Re: Tek 2430 Oscilloscope self cal not working
|
The 2430 and 2430a have battery backed ram. Either with a static ram memory with a Li cell or a Dallas nvram with internal cells. If they are dead, the cal will not complete.

One initiated, the display "running" appears, but instead of running for approx 10 secs it stays running.No errors or fails appear. Because no "pass" is achieved the scope won't operate. Manual states " return to qualified personel for service" in this case! What could this be?
