🔍 Key Concepts

• Three-phase phase sequence (rotation) testers and what they look like • Difference between general-purpose multimeters/clamp meters and special-purpose indicators • How LED indicators are usually arranged for simple yes/no or direction (ABC/CBA) displays

💭 Think About

• Among the instruments shown, which one appears to be designed specifically to connect to all three phase conductors at once rather than measure just one value at a time? • Which device looks like it would give a simple direction/sequence indication with lamps, instead of a numeric voltage or current reading? • Which of the options listed (B, C, D, H) is clearly not a standard multimeter or insulation tester but a dedicated three‑phase accessory?

✅ Before You Answer

• Verify which instrument has three identical leads or clips clearly meant to go on three separate phase lines. • Eliminate any instruments whose primary display is LCD numbers or an analog scale instead of LEDs. • Confirm that the remaining candidate is a small, portable, likely battery-powered phase sequence tester rather than a full-size meter.
