NOYAFA NF-8508 Tester LAN network cables Optical power meter Tester LCD length meter Wiremap Tester cable locator Full Set Characteristics: Transmitter testing function: including cable continuity testing, cable scanning, port flashing, cable length measurement, PoE test, QC testing for crystal headband, OPM (optical power meter) and VFL (visual location fault) functions. POE test: automatic identification of midspan/endspan/power by 8 cores, automatic identification of standard and custom device. Optical power meter: 850/1300/1310/1490/1550/1625nm wavelength switching; Unit switching at dBm, dB or mw, uw, nw; I REF switch. Visual fault location function: detect and locate fiber cracks, as well as problems such as weak joints, fiber bends or cracks. Receiver function: sensitivity adjustment, 300m shielded network cable without load/not empty shielded network cable, NCV detection, lighting function, etc. Non-contact voltage detection: The receiver can be used to detect the AC voltage of home electrical wiring. Lighting function: receiver designed with lamp for additional illumination of work areas during operation. Battery powered: both transmitter and receiver are built into 1500mAh polymer battery, no need to replace battery, Type-C charging, with charging indicator and low battery indicator. Other settings: backlight brightness (level 1/2/3), backlight time (MAX/1min/30S/15S), auto-off time (15min/30min/1h/2h/off), red lampa flash under VFL function (fast flashing/slow flashing/on. ). Wide applications: suitable for network line engineering and maintenance work of telecommunications, computer, other metal wires, etc. Technical data: Material: ABS Cable Type: CAT5/CAT6 Voltage: 60V Package Weight: 586g / 20.67oz Transmitter: Connection Maps Port: RJ45 Remote continuity: 300m Cable Sequence and Fault Test: Yes STP/NTP: yes Short-circuit reminder: yes Anti-jamming and normal mode: yes Audio Frequency Transmission: 455KHz Audio transmission distance: RJ45 300m NVL: 10mW Power meter: 850/1300/1310/1490/1550/1625nm (wavelength) Crimping: RJ45-8 cores, minimum length is 10cm Low voltage prompt: < 3.5V 0.1V, power indicator flashes Power supply: 3.7V 1500mAh lithium polymer battery Size: 148*70*32mm / 5.83*2.76*1, 26in Receiver: Scanning Current: 300mA Remote continuity: 300m NCV detection: yes Lampa: yes Low voltage prompt: yes Power supply: 3.7V 1500mAh lithium polymer battery Size: 198*50*28mm / 7.80*1.97 * 1.10in
