Feature:1. It provides operators with a safe, practical and convenient highvoltage alarm.2. Using noncontact sensing technology, accurate alarm, power saving and durable. The standby time is up to 12 months.3. The unique automatic trigger detection function can ensure the safety of workers near the power.4. Highvoltage alarms are widely used in closed power operations such as electric power, railways, industrial and mining enterprises.5. After the operator wears the alarm, when the highvoltage realtime body is close to a certain distance, the alarm will sound and expose.Specification:Item Type: High Voltage DetectorMaterial: ABSAlarm voltage and distanceModel Voltage gradeAlarm distanceETCR18601KV0.1m6.6KV0.6m10KV0.8m35KV 1.3m66KV1.8m110kV2.2m220KV3.0m330KV3.6m500KV 4.2mTechnical ParametersWorking power supply 1XCR1632 button battery (not included)Meter voltage range ETCR1860: 1KV-500KVTable distance error10cm (231, 80%RH under basic conditions)Working frequency 50/60HZElectric test mode Non-contact modeDetection mode Automatic triggerBattery life Continuous work (acousto-optic alarm): about 24 hoursStandby time: about 12 monthsAlarm modeIndicator light: LED visibility under 8000LX visible light Buzzer: above 60dB (distance 60CM)Protection grade IP54Working environment -10-40; less than 80%RHStorage environment -10-60; less than 70%RH.How to use:1. The wrist alarm is not a voltage detector, and it is prohibited to be used as a voltage detector. Because high-voltage operation is very dangerous, operators must undergo rigorous training and obtain corresponding high-voltage operation certifications before using the instrument for on-site testing.2. When using, please wear the alarm on the bare skin of your wrist and keep the watch case close to the skin. Make the triangular symbol on the surface of the alarm point point toward your fingertips.3. This alarm only provides safety assistance measures, please do not overestimate the safety guarantee after wearing this alarm.4. Near grounded metal structures (such as transformer), the working distance of the alarm will not decrease.5. If the alarm is hung on the sleeve of work clothes or rubber gloves, the sensitivity will not decrease.6. When the alarm clock gets wet in the rain, please take out the battery and dry it naturally in a cool place. Please do not use the alarm in a humid state, this time it will greatly shorten the working distance of the alarm, even the alarm will always sound an alarm.7. If the siren is hit or hit by a strong external force, check the appearance of the siren and press the "TEST" key to test to ensure that the siren functions normally.8. Please read the manual carefully after purchase.Package List:1 x High Voltage Detector (Battery Not Included)1 x Manual1 x Button Piece
