Introduction

This manual is intended to familiarize personnel with the safe operation and maintenance procedures for the Tempo 200EP Inductive Amplifier.
Please read this entire manual before operating the tool and keep this manual available to all personnel.
Replacement manuals are available upon request at no extra charge.

Safety

Safety is essential in the use and maintenance of Tempo tools and equipment. This instruction manual and any markings on the tool provide information for avoiding hazards and unsafe practices related to the use of this tool. Observe all of the safety information provided.

Description

The 200EP Inductive Amplifier, when used in conjunction with any Tempo tone generator, is designed to identify and trace wires or cables within a group without damaging the insulation.

Features include:

• Spring-loaded ON/OFF button.
• Adjustable volume sensitivity control.
• Recessed terminal ports for handset connection.
• Resistive plastic carbon-fiber tip prevents accidental shorts when probing wires.

Operation

1. Connect the test set leads of a Tempo Tone TestSet to the subject pair. In the case of a single conductor, connect the RED lead to the subject wire and the BLACK lead to earth or an independent equipment ground. See the instruction manual provided with the tone generator for details. See Figure 2.

2. Place the Test Set in the "TONE" position.
3. To activate the 200EP, press and hold the square spring-loaded ON/OFF button. This button must remained depressed to operate. Hold the tip of the probe near the tone generator and listen for the tone. This verifies that the tone generator is working, and identifies the sound of the tone (steady, warbling, etc.).
4. Once activated, the volume control can be adjusted to suit the environment. Reception can be increased to overcome noise (e.g. vehicular traffic, airplanes or engine room), or decreased to reduce interference (e.g. computer/date hum or AC buzz).
5. The 200EP is equipped with recessed terminal ports for connecting a lineman's handset. Attaching the handset automatically activates the amplifier. The handset must be in the TALK position to receive the tone.
6. Touch the tip of the 200EP to the insulation of each suspect conductor. Reception of tone will be loudest on the subject wire and detection may be improved by separating the wires from the group. If more than one pair or single conductor is carrying the tone, decrease the volume until only the subject conductor is left with tone, insuring that positive identification has been made.

Note: To use the 200EP without pressing the ON/OFF button, connect a jumper, a telephone test set (in Talk mode), or headset to the recessed tabs near the speaker.
