When a tone signal is detected by the probe, the signal LED will serve as a signal strength indicator.The brighter the LED, the stronger the tone signal detected. When the 200FP is ON but not detecting a signal, the signal LED will flash momentarily (every 4 seconds) as a visible ON indicator and reminder. In addition, the 200FP has been specifically designed to filter out all power-related noise to eliminate “Power Line Hum.” The unit is constructed of durable ABS plastic, and an optional leather carrying case, 200C, is available. The 200FP Filtered Tone Probe is designed to identify and trace wires or cables within a group without need of removing insulation. to this series (detailed overleaf) Tempo supply a number of application specific designs. The tone and short circuit test functions are only applied to Line 1 using the modular plug. The 200FP Filter probe offers three types of noise filtration. When a short circuit is detected, an audible signal will be heard (77HP only). These testers are housed in high impact plastic cases, and each is powered by one 9 volt battery.Ī three-position toggle switch controls the modes of operation, and bi-colored Light Emitting Diodes (LEDs) display line polarity for Lines 1 and 2 (Line 1 only for 77M-G). The 77HP-G/6A Tone Generators is intended to identify the conductor within a bundle, at a crossconnect point, or at the remote end.
