Broken calibration screw on mini-voltmeter

Hi,

I bought a DROK mini-voltmeter on Amazon two months ago. Yesterday, while calibrating it I broke the adjustment screw in the back, and now the voltmeter displays only 0.0 volt. I am not an expert in electronic, but I was wondering if I could just solder the connections where the screw was in the back and get rid of the calibration screw. please confirm if soldering connections could make the voltage reading possible again.

I have a picture of what I mean can I post it here?

You could try asking drok at http://www.cs.droking.com/2015/06/17/the-smallest-dc-voltmeter-only-0-28-led-display-and-measure-voltage-0-100v-with-mounting-ear/

I asked Drok, thanks.

Then try shorting all three pins together. Worth a try. Depends on the exact internal circuit. Use a very small soldering iron for minimal time.
