Volt Voltage meter M42100, designed to measure voltage in DC as mobile and fixed installations.
Are resistant to shock and vibration.
M42100 devices are designed to work in vertical and horizontal positions. Calming time of the moving part no more than 3 seconds.

The design of the housings provides a degree of protection on the front panel IP50 or IP54, for live parts - IP00.

Attention! For measurements of voltages exceeding 600V, external additional resistances (resistors) are used.
With an external additional resistance with a rated current of 5 mA, you can connect a device for measuring an extended voltage range up to 3 kV
According to information from the manufacturer's plant.
"Use with an additional resistance for a rated current of 5 mA and R = 600 kOhm"
The power of the additional resistor must be at least 15W, for a nominal value of 600K.
