V-03
Purpose
The voltmeter of digital V–03 is used for measurements of size of tension in single-phase and three-phase chains of alternating current with a frequency of 50 Hz. The voltmeter digital is equipped with switches in the form of buttons, for possibility of a choice of the measured tension on phases. Measurement of linear tension between the chosen phases can be performed simultaneous pressing of two buttons.
Warranty period – 2 years
Design of system
The voltmeter of digital V-03 is executed in the case for installation on a DIN lath.
On the forward panel of the voltmeter are the digital indicator, LED indicators "L1", "L2", "L3" and buttons corresponding to them.
In the lower part of the block there are terminal blocks for connection of the block to a network.
Power supply of the voltmeter is carried out directly from a controlled network.

Preparation for operation and operation
Before operation it is necessary to study the maintenance instruction of the digital V-03 voltmeter.
To install the block in an electroboard on a DIN lath.
To make connection of an entrance controlled network according to marking (to Fig. 1.):
– for the single-phase L1 network – a phase, N – a neutral;
– for the three-phase L1, L2, L3 network – controlled phases, N – a neutral.
Section of the connected wires has to be 0,5... 1,5 mm of kV.
To make connection at the de-energized inputs of a network!
It is forbidden to open the block which is energized networks.
