Where do I buy a multimeter?

A multimeter is only required for Turo inspections. If you're booked for a Lyft or Verida inspection, you don't need one. See "What are the battery requirements for Turo?"

You can buy a multimeter at most AutoZone, O'Reilly's, or other auto-parts stores, if available in your area. Here's an Amazon option: https://amzn.to/4cKTkiN

Note: for Turo inspections the battery must be tested during your inspection with your inspector watching. A report from an auto-parts store isn't accepted.
