Handheld Oscilloscope, 97 50MHz FLUKE SCOPEMETER Troubleshooting
I tried repairing a broken portable oscilloscope.
This is because the rechargeable battery has reached the end of its service life and has not been charged.
However, when I opened the cover of this, it was caused by corrosion of the electrode of the power circuit due to battery leakage. I did not complete this, but I cleaned the corroded part of the electrode part (blue) with a metal brush and charged it with a charger for 2 days.
When I turned on the power switch and checked the operation status, it worked really well.
wow!
It filled me with the confidence that I had accomplished something with my own hands.
