First, the overview: The electroscope is the power system and industrial and mining enterprises operating electricity necessary security tools, it is used to detect 0.1kV-500kV lines or equipment is running with the power frequency voltage to ensure that the staff in the maintenance of power outage Personal safety. The production of GDY-II-type sound and light electroscope, is divided into 0.1kV to 500kV seven voltage level products for the user to choose the order according to the actual operating voltage level. When it is audible, it sends out sound and light double alarm signal to prompt the staff to be seized line or equipment charged. The electroscope in the electric power industry electrical safety equipment testing center through the type test, the main technical indicators in line with DL740-2000 power industry standards and international IEC technical standards. Products through the provincial-level appraisal and review by the power industry.

Second, the use and precautions:

(A), before use, according to the rated voltage of electrical equipment to choose the appropriate voltage level qualified electroscope.

(B), electroscope must be self-test before use: the method is to press the self-test button with your finger, the indicator light intermittent flash, and issued an intermittent alarm sound, indicating the instrument is normal.

(C), for more than 10kV inspection work, must be "electrical safety work order" implementation, the staff wearing insulated gloves, wear insulated boots, and to ensure safe distance of live equipment.

(D), inspection, the staff holding the grip below the electrical part of the ring, and in accordance with the "Electrical Safety Working Rules" requirement, the first electrical facilities on the test, verify the electroscope does the performance intact, Can be used, the rainy day fog days shall not use the instrument.

3, regular experiments: In order to protect the safety of people and equipment, according to "electrical safety work order" provides that the electroscope should be insulation for regular pressure experiments, start the experiment, wet place for three months, dry place six months, Direct, should stop using.

Fourth, carry and keep:

1) Avoid dropping, squeezing, strong shock, vibration, do not use corrosive chemical solvents and cleaning solution scrub.

2) Do not exposure to open sun exposure, often kept clean, dry place.

3) The electroscope (indicator) uses the SR44 button and battery (1.5 volts) 4, when the self-test switch (such as the indicator is weak) (including abnormal) should be replaced
