Data Precision model 1350 DMM teardown & repair

[intabits]

A teardown and repair of a Data Precision 1350 digital multimeter.



It's a 3.5 digit from the "budget" end of DP's product line.

After some initial stumbling around trying to make sense of internal voltage readings, and chasing down a couple of dead ends, I finally
find the problem.

Total cost for unit and repairs, under AU$20, not a bad result.
