Originally bought as spares or repair. Now fixed up and working - mostly
just a matter of using known voltages and other meters to get the
references, zero point and turn over settings correct. Repaired a fault on
the sample/hold digital board as well.
Options:
30 GP-IB
40 Sample/Hold
50 50Hz mains supply (logic clocked at different frequency
to maximise 50Hz rejection).
Readings now accurate by comparison with 6.5 digit meter, but not formally
calibrated.
This beast is accurate and FAST - on DC will sample every 240mS. It is
also built to a standard which makes modern kit look totally shabby by
comparison, and is repairable!
I've not tested the GP-IB as I don't have a GP-IB card.
Based in near Warwick in UK.
If interested, please contact me offline at david dot partridge at dsl dot
pipex dot com.
I have hard and soft copy of the operations and service manual which will
come with it.
