[Elecraft] Calibration Standard

[W3FPR - Don Wilhelm]

Steve,

I don't have a direct answer to your question - I do believe that
information is old and tha actual voltage depends on the battery type
(zinc/carbon, alkalyne, etc), BUT ---
Look on my website www.qsl.net/w3fpr for an easy to build calibrator for
your DMM.
