SIGMA ELEKTRIK SAN. VE TIC.LTD.STI
Digital voltmeter is used to measure the AC voltage that goes through the meter on
its ring circuit lt also can de used in other working condition that is on the purpose of
voltage measuring. The max value of the instantaneous conveyance voltage should
not exceed 600V The working power supply input terminals (3-4) and the measuring
signal connection terminals (1-2) are on the back board of the meter and the display
screen is on the front panel.
