description southwire advanced dual range ncv 12 1000v ac southwire 40150n is an advanced dual range non-contact ac voltage detector with a convenient work light. it features audible and visual indication of ac voltage on two ranges: 12 to 1000v and 100 to 1000v. bi-color led verifies tester is on and range selected, red led and beeper indicates voltage is detected. the yellow led light indicates that the tic tester is in low voltage mode. the non contact voltage tester features a rugged ip67 waterproof and dust tight housing and features a built-in forward and rear facing flashlight for user convenience in dim lighting. with electricity safety is paramount so it features cat iv rating at 1000v and is ul listed. this unit is not designed for use with tamper resistant (tr) outlets. this unit is built to help electricians have a great indicator of live power. it features a pocket clip for easy access and storage and the low power feature will indicate when the batteries need to be changed. testing a wire is very easy with this unit. california proposition 65 warning. features pen style non contact electrical tester for easy detection of ac voltage audible and visual indication of ac voltage on two ranges:12 to 1000v and 100 to 1000v rugged ip67 waterproof and dust tight housing bi-color led verifies tester is on and range selected, red led & beeper indicate voltage is detected rugged ip67 waterproof and dust tight housing with a 6' drop test rating multi-functional this electric tester features a built-in forward and rear facing flashlight for user convenience the tester will not detect voltage if the voltage is dc; wire is shielded or in a grounded metal box or conduit; the user is not grounded or is isolated from earth ground; the detector tip cannot be fully inserted into the electrical outlet; the electrical outlet is a tamper resistant design; the user is not holding the detector or the user’s hand is insulated from the detector (i.e. with a glove); the voltage source or wire is partially buried. specifications ac voltage 12 to 1000 acme tools brand name southwire acme tools part number 40150n assembled depth (in) 1.182 assembled height (in) 6.501 assembled weight (lbs) 0.15 assembled width (in) 1.182 battery quantity required 2 battery size aaa capacitance capable no case included no continuity beeper no country of origin china data hold no dc polarity indicator no dc voltage n/a digital display not required electronic yes globaltradeitemnumber (gtin) 00032886963445 height (in) 6.501 package contents 40150n advanced dual range ncv 12-1000v ac package depth 1.773 package height 8.661417322834646 package weight 0.15 safety rating cat iv 1000v, ul listed tester type non-contact tests continuity no upc 032886963445 voltage compatibility ac only
