How To Use A Lap Multimeter Uk
The item being repaired should be turned off and the multimeter set to resistance which may be symbolized by a horseshoe shaped icon.
How to use a lap multimeter uk. The multimeter acts as if it was a wire in your circuit. 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. If you disconnect the multimeter your circuit won t work. 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.
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. 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. 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. How to use a multimeter.
This won t hurt the multimeter but we need to set the dial to a higher range. Multimeters are used in all areas of electronics to determine the voltage amperage or resistance in an electrical circuit. For this function the probes are interchangeable. For starters lets go over some of the different parts of a multimeter. 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.
Screwfix tests ac dc voltage dc current and resistance. If you set the range too low the multimeter simply reads 1 or ol indicating that it is overloaded or out of range. They are available in two varieties analog and digital. 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.
