I will assume we sufficiently answered your question and in future queries a common reference might be an edition of the Lineman and Cableman's Field Manual ISBN: 978-0-07-162122-9 (2nd edition) or related occupational manual?

BEST!

Sufficiently would be a bit of an understatement.. Many of the solutions suggested here are a lot more advanced than I understand. The main problem for me is that my class uses some Casio calculator and the tuition is based on that calculator, this means I have to figure out how to do the same things on my own. Guess that`s what i get for getting addicted to RPN..
I see there was a bit of confusion as to whether i needed accurate or close fit, honestly I'm not really sure but i believe accurate fit is what I'm after. Thanks for the tip about the Field Manual btw
