Review: Great for 90% of diagnostic situations and good value! - Love this thing. Had it for about a year now and if it had transistor Hfe and capacitor ESR it would be the perfect piece of diagnostic equipment. So much more convenient than having to switch between a multimeter, a bench scope, and a logic probe back and forth. Battery holds a charge for a long time too. Bright, high-contrast screen. Only complaint is the auto-screen-shut-off is set to like 5 minutes out of the box so it will spontaneously "turn off" on you while taking measurements. You can change this in the menus but it is not the same thing as the Auto-Power-Down feature, which is confusing.
Review: Very happy with purchase - Excellent quality. Be sure to update the firmware to V1.4.2. Once updated the scope trace will appear much finer in detail. Plus a new feature is added to the menu.

### ⭐⭐⭐⭐ Well Built, works well for basic troubleshooting, room for improvement
*by G***S on September 18, 2024*

This meter is well built (solid, but not rugged) given the price range. The meter meets all it's claims and is accurate on par with any sub $200 meter. It's oscilliscope functions are okay (a little on the slow end) but work well. My only real gripe is that the oscilloscope does not have (anywhere that I could find) a maximum voltage rating for the inputs. Other than that, the recessed BNC connectors can make attaching and removing probes difficult as the part that rotates of partially blocked by the meter body. (that isn't a serious issue, and I appreciate the protection the recessed sockets provide for the connectors. In solving this I would suggest providing either extenders or leads with better grips on them.) Overall though, if your looking for a decent portable meter & oscilloscope for car/hvac diagnostic purposes and don't need/want to buy a Siglent or Fluke/Testo then this is a good meter, especially given the cost!
