500XP is a pair tracing probe that is designed for technicians in the world’s premier telecommunication companies. It is part of Tempo’s “Nautilus” range of tough and robust products being built compact yet highly water and impact resistant. Even in the tough environment of your telecom technician we warranty this for three years. It is built around a digital signal processing engine that can be set to different modes to eliminate noise that can often interfere with the signal you are seeking making your job that little bit easier. We have also used that signal processing capability to detect if there is any risky power hum near the tip perhaps from a nearby electrical cable, warning the user if this is found. With super high input impedance and over 30 dB of adjustable gain coupled with the large loudspeaker or headset complemented with signal strength indicating LEDs you can use this probe in the noisiest or quietest environments.
