AMPLIFIER PROBE Figure 1 Figure 2 FEATURES ● The Amplifier Probe is designed to identify and trace wires or cables within a group without damaging the insulation. ● Works with any Tone Generator to identify wires. ● Volume control for increased sensitivity and adjustable to suit work environment.
INSTRUCTIONS ● Connecting the tone generator. In terminated working cables : Connect one test lead to a terminated wire and the other test lead to earth or equipment ground.(See figure 2) In unterminated or non-working cables : Connect one test lead to an unterminated wire and the other test lead to another unterminated wire.
FEATURES ● Red and black test leads with a standard 4 conductor modular cord and plug. ● A 3-position toggle switch controls the modes of operation and two bi-colored LEDs display line polarity for Lines 1 and 2. ● The tone and continuity (cont.) test functions are only applied to Line 1 using the modular plug.
INSTRUCTIONS All of the following tests can be performed by using the red and black test leads or the modular plug. NOTE : When using the modular test plug, the polarity test function applies to Lines 1 and 2. The continuity and tone functions ONLY apply to Line 1.

● Verifying lines (switch to "off" then "cont") 1. Dial the line to be verified. 2. While the line is ringing, connect the RED lead to the RING SIDE of the line and the BLACK to the TIP. 3. In the "OFF" position, the indicator lamp will flicker "RED and GREEN"...

● Testing continuity (switch to "cont") CAUTION : DO NOT CONNECT TO ANY ACTIVE AC OR DC CIRCUIT IN THIS MODE. 1. Connect the test leads to the subject pair. 2. Use "cont" position. 3. A bright "GREEN" light indicates continuity. The LED will not glow if the line resistance exceeds 12kΩ.
● Coax testing 1. To test unterminated coax, connect red to outer shield and black to center conductor or red to outer shield and black to ground. 2. To test terminated coax, connect red to connector housing and black to center pin or red to connector housing and black to ground.
