Typical voltmeter used in Canadian industry.

Fonction

Measures small voltage in microvolts and decibels simultaneously. Used with NMA-5 radio equipment.

Technique

Weston permanent magnet moveable coil type. Small fan-shaped switchboard microvoltmeter mounted on support and connected to military type plug for convenient use with NMA-5 Radio set made by Stoddart Aircraft Radio Company. The meter is mounted at an angle without reducing its accuracy. This is possible thanks to innovations in the moveable coil mechanism. Many of the more accurate meters be almost or completely level to operate with the desired accuracy. Note that switchboard meters are usually less accurate than portable ones. Fan-shaped instruments are designed to have very long scales while keeping the case compact. Weston claims that its fan-shaped meters have the longest scales in the world relative to their size.
