A teardown of Amazon’s cheapest multimeter the DT-830B by Electronupdate:
Purchased the cheapest multimeter I could find so I could extract the integrated circuit. A surprisingly simple IC!
The actual meter design was much as expected. Poor attention to detail for higher voltages, concerning lack of fuses on current measurements… pretty thin feeling probe set.
Attractive die however!
