Multimeter
A multimeter is a basic but essential testing tool used by electrical repair professionals to measure electricity. Think of it as a combination measuring device that helps technicians check if electrical components are working correctly. It can measure voltage (electrical pressure), current (electrical flow), and resistance (how much something blocks electricity). When you see this on a resume, it shows the person knows how to safely diagnose electrical problems, which is a fundamental skill in electrical repair work. It's sometimes called a "digital multimeter" (DMM) or "volt-ohm meter" (VOM), and it's as basic to an electrician as a stethoscope is to a doctor.

Example Interview Questions
Senior Level Questions
Q: How would you train a new technician to properly use a multimeter?
Expected Answer: A senior technician should explain safety procedures first, then demonstrate basic voltage measurements, continuity testing, and proper range selection. They should emphasize checking meter settings before each use and maintaining proper category rating for the job.
Q: Describe a complex electrical problem you solved using a multimeter.
Expected Answer: Look for answers that show systematic troubleshooting approach, safety awareness, and ability to interpret readings to identify root causes of electrical issues.
Mid Level Questions
Q: What safety precautions do you take when using a multimeter?
Expected Answer: Should mention checking meter category rating, using proper test leads, selecting correct measurement settings, and following proper measurement procedures. Should also discuss personal safety equipment.
Q: How do you verify a multimeter is working correctly?
Expected Answer: Should describe testing on a known voltage source, checking test leads for continuity, and regular calibration checks. Should mention importance of battery checks and visual inspection.
Junior Level Questions
Q: What are the basic measurements you can take with a multimeter?
Expected Answer: Should be able to explain voltage, current, and resistance measurements in simple terms, and when each type of measurement is used.
Q: How do you select the right setting on a multimeter?
Expected Answer: Should explain the basic dial settings, difference between AC and DC measurements, and importance of starting with highest range when measuring unknown values.
