Need universal meter

Hi, I need to determine if the motherboard on my printer is dead and have been told by the manufacturer that I need to use a universal meter. It’s a 150 lb UV flatbed printer so I can’t bring it to a computer store! Does anyone have a meter I can borrow or who can come test the printer for me? I live down South. I will be happy to pay for your time. Marie 512-619-7125
