Here's a tiny Teardown...to supplement the latest CHEAP-O Multimeter Review on the KJ103 SMART Multimeter (1.5 Star).
I had some folks request a few pics of the reverse PCB that I didn't include in the original YouTube Review.. so here you go!
The noisy surface mount relay is the PK-3 2A/30V...there's also a tiny PTC just below it (voltage protection). As well, the current shunt is located directly adjacent. Definitely a busy part of the board!
Also, you'll notice the lousy soldering job on those input jacks...they are barely hanging onto the board!
