Re: [vintagesynthrepair] decent meter for negative voltages

2004-09-12 by John Brewer

I'm not sure what method you have to use to set up. If you have an ordinary
meter, can't you just put the -ve of the meter on the -5 point and the + on
the 0v line to measure the -5 and then move the probe to the +5 point where
it will then read 10v. or have I misunderstood your problem.  I use a Fluke
75 iii multimeter which is excellent and will measure + and - without
changing the leads over. It just flags up a minus sign in front of the
reading.  I am not sure of the price but I think it came from Farnell.(sorry
about the plug.)
