How To Use A Lap Multimeter Uk

If you set the range too low the multimeter simply reads 1 or ol indicating that it is overloaded or out of range.

How to use a lap multimeter uk. How to use a multimeter. A multimeter is an instrument used to check for ac or dc voltages resistance and continuity of electrical components and small amounts of current in circuits. 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. For this function the probes are interchangeable. If you disconnect the multimeter your circuit won t work.

Analog versions are cheaper to buy and are fine for establishing a current but if you need a level of accuracy a digital version is much. Use the probes to measure resistance by placing one on each side of the component to be measured. Screwfix tests ac dc voltage dc current and resistance. A multimeter is a versatile tool that can be used to measure electrical resistance within a circuit just as you would use a ruler to measure distance. They are available in two varieties analog and digital.

At the very basic level you have the device itself along with two probes which are the black and red cables that have plugs on one end and metal tips on the other. If you ve got a faulty appliance within your home and you re not sure what s causing the fault a great way to find out is to use a multimeter. This won t hurt the multimeter but we need to set the dial to a higher range. So you need to connect your multimeter in series with your circuit. The other possibility is that the circuit or component you are testing doesn t have continuity that is it has infinite resistance.

To place the multimeter in series you need to place the red probe on the lead of a component and the black probe on the next component lead. The item being repaired should be turned off and the multimeter set to resistance which may be symbolized by a horseshoe shaped icon. This instrument will let you check to see if there is. For starters lets go over some of the different parts of a multimeter.
