Bodyshots Posted March 4, 2015 Share Posted March 4, 2015 I have a common resistor that should be easy to identify, unfortunately because of the way I see colour, especially golds,browns,beige and shadings makes it really hard for me to identify them. Even using reference online I'm unfortunately unsure of myself. It's no problem when I know what I need by calculations and then it's simple to order. Perhaps someone might take a minute to shoot me the #'s please. To me, the first 2 numbers and the tolerance look closely the same (embarrassed) Quote Link to comment Share on other sites More sharing options...

Bodyshots Posted March 4, 2015 Author Share Posted March 4, 2015 Thanks, Im shaking my head frustrated, because I am doubting you, yet I know you are probably right, lol…. It's frustrating not being able to tell the colours properly. There was a time in my teens when I could drive at night and positively identify who was driving the car in the opposite oncoming traffic lane… Quote Link to comment Share on other sites More sharing options...
Osgeld Posted March 4, 2015 Share Posted March 4, 2015 looks brown black brown to me (100 ohms) use a meter 1 Quote Link to comment Share on other sites More sharing options...
7800fan Posted March 4, 2015 Share Posted March 4, 2015 looks brown-black-brown to me as well, 100 ohms. gold for tolerance, I believe 5% so the resistor should be between 95 and 105 ohms. Quote Link to comment Share on other sites More sharing options...
+Stephen Moss Posted March 5, 2015 Share Posted March 5, 2015 (edited) Looks like a 100 ohm, 5% carbon film resistor to me. I find some of the metal film resistors can be quite difficult as often the brown, red and orange can look very similar to each other.

Geotrick Posted March 5, 2015 Share Posted March 5, 2015 couldn't you just measure with a meter or does the fact that it is mounted interfer with accuracy? I happen to be looking up resistors and came appond this chart/calculator. http://www.sysrecon.com/resources/4-band-resistor-color-code-calculator/ working on a 5200 RSI.

7800fan Posted March 6, 2015 Share Posted March 6, 2015 You can't reliably measure resistor in circuit. You would need to desolder or clip one leg and life it out to break any connection before you can measure it. Quote Link to comment Share on other sites More sharing options...
Osgeld Posted March 6, 2015 Share Posted March 6, 2015 (edited) that's not always true, do it all the time and it depends on what its hooked up to, and 9 out of 10 times if you cant measure it, it will be grossly wrong Edited March 6, 2015 by Osgeld Quote Link to comment Share on other sites More sharing options...
Wickeycolumbus Posted March 6, 2015 Share Posted March 6, 2015 It could totally be 100 ohms, I'm not very good at those colors myself. A lot of times it will be in parallel with something else, which will change the measurement. Quote Link to comment Share on other sites More sharing options...
SoundGammon Posted March 6, 2015 Share Posted March 6, 2015 (edited) Here's a device that's in shipment to me now. Got it on E-Bay for $20.00 Checks: Transistors Capacitors Resistors Inductors Diodes LEDs and more! You don't even have to "hook it" up any special way! Just connect to 1, 2 or 3 using the supplied jumpers. It will tell you the pinout of the device being tested! Check the pics!

S1500 Posted March 6, 2015 Share Posted March 6, 2015 Color blind people must have lots of fun trying to read resistors. I've given up and just use a voltmeter. 1 Quote Link to comment Share on other sites More sharing options...

7800fan Posted March 6, 2015 Share Posted March 6, 2015 I got something similar, very similar to this one: eBay Auction -- Item Number: 151608720074 and works good for me. Stick an object in 2 or 3 of the holes and push button. It tested for capacitor rating and its ESR, resistors, transistors, and inductors. Most of them go for under $15 for bare board model with common 2x16 character display. I haven't seen one with graphic display as shown above 1 Quote Link to comment Share on other sites More sharing options...
Geotrick Posted March 7, 2015 Share Posted March 7, 2015 This is supposed to be 500K but measures .500M, This will sound like a stupid question but, these two numbers are different, correct? Quote Link to comment Share on other sites More sharing options...
7800fan Posted March 7, 2015 Share Posted March 7, 2015 500k is .5 M. K for kilo, M for mega. Mega = 1000 kilo. Quote Link to comment Share on other sites More sharing options...
Geotrick Posted March 7, 2015 Share Posted March 7, 2015 Ok I was expecting the meter to show 500K. I tried measuring 2, of the 250Ks in series and It came up .500M Quote Link to comment Share on other sites More sharing options...

Osgeld Posted March 7, 2015 Share Posted March 7, 2015 9 volts do suck cause they have squat current capacity and they seem like they are made out of solid gold for the price they want for them, my meter uses one and i replace it least once a quarter. and thats just for a meter that is only on a few second a week!

SoundGammon Posted March 7, 2015 Share Posted March 7, 2015 (edited) Do you have a link? Here's one: http://www.ebay.com/itm/2015-newest-version-of-inductor-capacitor-ESR-meter-DIY-MG328-multifunction-test-/321618200447?pt=LH_DefaultDomain_0&hash=item4ae1f0477f This is in the description: Short three test side, into the test, the screen prompts correction step. When prompted to disconnect the short end of the calibration time off three tests will continue, when prompted in the 1-3 foot access 100nF capacitor over time, access to distribution after correction capacitors 1uF program will automatically enter the next step. Correction until the end of the restart to complete the correction. Can anyone make any English out of it? lol Edited March 7, 2015 by SoundGammon Quote Link to comment Share on other sites More sharing options...

The display of the text on the site keeps going past the margin also. It looks like it is supposed to be the manual. What is the connector just above the red led? It looks like a USB port from the top view. Quote Link to comment Share on other sites More sharing options...
7800fan Posted March 8, 2015 Share Posted March 8, 2015 I don't like 9v bats, I will keep looking. I got an old universal AC adapter from 80's that has 4 tips and 9v plug. From when many of the early LED handhelds used 9v battery. That works for the meter I have, never have a run down battery. It's dang near impossible to find an universal AC adapter today with 9v plug. 1 Quote Link to comment Share on other sites More sharing options...
Geotrick Posted March 8, 2015 Share Posted March 8, 2015 in the end I placed a bid on one that takes a 9v. I have a dc 9v brick I will put an inline switch on. Quote Link to comment Share on other sites More sharing options...
