The commonly occurring electrical faults may appear intractable for someone who is not an expert at handling such tasks. Regular inspections of the safety framework are often avoided and the electrical assignments are left pending.
A digital multimeter is a vital component in the safety structure of your home. It is a testing device that observes the circuit state of a particular device or the electric outlet.
A digital multimeter makes the inspection easy with its simple to read digital readings and LED indicators to notify you about the progress of the undergoing test.
If you notice an electrical device, appliance or a socket not operating in a normal way then its time to take the services of your multimeter. There are three types of tests that can be preformed to know whether the circuit is short, open or close. That in turn would help you in further course of action.
Keep certain excerpts in mind while purchasing a new digital multimeter. It should not fall below the impedance limit of at least 10 mega ohms. If your multimeter has more resistance then current draw will be more leading to a breakdown in the circuit of the under test appliance.
To diagnose a problem associated with an appliance/socket, clutch the two ends of the testing lead to the device's cable taking care that the red wire is clutched to the positive terminal and black one to the negative terminal. There are three types of test that one can do. The first one is the amperage test. The ampere(A) is selected on the multimeter first and the multimeter wire is attached to the appliance/socket. The resulting reading( in amperes or milliamperes) shows the current passing through the component being tested.
Second one is the voltage test which tests the potential difference between the two terminals of the outlet. This time around the multimeter is set to V indicator.
An ohms test will tell you if circuit being tested is an open one or a closed one. If reading reads 1.000 or 'OL' then it means resistance is infinite and the circuit is open. If the reading is 0 then it means no resistance from the circuit and hence it is shorted. If however the resistance reads a bit more than the inscribed ohm limit of the outlet/device then it also indicates a short in the circuit.
