Function

Measures DC voltage in volts. Used for testing batteries.

Technical

Permanent magnet movable coil type DC fan-shaped portable miniature voltmeter. Used for testing individual cells of storage batteries. This is a more accurate instrument than the smaller round battery testing meters that were common at the time because it has and has the same moving coil movement as the Model 280 portable precision instruments. It also has a longer scale and is more expensive. Fan-shaped instruments are designed to have very long scales while keeping the case compact. Weston claims that its fan-shaped meters have the longest scales in the world relative to their size.
