advantages of having an analogue multimeter for component testing?
-
fixed so far...376 lg lcd tv's,24 onn tv;s,24 panasonic lcd,16 jvc lcd,12 marshall jcm800 amps,refurb of various disco equipment lighting,old style disco decks ,and a flymo!
----------------------------------------------
please let us know if everything works ok if your tv gets fixed, as it will be and aid for anyone else having the same problem and wishing to fix it.it would save people clogging up this site with topics that are duplicated,and can be found easily using the search function.,and taking up valuable space.enjoy your fixed tv!,hopefully! -
Re: dmm v analogue
Get a digital multimeter that has an analog bar graph to get the best of both worlds. For example, a Fluke 117 updates the digital display 4 times per second and its bar graph updates at 32 times per second. So if you have wild fluctations in voltage you will see it on the bar graph quite easily.
Other brands also have the same bar graph feature.
Having said that, from what I understand the UK loves the old analog AVO multimeters. There is a forum dedicated to vintage test gear (over 17,000 posts) at
http://www.vintage-radio.net/forum/f...splay.php?f=36
If you can get an AVO for really cheap, then I suggest you get one. In the USA, Simpson is the highly regarded analog multimeter.--- begin sig file ---
If you are new to this forum, we can help a lot more if you please post clear focused pictures (max resolution 2000x2000 and 2MB) of your boards using the manage attachments button so they are hosted here. Information and picture clarity compositions should look like this post.
We respectfully ask that you make some time and effort to read some of the guides available for basic troubleshooting. After you have read through them, then ask clarification questions or report your findings.

Re: dmm v analogue
Being able to see the rate of change of what you're measuring is what analog is good for."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Re: dmm v analogue
For speed, analog is the best, and for accuracy, digital is best.My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.Comment

Re: dmm v analogue
The analog is good for fast changing voltages or mA.
The dirt cheep digital are slow as turtles.
The 300-400$ modern digital ones does have the speed to measure almost anything.
Even so by having at hand plus one high quality analog, you are 100% ready to measure anything.Last edited by Kiriakos GR; 05-23-2012, 02:26 PM.Comment

Hi guys I asked a friend of mine to give me the resistance measurements on a 3V Rail on a Macbook Pro 2017. He doesn't have any digital multimeter at the moment. Do any of you have experience with this analog multimeter and can be able to tell me what is the reading in ohms being displayed ? Just need to know if this line is shorted.Thanks... -
I read EBOOK of Testing Electronic Component and found that
"In order to test the small blue resin coated ceramic disk capacitor which has 104 50v specification,it is possible to test this small ceramic capacitor by making use of analogue meter.
Set to times 10Kohm that has 12v output from the probe to check disorder of ceramic capacitor.
It is not uncommon that testing result of digital capacitance meter is okay,But It show shorted reading when you check it with analogue meter."
Is it really possible to test small ceramic disc capacitor with analogue... -
I am new to electronics and I'm understanding most of what I'm reading but I have a mosfet on my board that I've identified as a P-channel Trench Mosfet. I haven't a clue how to test this and what I should expect to see with the multimeter probes. I am hoping someone with years more experience than myself can help me understand how to use a multimeter to read this. Please look at the drawing I have attached to this and can you try to explain to me what I should be doing with my multimeter in diode mode and what results I should expect from a good mosfet?...

Hi Guys,
Weird one here. I have a special GPU made by DFI (Model LS3440) from an Arcade gaming machine. The GPU uses the S3 440 GTX Chipset, and has dual DVI-I ports. For some reason, the analogue has stopped working on both outputs (DVI-I to VGA cable). DVI-D and digital outputs work fine, just the analogue that has stopped working.
Now, I could get around this by using Active cables to convert the signal over to Digital, but its got me wondering exactly what the issue could be. I have inspected the GPU and DVI ports under my microscope, but nothing stands out. Because... -
Most analog meters are actually current driven - a current is needed to deflect the pointer full scale. They can be lots of different values. There are ones that can take several amperes to swing the pointer as they have internal shunts.
On the other hand there are many that are rated in microamps for the intent that they draw as little power as possible from the devices under test. Some are 1mA, 500µA, 200µA, 100µA, and the ubiquitous 50µA frequently used in analog VOMs. There are even 20, 25, 30 µA and even down to 10µA. Been collecting a bunch of different ratings and...
