[Test-Equipment] Manual HP 403B AC Voltmeter

[WA5CAB at cs.com]

Harry, et al,

It is a bit strange that the only TM on the site is the -34P.  Which is the 
Depot and some other things Parts List.  However, when trying to use LOGSA as a 
source, it helps a bunch to become a little familiar with the TM numbering 
system.  "P" on the end of the string means Parts.  The two digits before it (or 
the last two digits if no "P") are related to the level of technical detail 
you may find in the TM.  I've seen a couple of exceptions (there always are) 
but in general that only long number TM 5, 9 or 11 that will have real (as 
opposed to changing fuses and air filters) maintenance info will end in 14, 15, 24, 
25, 34, 35 or 50.  And not in P.

Also, as a general statement (with exceptions), most systems have a set of 
manuals but individual major components of the system may also have their own 
set.  If this is the case, the info we usually expect in a "maintenance" manual, 
like schematics and so forth, will only be in the individual set's depot 
manual.

Foregoing only applies to long number series TM's.
