This page is about helping you use the multimeters at ITP (that's the main kind we have
here in the shop pictured on the left).
It shows how to set up the Multimeter and what to do with your
circuit if you want to measure Resistance, Voltage, or Amperage.
In the table below, the image on the left shows how to configure your multi-meter. These are images of the main kind of multimeter at ITP, though it should be helpful for any multimeter. The Image on the right shows how to use the multimeter in your circuit so that you are sure you are actually measuring what you think you are!
A more detailed look at the entire face of the multimeter shown on the left can be seen here.
Another very useful tutorial is an internet video from Make Magazine that shows how to use a multimeter. This video is here on Youtube. Thanks to Tom Igoe for the link.
A quick and very important note on measuring Amperage. Make sure that you first measure using the 10A setting. If you see that the Amperage you are pulling is lower than 200mA, use the more sensitive setting.
