Meters and troubleshootingQuestion 317 of 1506

A technician measured current with the red lead in the A socket. Then the selector was turned to V and the meter was placed across a 600 V supply. What is the likely result?

  1. A correct voltage reading on the display
  2. A reading of zero volts on the display
  3. A blown capacitor inside the meter
  4. A short circuit through the meter
Show answer

Correct answer: A short circuit through the meter

The A socket makes the leads nearly zero ohms, so the meter shorts the supply.
