Period

1930-1940

Canada

Typical meter used in Canadian industry.

Function

Used to measure, in amperes, the charge or discharge current in a battery power system.

Technical

Polarized vane panel DC ammeter for battery testing. Significant improvement over previous meters in terms of ruggedness. This meter was designed to be operated while being subjected to mechanical vibrations for long periods of time without being damaged. Other meters would quickly wear their bearings. The meter is also well shielded from external magnetic fields. The polarized vane technology, though not very accurate, is extremely durable. The scale is made out of metal instead of paper to avoid damage due to humidity. This model was extremely popular "for use with automobile starting and lighting systems and battery chargers" (see ref. 5 - Weston Catalog 10)
