Hi guys, many members discuss EDC equipment here, so I have one MV105 with galvonometer that not work, with the schematic of MV106 found here, has galvanometer schematic, but I don't Know if is right, first, the input is grounded.
Second, setup instructions says, short circuit on input to calibrate FS in 10V, so everything is grounded, turn the trim-pot and nothing.
Someone can help, someone has Galvanometer to share information, schematic, pics, etc.
