Video Summary & Review
Is the Harbor Freight 7 Function Digital Multimeter worth your money? At just around $8, this is one of the cheapest and most common meters on the market! 🛠️

This video is a comprehensive tutorial and review of this manual ranging multimeter. We walk through every function, explaining the critical concept of resolution and why manual ranging meters require you to "zoom in" to get accurate readings [03:06].

A standout feature is the unique battery testing function which displays remaining charge in milliamps—a major benefit not found on many expensive meters [05:23]! While it has some drawbacks (no backlight, manual ranging), it's a feature-packed tool for the price.
