test station

Hello
I received my station the day after my order and I could not resist the test.
Retired after 42 years spent in troubleshooting various electronic equipment, I made the mistake of selling my hot air station.
Needing to repair an electronic computer car, I ordered this station.
To my surprise she gave me the same service as my old job for a price 10 times more expensive.
In one troubleshooting is depreciated.
I put you a picture of a trial.
