What to Look for in a Multimeter for Electricians
Before you buy, you need to know what specifications actually matter on the job:
- Safety rating: Look for CAT III or CAT IV rated meters. CAT III covers residential panels, and CAT IV covers service entrance equipment.
- True RMS: Non-linear loads like variable speed drives and LED lighting require a true RMS meter for accurate readings.
- Auto range: Auto-ranging saves time because the meter selects the correct measurement range automatically.
- Backlit display: You often work in crawl spaces or dim electrical rooms where a bright backlit display makes a real difference.
