Johny B Posted November 3, 2011 Report Share Posted November 3, 2011 Hey guys so i found this at Walmart the other day for $12.00. http://www.walmart.com/ip/Equus-3300-Hands-free-Digital-Multimeter/14644665 My question is you think it works? i was expecting them to be like 120bucks. I want to use it to check my battery voltage, ohm load and to tune my amps so that im not clipping my sub. Anybody have any experience with it?? thanks Quote 06 Chrysler 300 Pioneer avh-x8500bhs Hertz Hsk 130.4 Alpine mrp-F600 2 Dc level 4 12s Dc 2k Viper 5901 SHCA wiring KnuKonceptz RCA's SecondSkin/Fatmat Big 3-stock alt Link to comment Share on other sites More sharing options...
Guest Posted November 3, 2011 Report Share Posted November 3, 2011 itll work fine. the multimeter i've been using for years costs $1.50 online last time i checked. only thing to watch out for is when measuring the resistance of a speaker, touch the dmm leads to each other and see what number comes up on the meter. if its anything but 0, you will have to subtract that number from the number you get when you measure the woofers. example, multimeter reads .5 ohms when touching together. sub reads 1.5 ohms. subtract .5 because of the multimeters internal resistance. sub actually is 1 ohm.

That helps out ALOT thanks! i might go buy it later on but ill see if i can find a even cheaper one now lol Quote 06 Chrysler 300 Pioneer avh-x8500bhs Hertz Hsk 130.4 Alpine mrp-F600 2 Dc level 4 12s Dc 2k Viper 5901 SHCA wiring KnuKonceptz RCA's SecondSkin/Fatmat Big 3-stock alt Link to comment Share on other sites More sharing options...
SnowDrifter Posted November 4, 2011 Report Share Posted November 4, 2011 It should work fine for everything except making sure you are not clipping your subs. You need a different tool to do that (oscilloscope / DD-1) Quote ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...

Mario928 Posted November 4, 2011 Report Share Posted November 4, 2011 I have the same one i also bought it in Walmart for the same price. It is pretty good for the price all i use it for is for measuring voltage.

BassMunky Posted November 4, 2011 Report Share Posted November 4, 2011 why did he say subtract when on the bcae1 site he adds volts to it and rounds up?

Guest Posted November 4, 2011 Report Share Posted November 4, 2011 why did he say subtract when on the bcae1 site he adds volts to it and rounds up? what volts? its resistance. when you put the two leads together, the meter will show what its internal resistance is. when you measure the sub, why would you want to take into account the meters internal resistance along with the voice coil resistance? you obviously just want the voice coil reading, so you subtract the two numbers.
