This is 2 part of the TENMA 72-7745 multimeter product review. (Link to Part 1).
Here I cover the poor but usable PC logging software. Then I spend some time on evaluating the battery performance before a complete teardown. In the teardown I found that the PCB is actually for a UNI-T UT60E. If you want to know as much as possible about this meter or the UNI-T UT60E for that matter then check out the specifications listed in part 1 and watch both videos.
