HITACHI VC-7504 oscilloscope.
I bought it few months ago and I was very pleased with it.
That until yesterday evening after three weeks in which it was not used, it was not put in the plug and it does not want to work anymore.
At startup, it does some kind of test, some sort of self-calibration, gives PASS to all the functions that check it, displays the message that it has finished calibration and then hangs there. Mut!
If I stop it and restart it, it does nothing, it does not display anything, it does not respond to any commands.
Self calibration, before when it worked, usually did it after a long time in which it was not used. It started working but displayed a message with a "emty battery" for a while.
I think it was some BIOS battery.
I opened the tool, I identified the battery, 1.2V at the first measurement and after a while in the socket ... it reached 2.27V.
Is it possible because of that battery to remain hanging after doing his test .... Has he lost some necessary data when booting and does not know what to do?
The oscilloscope is a combination of digital analog and crt. I liked it very much and I would love to save it.
