🔍 Key Concepts

• Megger scale units: Notice that the left half of the upper arc is labeled in megohms, while the right half is labeled in ohms. • Reading by position: The numbers 1–9 along the bottom are reference points. Each one lines up vertically with a mark on the resistance scale above. • Unit conversion: Remember that 1 megohm = 1,000,000 ohms, so compare the answer choices’ units (ohms vs. megohms) with the part of the scale you’re reading.

💭 Think About

• Is position "3" located under the megohm side of the scale or the ohm side? What units should its reading be in? • Which labeled tick mark on the upper scale is directly above the "3" position, and what number is printed nearest that tick? • Looking at how the values increase or decrease across the arc, what approximate value should you expect around position "3" compared to positions "2" and "4"?

✅ Before You Answer

• Verify whether the pointer at "3" is on the insulation resistance (megohm) portion of the scale, not the low-ohms portion. • Confirm the exact printed value on the upper arc that aligns with the "3" mark before matching it to a choice. • Make sure the choice you pick matches both the numerical value and the correct unit (ohms vs. megohms).
