🔍 Key Concepts

• A megger scale often has two outer scales: one in megohms and one in thousand ohms (kΩ). • The pointer position marked "7" must be matched to the correct outer scale that the question is asking about. • Remember that 1 megohm = 1,000,000 ohms and 1,000 ohms = 1 kilohm = 0.001 megohms.

💭 Think About

• First, decide whether the reading at position "7" should be taken from the megohms scale or from the thousand-ohms scale based on how the graduations are labeled near that point. • Look very closely at the markings just above and just below position "7". Which labeled tick marks does it fall between, and are those values written in megohms or thousands of ohms? • Once you identify the approximate value on the correct scale, convert it if needed so you can compare it directly with the answer choices.

✅ Before You Answer

• Be sure you are reading the same side of the scale (left high-resistance megohms vs. right low-resistance thousand ohms) that aligns with the position "7". • Confirm whether the value at "7" is closer to hundreds of thousands of ohms or to many megohms before picking an answer. • Double‑check that the answer you choose matches both the numerical value and the units (megohms vs. thousand ohms) of the scale at "7".
