Fluke 8842A ROM binary

If you get no help here you could try joining the Tech Tools mail list and posting there. Email me for the link - a small group of video/pinball techies that help each other out with test gear.

I suspect there are Fluke forums out there though that might work better.

I don't have the meter in question.

Hi Jay,

Did you ever find a copy of this ROM? If not, I have an 8842A and can copy the ROM. I am in need of a copy of the 8840 ROM if you still have it.

Regards, Tom

Correction: Actually the readings were off by a magnitude of 100.

Hi Tom,

Yes, I still need it. Check your email, I sent the 8840A binary to your valid email address. You can send the binary to my Yahoo account.

Thanks, I'll be glad to get this meter off my repair shelf.

Hello John,

I am jumping in here to add to Jay's request. He is working on a 8842A. I have a 8842A/AC and sent him a copy of the ROM. Unfortunately, it did not work as mine was a different version. He sent me the code for the 8840A but it did not work either as the unit I have is the 8840A/AC.

Bottom line is we are both looking for ROM images for different versions. You mentioned the tech group that may be of help. Could you let Jay or me know that info? My address is tmiller - at - skylinenet . net.

Best regards, Tom

Hi Tom,

I just did a binary compare between the ROM that was in my 8842A and the binary you sent me. They match. So it looks like my ROM is not bad, but somebody has been screwing around in this unit before I got it. I suspect that the micro-controller was swapped, and that the one that was put into it is a incorrect version (It is marked V2.3)

The spare piggy-back Z8 I have lying around also has a V2.3 ROM installed on it. If you can find a Z8 I could send you the matching 2.3 code that goes into the 2732 chip, giving you both a U222 V2.3 and a micro version

2.3. If your meter begins working then that would go a long way in figuring out whether the code in both chips must be the same revision.

Hi Jay,

I started a thread up on the Tekscopes group about this topic. You might hop over there and add to the discussion. It seems there are several versions of the Z-8 firmware and they don't match the EPROM versions.
