MILLER ME-522 Digital Multimeter (Nonfunctional)

Circa 1978 (ESTIMATED)

A digital multimeter (DMM) designed for general-purpose electrical testing and troubleshooting.

Use Cases:

Designed to measure fundamental electrical properties—voltage, current, and resistance—to diagnose faults in a variety of systems.

• Electronics Benchwork: Testing components like resistors and diodes on circuit boards.

• Home & Industrial Maintenance: Checking wall outlets, switches, and machinery for proper voltage and continuity.

• Automotive Diagnostics: Identifying issues with batteries, fuses, and sensors in vehicle electrical systems.

• HVAC & Appliances: Troubleshooting thermostats, heating elements, and control circuits in household or commercial equipment.

Historical Significance:



The ME-522 is a notable example of the digital revolution in field service tools. It represents the shift from delicate, needle-based analog meters (like the Triplett 666-R) to more durable, accurate, and easy-to-read digital displays. This era of meters brought high-impedance inputs to the field, allowing technicians to measure sensitive electronic circuits without "loading" or distorting the signal.

Included Accessories:

• Test Lead Set.
