Typical meter used in Canadian industry.

Function

A low cost meter used generally in experimental or homemade amateur radio equipment to measure transmitter grid current etc. Measures DC current of batteries in milliamperes.

Technical

DC switchboard milliammeter of the moving iron type (see ref. 3). Cheap construction. The instrument was designed to be small and sturdy. The calibration screw is inside the instrument, meaning that the operator would seldom use it. This indicates that the meter was not meant to be highly accurate.
