Introduction

Voltmeters measure the potential (voltage) difference of an electric circuit in volts.
For ammeters, the measurement is read on an interchangeable dial. The range integrates two device types: devices for flush-mounted installation and DIN rail
Common technical data:
accuracy: class 1.5
operating frequency: 50/60Hz
operating temperature: -25°C to + 55°C
for flush-mounted devices, two sizes: 72 x 72 and 96 x 96 
Heat resistance:case of non-combustible phastic material
