Simpson 463 Benchtop Digital Multimeter DMM 1000V 750V AC DC 20MΩ

Simpson 463 Benchtop Digital Multimeter DMM 1000V 750V AC DC 20MΩ

The Simpson Model 463 is a benchtop digital multimeter designed for laboratory, service bench, and general electrical measurement work. It measures DC and AC voltage, DC and AC current in the milliamp range, and resistance, with results shown on a large 7-segment LCD display. Five push-button function selectors select the measurement mode (kΩ, V DC, V AC, mA DC, mA AC), and a separate row of range buttons covers 200mV through 20MΩ. Maximum input ratings are 1000V DC and 750V AC. The unit is powered by a standard 9V battery (NEDA 1604 / 6F22); a 9V Duracell alkaline battery is currently installed.

Applications

The Simpson 463 is a classic American-made benchtop DMM from the 1970s–1980s era, a period when Simpson Electric of Elgin, Illinois was one of the most recognized names in analog and digital test instruments. Benchtop DMMs like the 463 were standard equipment on electronics service benches, in school and university labs, and in industrial maintenance shops — anywhere a stable, easy-to-read tabletop meter was preferred over a handheld unit. The large LCD display and push-button range selection made it well suited for extended bench sessions where repeated readings are taken. The Simpson 463 is still sought by technicians who prefer the straightforward layout of these older bench meters, as well as by collectors of vintage American test equipment. It is suitable for general AC/DC voltage, resistance, and milliamp current measurements in electronics service, hobbyist, and educational lab settings.
