I have here a Radioshack multimeter, and I want to check the resistance in Ohms of a resistor I have here. These are the settings on the multimeter: 1000 AC V 250 AC V 50 AC V 250m DC A 50µ(250mV) DC A 5 DC V 25 DC V 125 DC V 500 & 1k DC V RX 1 Ohms RX 10 Ohms RX 1K Ohms Which setting do I use to find the resistance, and how will I read it? Thanks
You'll use one of the RX settings, which one depends on how high the resistance it is. To read it, simply put one probe on each side of the resistor. Start off w/ the 10 ohm setting, as most likely the resistance will be withing 10-999ohms (if it's higher, then you'll probably have a reading of 000 with a flashing 1 at the beginning, indicating it's out of range).
Ok, I put it at the 10 Ohms setting, and the pointer was at "10" when I touched the probes to the leads on the resistor... so it's a 10 Ohm resistor?
Not likely. It probably means that the resistance is out of range. Put it to 1k and retest. I did screw up on my last post, as the settings sounded like they went FROM the specified number to the next one, not up TO the specified number.
It had about a half Ohm when I set it to the 1k setting. Hm... I need to convert from 5 volts to 3 volts, know how I can?
You read the scale wrong there should be a 0-1 ohm reading scale, and a 0-10 ohm scale, for the 1k ohm read the 0-10 and multiply by 100.
