Analogue instruments with scales
The range of mono-function analogue instruments, employable in single-phase networks, is composed of measurement
devices performing the measure and visualization of one electrical parameter: voltage, current and frequency.
The range of voltmeters, both in modular and front-panel versions, is composed by devices fully equipped with the proper
scale, even when the use of a voltage transformer is required. The connection, whether it’s direct,
allows the immediate visualization of the measures on the display.
The range of ammeters is composed of devices for direct and indirect connection to the network. The devices directly
connected to the network are fully equipped with proper scale, while the devices that require a current transformer or
a shunt, need to be combined with a separate scale to be mounted on the front of the instrument.
The wide range of scales for ammeters allows the employability of the latter even in application with high nominal current,
up to 10000 A a.c.
