3562A Analyzer
|
I've been restoring a 3562A analyzer for a couple of months I bought it off ebay relatively cheap as it had some water damage. It's working fairly well now, but I have a couple of startup errors, one I've tracked down to the A4 LO board. When I replace with a known good board the LO errors stop, but I keep getting a "Bad Auto Sequence Table" error on startup and I can't find any reference to that error in the manuals I have. Anyone familiar with this error and have an idea which board might be the cause?

That message is usually caused by the A2B1 3.6V Lithium backup cell on the A2 CPU board needing replacement.... Regards. Ron Wilkinson mi-Biz Systems Pty Ltd Perth - Western Australia ==== ChuckA wrote:

I did replace the backup cell, in fact one of the first things I did. I'll check the battery again and also make sure I didn't move the jumper to the test (disconnected) header pins while I was testing the unit Thanks Chuck On 12/29/2012 12:47 AM, Ron Wilkinson wrote:

It was the test/normal jumper, guess I moved it after I set the unit aside and forgot to move it back. Chuck On 12/29/2012 12:47 AM, Ron Wilkinson wrote:

That's good news. I've seen various of these units with that message and it's always been an issue with the backup cell (or the test jumper)....! Best regards, Ron Wilkinson mi-Biz Systems Pty Ltd Perth - Western Australia ==== ChuckA wrote:
