Période

Period Used until approximately 1968, as before then the calibrations had been semi-annual.

Canada

Typical voltmeter used in Canadian industry.

Fonction

Measures voltage in volts.

Technique

Moving iron AC flush type switchboard voltmeter. The square shape made it economical to place many of these meters side by side or on top of each other. The round shape which one often finds in switchboard meters is only used for aesthetic reasons or because the round shape is easy to manufacture. This square shape was probably only possible thanks to advances in working with sheet steel. The wide screen allows in a lot of light and makes the scale very visible from a distance. This model is designed for affordability and so the case is simpler and less elegant than other voltmeters by the same manufacturer. It is quite possible that voltmeters of this type were of standard use at schools and universities.
