The HP 3478A is a very good multimeter. Mine had not been calibrated in 5 years when I sent it to the cal lab earlier this year and it passed everything with flying colors.

Only drawback: the display has poor contrast. I wish there were an effective backlighting.

It is my most used bench meter, at home and at work, even though I really like the HP3456A too.

Looking for opinions on the HP 3478A multimeter.  I see them listed in 
the 100-200 U.S. dollar range for items in good shape, and right now a 
calibrated one for $170.  I like to stick to HP/Tek/Fluke so I can 
easily find broken units for a good price to get parts from and manuals 
are easier to get.

For my purposes (hobby and experimenting) it has more than enough digits 
and speed.  I like the high resistance on the low DC volt ranges.  It's 
not my only meter.  I have two Flukes from the 80's and a basic 
Tektronix plug-in.

What is the minimum I can get away with to prove/calibrate the DC volt 

Thanks in advance.
