Signal generator is a device that provides a variety of frequencies, waveforms, and electrical signals of output levels. It is widely used in the field of production practice and science and technology.
The signal generator with the same voltage grade electroscope. The work will be part of the electrode head with electroscope electrode head contact by electrical generator test, press the "working" switch, a sound signal that the electroscope electroscope performance intact. As a silent light indicating electroscope is faulty, should be repaired or replaced after use.
The signal generator is provided with "power indication". When the indicator light is not used, the battery should be replaced before use. The signal generator should be placed in the dry and ventilated place when not in use so as not to be affected by moisture.
