Training to use DSN-DVM-568AC Voltmeter 70V~500V digital display?

How to use voltmeter DSN-DVM-568AC LED digital display two-wire AC head two-wire digital voltmeter AC220V mains 70V~500V?
In this video, we will see how to set up and install the Voltmeter 500VAC/DC dsn-dvm 568 ac, and for example, we will test the 220V and 110V AC power input with the voltmeter.
--------------------------
We also use a 7.5V transformer to show that voltages below 70V AC cannot be measured.

It’s lower because the amp of the led it takes

[@newtecpro]

Yes. But the amount of LED consumption is very, very low

How to change it to 3 wires?
So it can measure 0 - 500 Vac?

[@newtecpro]

No need for 3 wires. One phase wire and one neutral wire is enough. You can measure voltage from 70 AC to 500AC

[@jain461]

@@newtecpro I want use it on dimmer, when below 70 vac, for example 30vac, display voltmeter still on.

Not working for 12v

[@newtecpro]

That's right
