Etching

Test etching.











Some work to do on the quality of printing and laminate photo transfer timing.

Fluke 12E+ Modification

A wee upgrade in the works today...

New functions:

Min-Max, Delta.



Hz, Duty Cycle.



Degrees C (via thermocouple) needs extra circuitry including calibration ROM.

UNI-T Scope SMPS Repair

The PWM chip had developed a short, and the one-hung-low caps looked dodgy.



Rubycon Caps and new IC fitted.



Repair tests.



All replaced and working perfect.
