PURPOSE OF THE VOLTMETER
 Digital industrial voltmeters VR-M03 and VR-M03-1 are designed for technological control voltage value in electrical power circuits of alternating current, as in the industrial areas, and the housing sector, household sector, other objects of the national economy. It can be used as part of automated control systems and process control as the main or additional display on mobile and stationary objects. It is a mean of control. Periodic calibration is not subject.
 
DESIGN OF THE VOLTMETER
 Voltmeter is produced in a plastic case with a unified front connection wires power and switched circuits. Mounting is carried out on a DIN rail  width 35mm (GOST R IEC 60715-2003) or on a smooth surface. To set on a smooth surface, you need to push locks. Terminal design provides robust clamp wires up to 2,5mm2. On the front panel there are three digit seven-segment LEDs in red color, that showing a value of voltage in each phase. The voltmeter provides three galvanically isolated measuring circuits (only VR-M03).  Voltmeter, according to the connection circuit, may be used to control the voltage in the independent lines or three-phase nets for linear control or phase voltages (only VR-M03).
 
OPERATION OF THE VOLTMETER
 Voltmeter does not require auxiliary power supply, and connects directly to the measurement chain.
 To control the voltage in single-phase nets a connection of any input is done without regard to the location of the phase and neutral wires. To control line voltages in three-phase nets, zero bus should be connected to each input of the voltmeter. To control the phase voltage a connection of each input of voltmeter is made between the phases.
 If in process of work the voltage at any measured line falls to value less than 15V, actual value of the voltage at the display of corresponding line will flash with 1s interval. If in process of work  the voltage at any measured line greater than 450V, actual value of the voltage at the display of  corresponding line will flash with 1s interval.
 
 Voltmeter VR-M03-1 has a common zero and is used only to measure the three-phase phase voltage.
