The Triplett 1101-B Compact Digital Multimeter is a digital multimeter (also known as a multitester) with 19 measurement ranges and functions including AC/DC voltage to 600V, DC current to 10 amp, resistance to 2 megaohms, and a continuity beeper and diode test. The included K-type thermocouple measures temperature to 300 degrees F, and with high temperature probe (not included) the meter can measure temperature ranges from -4 to +1,832 degrees F. The continuity beeper has a range of 0 to 2000 ohms and the beeper sounds if resistance is lower than 50 ohms. The LCD with 3-1/2 digit (1,999 count) resolution is backlit for readability in low-light conditions. Overload protection makes the meter resistant to damage from accidental overloads. A data hold function will freeze the present LCD reading. The operating temperature range is 32 to 105 degrees F in a relative humidity of less than 85% and storage temperature range is 14 to 125 degrees F in a relative humidity of less than 85%. The meter has a protective rubberized boot that resists impact and a built-in stand. It uses a 9V battery (included) with a battery life of approximately 200 hours and features an auto power-off function to help preserve battery life and a low battery indicator on the LCD. It is safety rated for Categories I and II to 600V AC/DC. The meter measures 5.75 x 2.7 x 1.2 inches (H x W x D) and weighs approximately 6 oz. including battery. (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 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.

Triplett manufactures test equipment for electricians, home security installers, and telecommunications technicians. The company, founded in 1904, is headquartered in Manchester, NH.
