🔍 Key Concepts

• VRM (Variable Range Marker) purpose on a radar display • Relationship between VRM and fixed range rings • How technicians verify that the distance shown by the VRM is actually correct on the screen

💭 Think About

• Ask yourself: what does a VRM actually show you on the screen, and what "known" references are already available there to compare against? • Which option describes comparing the VRM to something that is already calibrated for both near and far ranges, rather than only one point? • Think about whether you would want to check accuracy at just one range, or at more than one point on the display.

✅ Before You Answer

• Identify which choice talks about using known, fixed references on the screen to check the VRM. • Check which options rely only on oscillator frequency wording without clearly tying to a visual distance check. • Make sure the method you pick would confirm VRM accuracy at both close-in and far-out distances, not just at a single range.
