[Test-Equipment] Evaluation of two DMMS

[Al Parker]

hi John,
	I hope things are well with you and Barbara "out there".  Maybe not so 
hot a July as "back here".
	A man with a watch knows what time it is, a man with 2 watches is never 
sure.
	If you switch batteries in the 2 meters, does the same one still read 
off?  Particularly the low range depends a bit on the battery voltage 
and ability to hold a current drain.
	On the next higher scale, do they read a test resistor close to the 
same?  (doesn't really matter  what the actual resistance is.)
	It could just be that the resistor for the low range in the "bad" one 
has had too much current thru it & is off value.
	Just some thoughts.
	I've just started on an SP-600 to be delivered at Shelby, hope there's 
enuf time.  Same fellow I did one for 4 yrs ago.
73,
Al
