Made by the Canadian subsidiary of General Electric, this voltmeter owes its' unique shape to its expected placement next to a switchboard.

Function

Measures AC voltage in volts.

Technical

Permanent magnet moving coil type of edgewise switchboard AC voltmeter. Popular style used on switchboards where many meters needed to be stacked vertically. Switchboard voltmeters were widely used in the electric industry at the turn of the century. This form appeared before the turn of the century and remained popular for decades afterwards. Since the diamond-shaped pointer is far from the scale, parallax errors could be quite large.
