Research shows that each year hundreds of people killed each year in accidents that occur because of power outages and fires from short circuits. They occur mainly due to the ignorance of people who are not available skills and correcting errors, and also because a lot of hesitation on their part to help themselves from the point of comment is a true professional important problem. Some practical tools for electrical test should remain at home in case of emergency. Although it is desirable that you get professional help immediately, the fastest, these tools can be useful, at least those that are more or less a fair idea of the electrical test.
Analog ammeters: they are used to measure the current flow. The current level is displayed on a dial, amps, using a pointer. It is useful to determine the right amount of power needed to run all electric good.

Analog Multimeter: As its name suggests, it is necessary to measure important aspects related to the flow of current, voltage and the signal strength and accurate reading in a short period of time.
analog voltmeter: They are used to determine the voltage across the circuit and also inform the user when a voltage drop. The mechanism is simple, with a simple needle shows the current voltage reading of the tone.
Trace the circuit: It is also known as the trace of the signal, which is probably the most important test of the devices, which helps to find the fault on the circuit first. They help to identify common problems such as short circuits and breaks.
Stack: device is very useful, electricians, because users can measure current in a circuit, nothing from principal son. With all the readings and the aid needed to identify the mechanism is under a heavy load.
