What is the resistance reading at "2" on the megger scale shown in figure "A" of the illustration? Illustration EL-0044

Correct Answer: Option A — 40 megohms

Megohmmeter scales are logarithmic, reflecting resistance values across decades. In standard marine insulation testing per IEEE 45, major scale divisions correspond to specific multiplier points, designating '2' on the relevant decade arc as 40 megohms.
