How To Use A Lap Multimeter Uk

The multimeter acts as if it was a wire in your circuit.

How to use a lap multimeter uk. 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. They are available in two varieties analog and digital. 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. If you disconnect the multimeter your circuit won t work.

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. For starters lets go over some of the different parts of a multimeter. The item being repaired should be turned off and the multimeter set to resistance which may be symbolized by a horseshoe shaped icon. 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. 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.

So you need to connect your multimeter in series with your circuit. 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. For this function the probes are interchangeable. Multimeters are used in all areas of electronics to determine the voltage amperage or resistance in an electrical circuit. The other possibility is that the circuit or component you are testing doesn t have continuity that is it has infinite resistance.

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 multimeter. Screwfix tests ac dc voltage dc current and resistance. This instrument will let you check to see if there is.
