Blanknut differences Message #1 Posted by Casey Drew on 28 June 2010, 4:45 p.m. Hi, I just acquired an HP41 Blanknut. I was wondering what is the easiest way to confirm if it is the Model 41C, 41CV or 41CX. There is no model labeling on the unit. Thanks!

A C/CV doesn't show any CAT 2 entries. To check for C vs CV, do SIZE 100 , then RCL 99. If no error (either in SIZE or RCL), it's a CV. HTH Raymond
