The Triplett 60 Ruggedized Volt-Ohm Milliammeter is a manual-ranging meter and has 28 ranges for measuring AC/DC voltage to 1,000V, DC current to 1,000mA, resistance to 10 megaohms, and decibel ranges from -20dB to +62dB. It employs three-fuse overload protection to prevent damage and keep the user safe with 1/8 and 1 Amp fuses for normal overload conditions (spares for each included) and a 2-amp fuse for high energy fault currents. The meter has a polarity-reversing switch, a mirrored scale to reduce parallax error, and confidence check to test batteries, fuses, leads, and meter accuracy. The meter comes in an orange case that helps protect it from 5' drops and rough handling. The meter measures 3-1/4 x 5 ¼ x 7 ¼ inches (H x W x D) and weighs 2 ½ lb. (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.
