The use of signal generator requires attention and method
Use an electroscope generator with the same voltage grade as the electroscope. Hold the working part of the electroscope (the electroscope head) and touch the electrode head of the generator with the electrode head of the tested electric appliance and press the "work" switch. At this time, the acousto-optic signal of the electroscope indicates that the performance of the electroscope is intact. If the silent light indication indicates that the electroscope is faulty, it should be repaired or replaced. When detecting the proximity alarm helmet, just press the "work" switch with the electrode head of the high-voltage signal generator close to the alarm.
1. The signal generator is equipped with "power indicator". The indicator light does not light up when using, and the battery should be replaced before use.
2. Signal generator should be placed in dry and ventilated place when not in use to avoid damp.
