VIS 210F 12.6 12.9
BASE NUMBER NR 3.6
OXIDATION 39% 30 abs/cm
The first lab did not report on Base Number, and reported Oxidation as a percentage. The second lab gave a base number of 3.6, and Oxidation of 30 abs/cm, whatever that is.
I have seen VOAs for DT40, but they didn't include oxidation, and I understand you need to understand the start number of the oxidation to understand the number after usage.
Can anyone tell me more about my oxidation numbers or know the start numbers for DT40?
