How To Use A Multimeter Sparkfun Learn 1. turn the dial on the multimeter to read a dc voltage. look for 20v and turn the knob to select. if you used this setting to try and measure a 40v project the multimeter would run out of range. 1. set the multimeter to ohms or resistance. turn the meter on if it has a separate power switch. when multimeter measures resistance in ohms, it can not measure continuity because resistance and continuity are opposites. when there is little resistance, there will be a great deal of continuity, and vice versa.
How To Use A Multimeter To Measure Voltage Current And Resistance Amps, volts, and ohms: this video is for beginners to learn the basics of how to use a digital multimeter to test voltage, current and resistance using the k. In this video i go through the basic functions of a cheap multimeter, i cover how to measure ac and dc voltage, how to measure resistance, how to test for co. Pick out a random resistor and set the multimeter to the 20kΩ setting. then hold the probes against the resistor legs with the same amount of pressure you when pressing a key on a keyboard. the meter will read one of three things, 0.00, 1, or the actual resistor value. Following this, plug the black lead into the ground (com) terminal. adjust the dial to the a or milliamp setting. 4. determine the current type: ac or dc. once the multimeter is on, set it to either ac or dc based on your source. for some fluke models, the yellow ‘function’ button toggles between ac and dc.

To test batteries: switch the multimeter to dc voltage (a “v” with a straight and dashed line above or next to it) and in the proper range. some multimeters, like ours, also have a battery test function. attach the black probe to the negative side of the battery. attach the red probe to the positive side of the battery. Connect the test leads to the circuit you wish to test. connect the black probe first. touch it to the negative terminal if you’re testing a device with one. then, touch the tip of the red probe to the opposite terminal or end of the circuit. the multimeter’s display will change as the current flows through it.
