[volt-nuts] Current Button for Datron calibrator (4800, 4805, 4807, 4808)

[David C. Partridge]

I'm on the lookout for a button for a Datron 4800 series calibrator which
may be a bit of a long shot.

It's the one between the Ω and AC buttons with the Legend "I" (uppercase
i).

An even longer shot - my front panel is a bit bashed - has anyone got one
spare?

You never know someone may have a spares mule!

Also (Ho! Ho!) does anyone know the whereabouts of a complete Operator
manual (with the Verification and Calibration sections), and the Service
Manual for a 4808?

Thanks
Dave
