I have hacked this meter so that it can be with
Variac 10A AC Power Auto Transformer 0-130 VAC w/ Meter,1000W Voltage Regulator
( I have seen on You Tube where people have put digital meters on a Variac but all the one I seen they have where the volt meter can not read the voltage below about 80 volts I did not mine to work this way )
Which is something I going to buy soon
How I figured out where the voltage input was I had decided to replace all the caps on the board top board with all the caps remove and high powered light it fairly easy to trace where the traces go
So I traced wear all the input power went and found all you have to do is remove a surface mount diode ( M7 )
and replace it with a 1N4007 and on the side of the diode that has the line is where you put the wire so you can measure the line voltage of the Variac out put
