Unitrend UT70A teardown
« on: May 11, 2016, 10:01:39 pm »
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.

The ut70a-complete pack.jpg photo was downloaded from http://arwill.hu/forras/kep/muszerek/multimeterek/ut70a-multimeter-602200-6640.jpg

There is a year 2000 mark on the case.

Well, I am quite satisfied with this DMM.
