1、Main Application: This is a multi functional cable tester for testing telephone or network cables, which adopts automatic scanning mode for fast testing. 2、Anti Falling Design: This wire stripper set adopts linear shape conforms to the ergonomic design. Anti fall and anti light design, more in line with on site construction, very practical! 3、Scope of Application: The scope of application of network stripper, round wire (UTP, STP), flat wire and multiple transmission lines 3.2mm to 9.0mm. Scope of application of coaxial stripper, coaxial cable RG58, RG59, RG62, RG3C, RG4C. 4、Easy Carrying: Comes with a storage bag that you can well arrange and store these tools wherever you go, easy for you to carry around to help with your work. 5、Wide Application: This tool kit can be used in many scenarios, like home, office, laboratory, dormitory, repair shop and in daily life. Item Type: Network Repair Tool Kit Material: 45# Steel Specification of RJ Connector Crimping Pliers: 4P, 6P, 8P Tester Battery: 1 x 9V dry battery (delivered without battery) Applicable Scope of Threading Knife: Telephone line, network line, monitoring line Scope of Application of Coaxial Stripper: Coaxial cable RG58, RG59, RG62, RG3C, RG4C Scope of Application of Network Stripper: Round wire (UTP, STP), flat wire and multiple transmission lines Approx. 3.2 to 9mm / 0.13 to 0.35in Test Method of Cable Tester: 1. Test the twisted pair 1, 2, 3, 4, 5, 6, 7, 8, G one by one (pair) to determine which (pair) is wrong, short or open. 2. Switch "OFF" is off, ON is normal test speed, and "S" is slow test speed. Main tester: 1-2-3-4-5-6-7-8-G Remote tester: 1-2-3-4-5-6-7-8-G (RJ45) 1-2-3-4----------（RJ11） If the wiring is abnormal, it will be displayed as follows: a. When a network cable, such as Line 3, is open circuit, the No. 3 lamp on the main tester and remote test terminal does not light up. b. When several lines are not connected, none of them will light up. When less than two network lines are connected, none of them will light up. c. When the network cables on both ends are out of order, for example, 2 and 4 lines are out of order, the display is as follows: The main tester remains unchanged: 1-2-3-4-5-6-7-8-G Remote test end: 1-4-3-2-5-6-7-8-G d. When two network cables are short circuited, the main tester will not light up, while the remote test terminal will light up slightly for the two lines that are short circuited. If more than three (including three) lines are short circuited, the lights of all short circuited lines will not light up. 4. If testing the distribution frame and wall base module, two matching jumpers (such as 110P4-RJ45) are required to lead to the tester. 1 x Cable Pliers 1 x Thread Clipping Knife 1 x Wire Stripper 1 x Network Tester 30 x RJ Connector 30 x RJ Connector Cover 1 x Storage Bag 1 x RJ45 Coupler 1 x 3 Way Coupler 50 x Strap
