Second, product characteristics:
1Electric shock pre- alarm (Near electric alarm) .High-pressure pre- alarm function with electric shock , low power features with experience . Near electrical alarm circuit design our own dedicated near the fourth generation of electrical alarm circuit . The strong anti-interference performance , long life , easy to damage the circuit .
2 , the alarm system 24 hours .The alarm status is monitored 24 hours , once the wearer unconsciously strayed live in the area , the alarm immediately sound alarm issued to remind staff to wear attention to the existence of hazardous live parts to play to prevent mistakes as delusions and injuries caused by electric shock Accident.
3, alarm for a wide range of voltage .As long as the wearing of an alarm can be from 10KV-500KV can alarm and alarm distance are met DL408-91 " electrical safety rules "in respect of the provisions of the safe distance requirements can also be used for non- shielded cable and low voltage cable fault Junction detection.
4, water , earthquake resistance.Each watch near- electric alarm watch in the factory have been waterproof detector test , to ensure that electrical workers are working in the field under harsh environment can normally when the alarm warning .
5, low-voltage power function with experience .It can be exposed to lead in non- cases, to detect the firing line over AC 220V have charged . Or broken wires for cable and low voltage detection contacts . Or to check theft of power users to the wire walls .
6 watches for accuracy, small size, easy to wear .Part of the alarm time using imported movement , timing accuracy, maintenance of small . Small size , attractive appearance, easy to wear .
Third , use and wear :
1 , must be carried out before use low-voltage AC 220V electrical inspection test to ensure that the alarm is in normal working condition. ( AC 220V alarm FireWire surface distance is about 1cm-3cm alarm sound alarm to note that the alarm is in working condition ) .
2 , the right to wear watches, near- electric alarm means : The near- electric alarm watch worn directly on the left wrist or right wrist ( case required direct contact with human skin ), so watch for the body's outer surface . Deduction against the surface of the watch inside the body .
3, while you work and successive sudden alarm alarm sounds , indicating this time around there is pressure on your body you live dangerous, then do not tamper with and stop work, carefully investigate the cause and eliminate risk before it can Continue to work.
4, near- electric alarm watch alarm from the factory is measured under conditions of no interference in the use of multiple charged body should pay attention to the synthesis of electric field and electric field effects on the surrounding objects . Particular transformer tables, electrical cabinet substation grounding will reduce the warning distance .
5 , prohibiting wet in the rain alarm and the alarm after the post with water use . If the alarm is water soaked or wet , dry cloth to wipe clean, alarm , especially between the case and the table should wipe clean the glass . Experience in low voltage electrical test pass before using.
