You can test a capacitor using a multimeter and two leads by placing the multimeter in ohms mode. It works best with a needle type meter, not a digital meter. Connect the leads to the capacitor and you will notice that the resistance pulses down, and then settles out at infinity. Reverse the leads, and you will notice the same effect, except that the pulse will be larger because the capacitor got charged in the opposite direction. Go back and forth. This won't be apparent for very small capacitors because the pulse is too short. Also, for electrolytic capacitors, they should only be charged in one direction, so you should start by discharging the capacitor and then connecting it in only one direction. Do not reverse the leads in this case. Just discharge and try again to see the effect. Try this for various capacitors. You will notice that the pulse duration is larger for larger capacitance.
by noticing the polarity of theohmmeter a diode can be checked for continuity and blocking ability However it will not tell you how good or bad the device itself is BY keeping the multimeter in diode mode and keeping properly the positive and negative terminals of the multimeter. If the diode is good multimeter will show a reading of 0.5 else there will be a short.
Multimeter test leads can be purchased at specialty stores like Radio Shack or some larger hardware stores. They can also be found online at Amazon and eBay.

To test a light switch using a multimeter, set the multimeter to the resistance or continuity setting. Disconnect the switch from the power source and remove it from the wall. Place one multimeter probe on each terminal of the switch. If the multimeter shows a reading of zero or close to zero, the switch is working properly. If there is no reading, the switch may be faulty and needs to be replaced.
The accuracy is the biggest advantage.
To test if a coax cable is live using a multimeter, set the multimeter to the continuity or resistance mode. Touch one probe to the center conductor of the coax cable and the other probe to the outer shield. If the multimeter shows a reading, the coax cable is live.
You can use a multimeter. If you need instructions on using one, I am sorry.
To test a light bulb using a multimeter, set the multimeter to the resistance or continuity setting. Touch one probe to the base of the bulb and the other probe to the metal threads at the bottom of the bulb. If the multimeter shows a reading, the bulb is functioning. If there is no reading, the bulb may be faulty and needs to be replaced.
Resistors have tolerance. So does the multimeter. Standard resistors range from 20% (no fourth band), to 10% (fourth band silver), to 5% (fourth band gold). Resistors will not normally measure exactly what you expect, and proper circuit design must take this into account.The multimeter may not be calibrated correctly.
To test a light switch using a multimeter, set the multimeter to the resistance or continuity setting. Turn off the power to the switch, remove the switch cover, and disconnect the wires. Touch one multimeter probe to each terminal on the switch. If the multimeter shows continuity or a low resistance reading, the switch is working properly. If there is no continuity or a high resistance reading, the switch may be faulty and needs to be replaced.
A multimeter, also called a VOM, is an ohmmeter, ammeter, and voltmeter combined in one case. A function knob can be turned to select the type of measurement to be made, such as volts, amps, or ohms. The multimeter's test lead connections to the circuit will depend on whether you are using it as a voltmeter, an ammeter, or an ohmmeter.
step one. put down multimeter. step two. google the JFETS serial number step three. click the link that looks like a datasheet. step four. find the pin configuration. Probably alot easier than finding which two have low resistance when you apply voltage to the gate (assuming N type)
Use a multimeter set to continuity position and touch one probe from your multimeter to each conductor. If you hear a tone from the multimeter then your fuse is good.
You can run a circuit board test by using a multimeter with the ohmmeter setting. Turn the multimeter to the lowest setting and touch one lead to the tester at the solder point and the other to the socket. The resistance should read 0. A reading of infinity signifies a bad connection and will need to be re-soldered.
