Hi Folks,

I use a 4.5 Digit DMM for most of my projects as I supermatch 1 % resistors
for my own DACs.

The next time I buy a DMM I want to go to 5 1/2 Digit for even tighter
measurements on some things I am working on.

Use a Tektronix 465B and 475 Oscilloscope for audio projects. Digital
projects I go into the Lab and get much better gear.

Regards,

Terry
