Hi..
My dear Philips/Fluke PM3070 oscilloscope has a problem.
Normally it stores the values of the voltage scales, time scale and other things when i switch the PM3070 off. When i switch the pm3070 on again the settings are restored.
But since a few days the settings are not restored. The PM3070 now starts up with no A and B channel visable. I have to push on AUTO SET to get them back. Then every thing seems to work again.
Fluke told me in some PM3070's are two penlights batteries inside. But i do not see them. And i can not see any other battery. Here are several pictures of the inside
What could be the problem ? How to solve it ?
Thank you very much.
