The Triplett ETFB10 combines a Non-Contact AC Voltage and a Optical Fiber Detector. It has a 50 to 1000V AC voltage range with high sensitivity that allows it to detect low voltage AC wiring (50V) commonly found in low power systems, process controllers, garage door openers, power relays, coils, alarm sensors and controls. The Triplett ETFB10 allows the user to quickly determine the presence of optical fiber activity for single and multimode fiber, patch cords and ports. It features a built-in work light in the tip, flashlight in the back, low battery indicator (<2.4V), auto power off after 5 minutes of inactivity and is safety rated at CAT IV 1000V.
