Detector USB, tester of voltage of current, voltmeter ammetre Portable for charger of phone Portable, 2 pieces, white

Features:

1. The tester USB can measure the voltage when equipment power supply USB is to empty, as well as the voltage and the current when equipment terminal USB works.

2. With display of the cycle of current and of voltage, the tester USB is easy to use and practical, which can be small and easy to carry, not need power supply additional.

3. This tester energy electric uses a new generation of circuits previennent of conversion cyclique semi-integrale 4 1/2, equipped a source of reference of strip interdite precise, which takes in load a range precise, a high precision, a stable operation, performance reliable, a strong capacity anti-interference and resistance to high temperature.

4. And this detector USB can be used for measure power supply or the consumption energy of products such as the interface USB, the charger of phone portable, the disc U, etc.

5. in addition, a such detector USB can detect the quantity of current that the phone mobile load. It can also detect that the performance of the line of load of the phone portable are mediocres. for example, a line of load to low resistance internal can obtain the current of load specifie of the phone mobile. If a cable of load to high impedance is used, the current of load increase not. Thus, the bad performance is creusee.

6. Measured easily the voltage of output of the port USB and the current of work of equipment, the detector of size compact is without power supply and other equipment auxiliary, plug and play.

7. During this time, the tester USB can also detect if the voltage and the current of output of the charger USB are ieee to the standard, suitable to the machined, to the laboratory and to the users.
