Also, this device can be called: M-42276, M 42276, m42276, m-42276, m 42276.
Ammeter, voltmeter, ammeter, milliamp, millivolt, kiloampermetry, kilovoltmeter M42276 - devices-coil system for measuring current or voltage in electrical circuits, DC.
M42276 devices - with removable scales. Change scale (without opening of the instrument) is a groove in the upper housing.
Measuring gear units consists of a movable coil (frame) and a cylindrical magnet disposed inside the frame.
M42276 principle based on the interaction of the magnetic field of the permanent magnet with the electric current passing through the winding frame.
The devices are characterized by a dial indicator, mounted on the moving part of the cores or banners, uniform scale, a zero mark in or on the edge of the measuring range.
