EQtri - Multi Voltmeter


Features
- For measurement of AC voltages
- Exchangeable dial
- Enhanced resistance to mechanical vibrations (option)
- Protective cover for terminals (option)
- 6-position switch (phase against phase, phase against N)
- LED phase indicator and sequence indicator (option)
Application
This instrument type is used for measurement of voltages in threephase networks. It can replace three voltmeters or external voltage change-over switches.
Optionally it can be equipped with a phase sequence indicator/ phase voltage indicator:
If all three phase voltages are present and if the phase sequence is correct (right rotation), the green LED of phase sequence indicator is lit. If all three phase voltages are present and if the phase sequence is changed (left rotation), the red LED of phase sequence indicator is lit. If one phase voltage is absent, the rotation field is not more complete and both LED’s are lit with reduced intensity. The phase indicator is realized by 3 additional red LED’s
