🔍 Key Concepts

• Difference between a general-purpose multimeter and an insulation resistance tester (megger) • Typical insulation resistance test voltages (250 V, 500 V, 1000 V) and MΩ/GΩ ranges • How to tell if an instrument is battery powered and has a digital display from the illustration

💭 Think About

• Look closely at each of the four answer-choice meters and ask: which one is purpose-built for high-resistance insulation tests, not for everyday voltage/current measurements? • Check the control labels and ranges: which meter shows ranges in MΩ or GΩ and selectable test voltages, rather than amps and low-ohm resistance? • From the physical design, which instrument looks like a field insulation tester used on motors and cables, rather than a clamp meter or oscilloscope-style meter?

✅ Before You Answer

• Confirm the chosen meter has a clearly visible digital numeric display (not an analog pointer). • Verify that its scale or selector mentions MΩ or insulation test functions, instead of only volts/amps/ohms. • Make sure it is self-contained and portable (no hand-crank, clamp jaws, or oscilloscope screen), consistent with a battery-powered insulation resistance tester.
