Voltage tester is a low-cost type of test lamp only contacts one side of the circuit under test, and relies on stray capacitance and current passing through the user's body to complete the circuit. The device may have the form of a screwdriver. The tip of the tester is touched to the conductor being tested (for instance, it can be used on a wire in a switch, or inserted into a hole of an electric socket,car). A neon lamp takes very little current to light, and thus can use the user's body capacitance to earth ground to complete the circuit.
The multimeter is one of the most basic skills in electronics. It is a good assistant to test and troubleshoot faults that exist in electronic device. This Digital LCD Multimeter Voltmeter Ohmmeter Ammeter will meet your demands. Adopting durable material, it is tough enough to be used for a long time. Besides, it can be used in measuring remaining capacity of the rechargeable battery, so as to check whether the battery is fully-charged.
