Specification: Condition: 100% Brand New Item Type: High Voltage Alarm Material: ABS Color: As shown in the picture Alarm voltage and distance Model Voltage level Alarm distance ETCR1860B 1KV 0.1m 6KV 0.6m 11KV 0.8m 33KV 1.3m 66KV 1.8m 132KV 2.3m Technical Parameters Working power supply 1xCR1632 (140mAH) button battery(not included) Alarm voltage range ETCR1860B:1KV-132KV Alarm distance error ±10cm(23℃±1℃, 80%RH under basic conditions) Working frequency 50/60HZ Electrical test mode Non-contact mode Detection mode Automatic trigger Battery life Continuous operation (sound and light alarm): about 24 hours Standby time: about 12 months Alarm mode Indicator light:LED visibility under 8000LX visible light Buzzer: above 60dB (distance: 60CM) Protection class IP54 Working environment - 10 ℃ to 40 ℃; Below 80% RH Storage environment 10 ℃ ~ 60 ℃; Below 70% RH .Precautions: 1: The wrist alarm is not a voltage tester, and it is prohibited to use it as a voltage tester. Because high-voltage operation is very dangerous, operators must undergo rigorous training and obtain corresponding high-voltage operation certification before using the instrument for field testing. 2: When using, please wear the alarm on the bare skin of your wrist and keep the case close to the skin. Make the triangular symbol on the surface of the alarm point point toward your fingertip. 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 be greatly reduced. 5: If the alarm is hung on the sleeve of work clothes or rubber gloves, the sensitivity will be greatly reduced. 6: When the alarm clock gets wet in the rain, please take out the battery and dry it naturally in a cool place.
