I downloaded the Scope of Accreditation document for the above lab.
Am I interpreting things incorrectly, or do the uncertainties for DC
voltage source (in particular) look large?
One very odd thing that I noticed when it was open was the remnants of a
wire that had been tack soldered to what looks like a voltage regulator.
Looks like someone either wanted a temporary test point for the
unregulated 5v supply while they troubleshot a problem, or used the
unregulated supply to power some modification that has since been
removed. Kinda sloppy the way they left it.
Best regards,
Charles
