content: Quote from: hansibull on June 17, 2016, 12:35:32 pmI was thinking about that resistor network, but wasn't 100% sure...finding right one might be a little bit difficult because that one is broken and that number didnt get any results from google.

content: That will be a call to Fluke for that part. How did it get broken ?.

content: How that resistor (blue/white) get damaged like that? Some drop the opened up meter while changing the battery or fuses?Anyway, one of the great things about eevblog is that people tear down their equipment and post pictures.In this thread, you will seehttps://www.eevblog.com/forum/testgear/fluke-179-teardown-photos/that there are five 2003 smd resistors while your Fluke 179 has one resistor.The value, thanks to clear focused pictures, is 200k ohm for each. They are in series which means 200k x 5 = 1M ohm.For the purposes of testing to see if the meter works, you can substitute any 1M ohm resistor in place.

content: Thank you for answers!This is great forum. I have readed it alot, but this was my first question.I dont know actually how that could be broken.. I got it from my friend and its quite new meter(with display protectfilm on). It doesn't seem to be dropped or anything. My best guess is that it was actually factorybroken. Meter works...Only Ohm and diode side doesn't. Sorry about my english

Don't put in a 1M ohm resistor yet.If your friend bought this meter new from an authorized Fluke dealer, he/she should have a warranty on it. Read conditions below and ask your friend. If yes, send it back to Fluke and see if they will fix it for free.My guess is that your friend bought this meter sometime in 2013 or 2014 if that 9V battery is still the factory original. Most 9V batteries have a 5 year expiration date.QuoteIf your friend has no warranty, then we can proceed to try and fixing the broken resistor.A few of questions regarding the ohms and diode. These tests will not void your warranty.1) Does this blue/white resistor measure 1M ohm or open?2) Put the meter into resistance mode. With no probes, what does the lcd show?3) Put the meter into resistance mode. Short the probes, what does the lcd show?4) Put the meter into resistance mode. Try to measure a 1k ohm resistor, what does the lcd show?5) Put the meter into diode mode. With no probes, what does the lcd show?6) Put the meter into diode mode. Short the probes, what does the lcd show?7) Put the meter into diode mode. Try to measure a regular diode, what does the lcd show?8] Put the meter into continuity mode. With no probes, what does the lcd show?9) Put the meter into continuity mode. Short the probes, what does the lcd show?

content: Quote from: Pioneer on June 23, 2016, 11:37:08 amRemote troubleshooting is difficult because of time zone, language, etc and I can't see what you are doing. So answering my questions precisely helps me help you. The reason for asking so many questions is to find out what is working and what is not and to help narrow down what exactly is wrong. Thus, skipping questions or guessing doesn't help either.My tests are simple to do and only takes 5 minutes or less to complete."Does nothing" doesn't tell me what is on the screen. A multimeter always gives a reading. It should show 0L when there are no probes attached in ohms mode.So with your replacement 1M ohm resistor in place, please answer the questions 1-9 again. If it helps you, take photos of each test and post the results here if you can't describe them in text.
