Example of early 20th century D.C. switchboard meter used in Quebec power industry.

Function

Change to: Measures DC current of battery charge/discharge in Amperes.

Technical

Permanent magnet movable coil type DC fan-shaped switchboard ammeter. Fan-shaped instruments are designed to have very long scales while keeping the case compact. This is useful when the range of expected measurements is wide. Weston claims that its fan-shaped meters have the longest scales in the world relative to their size. This switchboard meter could have been mounted on a panel for battery charging and use. It would be connected to rheostats along with a voltmeter and help to charge batteries without overloading them. Scale has 0 to 25 in positive and negative. This artifact is a duplicate except for the scale of 1969.0161.
