Title: Eros Build Resistances Consistently Higher Than Called For
Post by: Sugar Man on February 12, 2016, 06:07:17 AM

Just finished my Eros and have the following resistances that are higher than called for:

2    85.4K   71K
4    74.9K   60K
9    46.6K   39K
10  46.6K   39K
12  74.9K   60K
14  85.4K   71K

A4, B4   .621K    *
A6, B6   74.9K   60K

C1  46.6K   39K
C2  75.1K   60K
C4  .621K    *
C6  46.6K   39K
C7  75K      60K

Because these measurements are more than 15% high, I thought I'd post before firing her up.

You're OK. When doing the resistance measurements you are mostly making sure there are no zeros where there should be a higher reading (and vice versa), that would indicate a miswire. Small variations like you are seeing usually happen because different DMMs react differently to capacitors in the circuit getting charged by the DMM's battery.

Thanks Doc.  Just like to be certain before venturing into the live voltage checks.  :o 8)
