Would a small UPS, running on batteries, be a suitably stable 230v 50hz supply while I do some tinkering with the loop calibration settings on an old Robin 1610?
Any better idea's that don't cost a lot?
This is entirely a hobby project and not worth investing in lots of equipment for,.
My copy of the service manual (which looks as though it was typed onto toilet roll and then faxed from Australia via a piece of wet string) seems to suggest that as it's an old-school tester I can do most of it (not RCD stuff) with a stable power source and a decade box., making adjustments to 5 variable resistors.
Knowing the supply loop impedance is usually required, though I'd guess the N-E link on the secondary side will make that almost negligible.
