Frequently Asked Questions

Is the Vpro850L any different from the WeePro digital multimeter?

They’re the exact same meter — the Vpro850L is the model number, and WeePro is the brand that makes it. Both listings I looked at have the same ASIN B0BGT8XT12, same 1999-count display, same 2-times-per-second sampling, and same orange insulated rubber case. So there’s zero difference between them, which makes your buying decision really simple: just pick whichever listing has the best price or fastest shipping.

Can the Vpro850L handle automotive battery and alternator testing?

Yes, absolutely. This meter measures DC voltage, so you can test a car battery at rest (should be around 12.6V) and check the alternator output (around 13.8V to 14.4V when running). It also has an audible continuity test that buzzes under 30Ω, which is perfect for checking fuses and wiring without looking at the screen. Just keep in mind it doesn’t measure engine RPM or duty cycle, so it’s basic automotive work only.

Which is better for a beginner: the Vpro850L or a more expensive auto-ranging meter?

For a complete beginner, I’d actually recommend the Vpro850L over a pricier auto-ranging meter. It’s simple to use — you just turn the dial to the right setting for voltage, resistance, or continuity, and the backlit display shows your reading clearly. The PTC overload protection keeps you safe if you accidentally probe the wrong thing. You can always upgrade to a fancier meter later once you outgrow this one, but for learning the basics, this is all you need.

Does the Vpro850L come with a battery and test leads?

Yes, it includes everything you need to start testing right out of the box: one 9V battery, two 80cm test leads, and two alligator clips. I like that they include the alligator clips because they let you clip onto wires hands-free while you watch the display. Just pop in the battery, connect the leads, and you’re ready to check outlets, fuses, or batteries.

How accurate is the Vpro850L compared to a Fluke meter?

Let’s be honest — the Vpro850L isn’t going to match a Fluke in accuracy or build quality. Fluke meters cost many times more and offer true RMS, higher precision, and industrial-grade durability. But for general household use like checking if an outlet has power or testing a car battery, the Vpro850L’s 1999-count display gives you plenty of accuracy. If you’re a professional who needs certified calibration, get a Fluke. If you’re a homeowner, save your money and get this one.

Can I use the Vpro850L to test live household outlets?

Yes, you can safely test 120V and 240V AC household outlets with this meter. It has an insulated rubber case and ABS material for safety, plus PTC overload protection that helps prevent damage if you accidentally set it to the wrong range. Just set the dial to AC voltage, insert the probes into the outlet slots, and read the voltage on the backlit display. Always follow basic electrical safety — never touch the metal probe tips while testing live circuits.
