Here is finally a teardown of my UNI-T UT70A. Photos were made by me in 01/2010. UT70A was bought in 12/2009. At this time it was one of the few cheap DMMs with L measurement capability. It has many functions for the price.
Input protection of the Voltage input is so-so. There are PTCs and probably MOVs, but no spark gap. Back in 2009 I did not care about CAT rating. There are three 250V glass fuses.
There is an external fixture for transistor testing.Backlight is quite crap.
