Display graphical wire mapping, opens, shorts. BUT PLEASE NOTE: our device works by TDR theory, which is mainly to test long cables. If cable is ＜20m, it will display cable is too short or open. Thus, when measure length, pls try a long cable, for other functions, short cables are acceptable. pls kindly notice this. - ⏩【POE Testing】AT278 Network Cable Tester can detect Ethernet network for POE(Power over Ethernet) existence and to know which pins are providing power and detect how much voltage. - ⏩ 【PING Function 】AT278 Cable Tester is designed for testing network performance, data packet, min & max time. Test the reachability of a host on an Internet Protocol(IP) network. It reports errors, packet lost, and a statistical summary of the results, including the minimum, maximum, the mean round-trip times. - ⏩【AC Filter】Trace cables with AC fliter, quickly find the targeted cable without AC noise. Available on common switch & PoE Switch. Also, it is safe to find cable in standard types of PoE switches, which won't burn out the device. - ⏩【Aditional Highlights】Come with TF card included to export data to PC; Voltage detector: included in receiver (90-1000V); Rechargeable Lithium battery for more efficient work. Low voltge alarm function and automatic delay power on-off. Big LCD color screen 320*240 and lighting lamp in darkness. Hub blink to locate network port by the flashing port light on a server/switch/hub/router port. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07WRV3N5F | | Best Sellers Rank | 1,005,411 in DIY & Tools ( See Top 100 in DIY & Tools ) 799 in Network Testers | | Brand | KOLSOL | | Colour | AT278 | | Customer Reviews | 4.0 4.0 out of 5 stars (92) | | Item Weight | 771 g | | Manufacturer | KOLSOL | | Manufacturer Part Number | WIWUAT278-K | | Maximum Operating Voltage | 1000 Volts | | Minimum Operating Voltage | 3.3 Volts | | Model Number | AT278 | | Power Source | Battery Powered | | Specification Met | reachability | | Style Name | Modern | | UPC | 889327032716 | ## Product Details - **Brand:** KOLSOL - **Colour:** AT278 - **Item weight:** 771 g - **Power source:** Battery Powered - **Style:** Modern ## Images ![Network Cable Tester, Network Tester with TDR, Network Toner Tester with AC Filter, AT278 Multi-Functional Wire Tracker for RJ45, RJ11, BNC, Metal Cable, PING/POE - Image 1](https://m.media-amazon.com/images/I/71p0UhPNcGL.jpg) ![Network Cable Tester, Network Tester with TDR, Network Toner Tester with AC Filter, AT278 Multi-Functional Wire Tracker for RJ45, RJ11, BNC, Metal Cable, PING/POE - Image 2](https://m.media-amazon.com/images/I/71XpLR6JBbL.jpg) ![Network Cable Tester, Network Tester with TDR, Network Toner Tester with AC Filter, AT278 Multi-Functional Wire Tracker for RJ45, RJ11, BNC, Metal Cable, PING/POE - Image 3](https://m.media-amazon.com/images/I/71bwYkHoEZL.jpg) ![Network Cable Tester, Network Tester with TDR, Network Toner Tester with AC Filter, AT278 Multi-Functional Wire Tracker for RJ45, RJ11, BNC, Metal Cable, PING/POE - Image 4](https://m.media-amazon.com/images/I/71eFN0VrgVL.jpg) ![Network Cable Tester, Network Tester with TDR, Network Toner Tester with AC Filter, AT278 Multi-Functional Wire Tracker for RJ45, RJ11, BNC, Metal Cable, PING/POE - Image 5](https://m.media-amazon.com/images/I/71t+-0nWqjL.jpg) ## Questions & Answers **Q: Will this measure capable bandwidth e.g. 5Gbps vs. 10Gbps?** A: Sorry the tester does not support this. **Q: What does split pair 14, 25 mean?
