content: What a "P"ain "I"n "T"he "A"rse that was to post! I had saved a single photo of my 289 somewhere and then a few somewhere else. Do you think for the life of me I could get the link to the ones I wanted to post? Me and anything that can be a pain in the arse usually end up in a serious war of attrition...… I should learn to give up earlier and stick my photos up my arse and sulk!

content: It's not too hard once you know how.Any one file can't be larger that 1 Mb.You're only allowed a total of 2 Mb/post.Use your photo editor of choice to compress pics to a size relevant to the detail youneedto show. 100 KB is usually heaps enough detail.Add them individually into the 'Attachments" UI below this posting box but take note of the file types allowed.Then they're displayed as thumbnails that you can copy their URLs and place between in [ img ]image[ /img ] tags available from the Insert Image icon.Sometimes for a few images it's easier to open dual tabs, editing one with URLs copied from the other.

content: Quote from: coromonadalix on July 21, 2018, 03:50:39 amYes it's original, I certainly haven't changed it and although I bought the meter from an ebay seller i'm sure it was brand new when it came to me.A huge chance I know, buying from Ebay. Sometimes you have to just grab your nuts and jump though, right? The price was sweet and the feedback was recent and good and everything seemed cool so I went for it. I've had it around 6 months now and all seems good..... I shouldn't have just said that right? It will likely blow up tomorrow now! DAMN!! LOLThat's a good score on the Panasonic ones. I may invest in a couple too just as spares. Always good to have and at a quid or 2 you can't go wrong.

content: An alternative is to use CDE Cornell Dubilier type ELDR ultracap, it has the life of 2000 h at +85ºC, much longer than Panasonic's one.Need abit of tweaking by bending it's pins, but its not that difficult, example ->Result by other memberDigikey ->https://www.digikey.com/product-detail/en/cornell-dubilier-electronics-cde/EDLRD224H3R6C/338-3477-ND/3986805
