It is forbidden to be used as a voltage detector._x000D_Due to the high pressure operation is very dangerous, operators must undergo strict training and obtain corresponding high pressure operation certification before using the instrument for field testing._x000D_2: When using, please wear the alarm on the wrist exposed skin, and make the case close to the skin.Make the triangular symbols on the surface of the alarm point pointing in the direction of the fingertip._x000D_3: This alarm only provides safety auxiliary measures. Please do not overestimate the safety guarantee after wearing this alarm._x000D_4: The working distance of the alarm will be greatly reduced when it is close to the ground metal structure (such as transformer)._x000D_5: If the alarm is hung on the sleeve of the overalls or rubber gloves, the sensitivity will be greatly reduced._x000D_6: When the alarm clock is wet by rain, please take out the battery and dry naturally in the shade.Please do not use the alarm in the damp state, this time will greatly shorten the working distance of the alarm, and even the alarm will always send out an alarm._x000D_7: If the alarm is struck or struck by a strong external force, check the appearance of the alarm and press the "TEST" key to make sure that the alarm function is working normally._x000D_8: Please read the instruction carefully before operation. 1Wrist watch type high voltage alarm provides a safe, practical and convenient new high voltage alarm for the close operator. 2After the operator wears this alarm, when it is close to the high?voltage charging body for a certain distance, according to the safety distance of the corresponding voltage level, the alarm will send sound and light alarm, reminding the electrician to pay attention to safety and avoid high?voltage electric shock accidents. 3The high?voltage alarm adopts non?contact induction technology, accurate alarm, power saving and durable, standby time up to 12 months. 4The alarm has a unique automatic trigger detection function, which can ensures the safety of the workers near the electricity. 5Alarms are widely used in electric power, railway, industrial and mining enterprises and other closed electric power operations. 1 x High Voltage Detector 1 x Manual
