🔍 Key Concepts

• Look for an instrument designed mainly as a voltage detector rather than a full multimeter or clamp-on ammeter. • Identify which device has a simple lighted indicator window that shows presence of voltage instead of giving a precise numeric reading. • Consider which tool would be carried by an electrician for a quick safety check before touching or working on a circuit.

💭 Think About

• From the illustrations, which device appears to have two test probes and a small viewing window intended only to light up when voltage is present? • Which meters in the figure are more complex diagnostic tools (multimeters, clamp meters, meggers, oscilloscopes) instead of simple go/no‑go voltage testers? • If you needed to confirm a circuit is live or dead before working on it, which pictured device would be fastest and easiest to use with a clear visual light indication?

✅ Before You Answer

• Verify that the option you choose clearly shows a lighted window or indicator rather than a scale or digital display. • Confirm that the device is primarily a presence-of-voltage tester, not an instrument for measuring resistance, current, or insulation values. • Make sure the device uses two probes and a compact body suitable for quick safety checks at a panel or junction box.
