Fluke 113 True-RMS Utility Multimeter

The Fluke 113 True-RMS Utility Multimeter is a digital multimeter (also known as a multitester) that offers a range of measurement capabilities. This true RMS meter provides accurate readings when measuring linear or nonlinear loads where the current or voltage has a sinusoidal or non-sinusoidal waveform, and it can simultaneously check for voltage and continuity. It has both manual- and auto-ranging capabilities, allowing for user flexibility.

The meter measures AC/DC voltage up to 600V, resistance up to 60 kiloohms, and capacitance up to 9,999 microfarads. It also features a diode check function for testing general-purpose germanium, silicon, and power diodes, as well as a continuity beeper that provides audible detection of resistance by turning on at less than 25 ohms and off at 250 ohms.

With a 6000-count resolution and a 3-1/2 digit digital display that is backlit for readability in low-light conditions, the Fluke 113 offers a Max/Min function to record signal fluctuations and a hold function to freeze measurements on the display. It is safety rated for Category III to 600V and Category IV to 300V, in accordance with International Electrotechnical Commission (IEC) standards for low-voltage test equipment.

Powered by a 9V battery (installed) with a battery life of approximately 300 hours without backlight, the meter has a sleep mode to maximize battery life. Measuring 6.58 x 3.35 x 1.81 inches (H x W x D) and weighing 13 oz. /404 g, the Fluke 113 includes a holster with built-in probe holders for convenient storage.

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, they are used to 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, and the information is displayed in either 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 IEC standards, with a higher category rating providing more protection against transient voltages.
