This is what I got RadioShack 17-Range Analog Multimeter : Multimeters | RadioShack.com. Based on the reviews it's a pretty bad multimeter. I used it to test my 18650s and it was fine. The difficult part is for sub-ohm readings. I set the meter to 10x ohms setting and test the internal resistance by touching the leads together and the needle came to 9 which would translate to 90 ohms since the manual said that you need to multiply the number by a factor of 10 to get resistance. Now that's just weird. I then put the leads on my igo-w and the needle went to 9 again. So that's weird. I know my build is 0.5 ohms because I used a friend's multimeter a week ago. Does anybody have any experience with this multimeter?
