Agilent 34970A errors and battery replacement

<< < (4/6) > >>

plantgrower:
Thanks for the offer I am in the UK. The eeprom programmers I looked at were in the low hundreds I don't know which programmer you have.

Waiting a few weeks wouldn't be a problem.

free_electron:
not all programmers know how to do the FRAM's.

that chip is small enough it can go in an envelope. i'll get you one. but like i said. it's gonna be a few weeks.

plantgrower:
Many thanks. I'd like to take you up on your generous offer please.

If the machine sometimes returns PASS on the extended self test is this indicative of the FRAM chip starting to fail or of a bigger problem with the DMM card ? It seems more likely to return PASS when it has been off for an extended period of time. When it  then starts to return FAIL it never shows PASS again until it has been off for an extended period.

Is it ok if  I pm you with my contact details ?

free_electron:
Hmmm. That is a behavior i have not seen yet...
Start with swapping the battery. It may not come out of reset properly ....

If that doesnt work ill send you a new FRAM.

I have those batteries as well, but shipping that to uk is going to be a nightmare...

plantgrower:
The machine gives three short beeps at normal power up and a long beep and then three short beeps when I run an extended test.

I've had the dmm unit out and checked the battery 2.9v and in good condition so I don't think its that. Its also a short cylinder that has two prongs one either side not three prongs.

This machine PASSed three times in a row this morning but none since ?

Is it possible the fram has just started going bad as I was told these machines were in use not that long ago or is the error likely to be else where ?
