content: Greetings all!If this is the wrong location for this question please forgive a first time poster. I have recently developed a need to use and have some understanding off DMM's for PC diagnostic purposes (PSU issues). After much Youtube time and questions of educated folks I have decided not to retrieve my $20 Digitech DMM from the trash where I tossed it after an internal inspection. I realise the Digitech would have been fine for working with PC PSU outputs but to quote Dave "its just shit!" hence I am feeling the need to purchase some quality. Namely a Brymen DMM specifically,Brymen TBM682 AUTOCHECK.Planning to purchase from (after prior approval by the minister for War and Finance!)http://www.coolice.com.au/catalog/product_info.php?cPath=863_716&products_id=7722&osCsid=f6d544a5ab605c1b52a6ca25c4377bc5I am hoping that some of the folks on this forum might let me know if this DMM follows the Brymen tradition of quality etc and would be a worthwhile purchase (certainly seems so).Thanks all

content: This meter is also made by Brymen for Greenlee. A teardown is shown and should be close to the one you are interested in.Greenlee DM-300Obviously, the meter has no current measurement.If you are interested in Brymen, for $135 USD, you can get the Brymen 257 (bigger display, backlight, more features, current measurement) from a forum member here. Dave also has a video of Brymen meters.PS. If you are only working on the secondary side of a PSU, the Digitech should be fine. It is only if you have to measure ACV or DCV on the primary side, then you have to worry about 240VAC and/or close to 400VDC.edit: Link to Franky's auction.http://www.ebay.com/itm/200922627340

content: Cheers RetiredcapsI have been looking at the BM257 for some time now (have had that Ebay seller you linked to in theFavourites for several days) and I really think I "need" one! My interest in the Brymen TBM682 AUTOCHECK was based more on the brand name and the price tag (not to mention sliding it past the financial controller). When it gets right down to it I most assuredly can work with the now absent Digitech item but I just prefer nice gearAs far as working with PC PSU, you are 100% correct I am only interested in the secondary side and most definitely not qualified to be opening the box so to speak!Thanks for taking the time to help educate me it is much appreciated

content: Ahhhh the crux of the problem and that is, the difference between NEED and WANT!!Frankys eBay price and postage is so good that with a little patience I shall make it mine.The BM 25# ticks all the boxes for me in fact they far exceeds my requirements. However several things make them attractive, firstly the price is about right for my budget they are well made made. Have features that I would otherwise not have had that I will use for example the temp probe and the NCV detection not to mention that rather nice looking display. Another selling point for the BM 25# is that I cannot find a bad review of them, with my low level of knowledge that becomes an important selling point so all in all I think my interest in the Brymen TBM682 was just a diversion and I shall have to save slightly more for the BM25#.Thanks again for the advice and suggestions as I said earlier I really appreciate the effort!

I forgot to mention that some Amprobes are also ODM by Brymen. And at least one Sanwa is a Brymen.https://www.eevblog.com/forum/testgear/amprobe-(bryman)-am130-teardown/https://www.eevblog.com/forum/reviews/sanwa-pc-510a-dmm-mini-review-teardown-pics/That should give you lots of options to find a Brymen (new or used).
