1397010	2015-03-23 04:49:00	Hello, I'm looking for someone can help me on access to a excel xl830l meter or schematics that can be able to tell the mark value of the R5 from thew circuit board. This resistor (surface mount type) was burned when I was stupid enough to select 200uA instead of 200V of the meter. This meter is quite cheap, but very nice to work with and I was hoping to try to save it before a discarding it. But I will appreciate any help that you can provide. Thank You! Ron.	ronald_herrera (17351)
1397011	2015-03-23 13:48:00	I have done a long search for your circuit diagram in my usual sources and others but sorry mate no luck. Do you have any literature pointing to the manufacturer's support location to try? They may be good enough to send you a copy by email but I doubt it. This route has worked for me a few times in the past. Just as well that is a comparatively cheap multimeter.	blanco (11336)
1397012	2015-03-23 21:08:00	Unfortunately , given its a $15 meter (incl shipping from china), there is zero chance of there being published circuits for it www.tmart.com It amazes me just how cheap this sort of stuff is from china. Just how could they possibly make it for that sort of $	1101 (13337)

Just how could they possibly make it for that sort of $ They sell for less than US$10, so by the time he has found the component value, bought some SM resistors (minimum order probably 10) and the necessary tools to make the change, Ronald could buy a new and much better meter that has effective overload protection. Mind you, I can't talk! :blush: I recently spent a few hours stripping down and repairing a 'cheap as chips' digital clock with 2 timers. I had dropped it in water, but I already had a second example that was still working OK so it was no great loss. Basically I was doing penance for being careless enough to drop it in the first place. Not been a good time for me recently, I also dropped my camera in a puddle and it spat the dummy. Fixed that too, but it was touch and go for a while. Memo to Self: Don't carry timers, cameras, phones or any other small electronic items in your shirt pocket! :groan: Cheers Billy 8-{)	Billy T (70)
1397014	2015-03-24 02:18:00	Same as my multimeter I bought from ebay for about NZ $13. Amazon lists the brand name (Extremes) and part number. (amzn.to) Searching Google from Amazon (right click) direct lists some Japanese/Chinese results here. (bit.ly) You could try Google Image search for circuit diagrams/schematics, and may find at least generic diagrams. Or maybe search Google Patents. (bit.ly) But unsure if a patent would have been produced from China.	kahawai chaser (3545)
1397015	2015-03-24 03:49:00	Buy a new one, open it up & get the value direct from the new meter. You may need to buy a 3rd meter in order to measure the value of said SMD off the 2nd one. But anyway, good on you for at least trying to fix it.	1101 (13337)
1397016	2015-03-24 20:50:00	Well, I have some SM (surface mount resistors) in some boards. But I'll need to replace the very same one (for accuracy readings) and, as some of you guys noticed, it's very difficult to find a schematic or at least someone that have the same meter and telling me the value of R5 at least. Thank you to all of you for your comments & reviews. I'll be in touch if something comes up or someone have an answer. Thanks!	ronald_herrera (17351)

1397018	2015-03-24 21:14:00	Of course there may be other damaged or burnt out components , so you may end up having to replace quite a few components & do some extensive fault finding .	1101 (13337)
1397019	2015-03-24 21:34:00	That's right, 1101. There's a chance that other components are damaged by the discharged. Since I have another (different) multimeter, fixing the xl830l is just a practice to puzzle-repairing the cheap meter. It is that I couldn't find anywhere the value of the resistor at hand. But, hey!, thank you for spending your thoughts with me. I appreciate it. :-)	ronald_herrera (17351)
