I would really like to have a go at building one of these sometime.

One question, with the inclusion of a preset resistor, is an existing separate reference voltage required to adjust the unit?

I haven't got a reference at the moment but I need to measure a 12 volt rail in a vintage oscilliscope accurately.

Is there anyone local(ish) to Walsall who has a calibrated DVM that I could compare my thirty year old BT Digital to?
