Greetings, I recently made the same mistake on my es585 haha (tested a bug zapper that I misread the joules as volts xD. I have now found that my 27m2c is heating up and likely fried as I get no input on the screen or beeps. I was wondering, did you buy a replacement for it? If so which, as I cannot find the exact one for the life of me, the closest I found is this but my unit uses a 27m2c 96m a3n7 which doesn't match any online listings. I look forward to your reply.

Regards,
Zachary.

Hey John,
That's great news. Age does have it's advantages at times.
Instead of getting into something that we think we should be able to do, it's good to realise our limitations, understand that we don't know everything, listen to advice from others and then slowly increase our knowledge to a level that we feel comfortable taking on a new project.
That takes time and wisdom, something I would gladly tell my 'younger self'. 🙂

In reply to Mark.

No problem Mark. I hope you'll discover what its function is in your DMM. And maybe write about in your next DMM repair? About the mentioned 6 to 1 Mux, it would only need 6 different selection values to address any of the six inputs individually. So to be exact we only need the 6 values 000,001,010,011,100,101.
Because although 110 is 6 decimal it already would be the seventh selection value counting from 000 that is not needed. Or if '000'is used for instance as Reset or Z output activation (Z impedance,so not low or high neither, ideal for connecting to heavily occupied databus traffic) then all 7 values 000 upto to 110 binary would be used. Cheers!

I admire your capacity for trying something. I have destroyed numerous meters in the past and thought... Do I need to repair this or replace. NowI am older I repair rather than throw away.
Good work.

Hey Albert,
Perhaps they should have named it a 'multicomplexer'! 🙂
I am only learning about the complexity of IC systems, but find it fascinating.
Thanks for the extra information.
