[size=10pt][b]2) I started in front of the first "A" of text "DALLAS" ... this is where is located the pin 7 of IC
(Luckily the DS1218 is a old DIL8 case with his large pins which will makes research easier)[/b][/size]

[size=10pt][b]3) Carefully I came down and widen the hole very near of case until i seen the copper appear
(It's the good moment to measure the internal battery voltage between this copper and pin 14 of the NVRAM)
Then i widened it enough to be able to solder a wire[/b][/size]


[size=10pt][b][color=red]Maybe a piece of advice : do not widen it too much on the side of the "D" and "L" of dallas so as not to short-circuit, with the dremmel head, the pins 7 with 6 or 8 of DS1218 because I don't know if that could kill it?.. [/color][/b][/size]

[size=10pt][b]4) I cut the branches of my socket to be able to easily pass the wire
Then I soldered two wires:
- positive on pine 7 of DS1218
- negative on pine 14 of NVRAM[/b][/size]

Hello Joseph,
Did you remove the internal battery before / after adding the external battery?
The Test 04 fail probably means your calibration data is corrupt, and once you have replaced the NVRAM, you have to recalibrate the 'scope.

Joseph: GREAT JOB!

The Dremel tool friction can create static electric and stress the potting compound. After the fine repair did you cover the holes with some sealant to ensure its airtight?

Enjoy,

Jon

PS: The DigiKey DS1227 are only $20, with fresh date codes and battery saver feature, they should last 10-20 years

NO ... It is impossible to disconnect the internal battery. The external battery is simply connected in parallel
The advantage is that if one day we have to replace the external battery, the internal battery will keep the data during the short operation it will take

I don't see the necessity to seal the hole after the operation because the pin denuded became a simple pin same at all pins of IC DIL8 existing on the 2465B board who are never sealed

For cancel all brackets I need to edit the message ... how do it?

 

Im sorry, I really don't know.  I recognize what is happening but I don't know why.  Its a function of the software you use to write messages to us.  Can you tell us what you use to compose and edit your messages?  Does it have a "clear text" mode of operation?
