Whats wrong with the CDE cap that I proposed earlier at post #38 ? DK part no 338-3477-ND and its available.
Panasonic cap is not even in the same league when it comes to reliability and long term life compared to this one.
Though you will need to bend it's pin to fit in the foot print, but not a big deal imo.

Ah, I forgot. That's one reason I thought it might be better to put a summary of such information in one place. When it's spread out over several pages in a thread, things can get lost.

60000uf is only .06F, about 30% as much capacitance as the original.

will it affect the performance of the meter? i have the same cap stocked on my bin and i thought of using it to replace the bad cap on my meter..

No, that cap's purpose is just as a backup power for the dmm's clock & calendar during the batteries swapping period.
Not a very serious problem imo, especially you rarely use the logging feature.
Just make sure the new replacement cap has low leakage, other wise it will drain the batteries power even its powered off, as the example of the original cap does when its deteriorated. :-[

I think it’s not a problem to leave it out, if you don’t need the clock and calendar when swapping batteries.
