The PoE checker is consists of two parts: an Emitter and a remote. It has functions such as standard and non-standard PoE equipment detection, PoE power online test, network cable continuity test, DC power test, switch loop-back test and other functions. Therefore, it is a perfect for security monitoring, communication wires, integrated wiring and other weak current systems.Specifications:Material: ABSTransmitter Specification:CONTINUITY FUNCTION:Cable Types: STP/UTPMax Testing Range: 600mWire Mapping: Emitter + remote, emitter + switch/routorPOE FUNCTION:Test Range: DC5-60V PoE switchStandard Identify: 802.3af/at(standard/non-standard)Test Range Power: 0-18WPOWER FUNCTION:Voltage Test Range: DC0-60VCurrent Test Range: 0-3APower Test Range: 0-180WDisplay: LCD 128*64mm, with back lightInput Voltage Protection: DC48V, 5mAMax Working Current: ≤80mALoopback: Compatible with 10M, 100M, 1000M switchPower Supply: 3 * 1.5V AAA battery (NOT included)Remote Specification:Ports: RJ45Function: Wire mapping for network cableInput Voltage Protection: DC48V, 5mAEmitter Size: 125 * 70 * 28cm / 4.92 * 2.76 * 1.1inRemote Size: 65 * 37 * 23cm / 2.56 * 1.46 * 0.91inEmitter Weight: 123g / 4.33oz Remote Weight: 24g / 0.86ozPackage Weight: 240gPackage Size: 21.6*11.2*4.6cmPackage List:1 * Emitter1 * Remote1 * Crocodile Clip Test Line2 * Cable Lead1 * Carry Bag1 * User Manual (English)
