multitester) is an average-sensing, manual-ranging meter that measures current, voltage, resistance, and capacitance, and performs diode, continuity, logic, and transistor common-emitter gain (hFE) tests in electrical applications. An audible continuity sensor confirms a circuit conducts electricity, and a diode test detects proper functioning of a circuit's diodes. The hFE test measures a transistor's common-emitter gain, and a logic test analyzes digital signals. A data hold function keeps a reading on the display for recording, even after the meter has been disconnected. The LCD is backlit for readability in low light. It displays the present measurement or the highest or lowest reading in a session, for tracking sudden changes in readings. An alarm sounds when the test leads are connected to the wrong jack for the measurement being taken. A low-battery indicator signals when the meter's batteries need to be replaced. A magnetic strap is included for hanging the meter from a metal door or surface for hands-free use. The meter comes with a set of detachable test leads.
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 a manual-ranging meter that requires the operator to choose the appropriate operating range for the property being measured. The LCD has a 2,000-count resolution, meaning it can display up to 1,999 units (3-1/2 digits) before the operating range needs to be changed. It meets European Union EMC (EN) EN61326, International Electrotechnical Commission (IEC) safety standard 61010, and is certified for Category II installations up to 1000V, which covers large household appliances and devices connected to a fixed power supply (such as refrigerators and air conditioners), 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), and Pollution Degree 2 for indoor use. The meter includes a set of detachable test leads, a spare fuse, a magnetic strap, a 9V battery, and instructions.SpecificationsMaximum alternating current (AC) input10 ampMaximum direct current (DC) input10 ampMaximum AC voltage input750VMaximum DC voltage input1000VMaximum resistance detected2,000 megaohmsMaximum capacitance detected20 microfaradsFrequency counterTo 20MhzTestsDiode, continuity, logic, and hFE transistor testPower supply9V battery (one, installed)Safety ratingsEuropean Conformity (CE); International Electrotechnical Commission (IEC) safety standard 61010-1; European Union EMC (EN) EN61326WeightApproximately 10oz./285g (including battery and hanger)Dimensions165 x 78 x 42.5mm/6.5 x 3.1 x 1.7 inches (H x W x D)

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 voltage. Safety ratings are based on International Electrotechnical Commission (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.
