Triplett Mitigator Loop Coil – 3232 - Manual (Page 2)

Triplett Loop Coil
Instruction Manual
NOTE:
This manual covers both the 60Hz and 50Hz versions of the Mitigator. The parameters shown in [ ] are
for the UK where the standard power line is 50Hz/240 Volts. Depending upon your situation, line voltage
may vary from 100 - 250 Volts. Please consider this while reading the following text.
SECTION 1: INTRODUCTION
The Triplett 3232 Loop Coil is a rugged, weather resistant coil designed to aid in the search for and
location of magnetic fields radiating from power lines.
As an accessory item for the Triplett MITIGATOR, it is intended to be electrically compatible with exist-
ing Loop Coils, such as the CCS105. Unlike the ‘105, however, the 3232 is constructed from a semi-
rigid polyurethane that is highly resistant to fracturing and impact damage.
SECTION 2: MITIGATOR APPLICATIONS MANUAL
The Triplett MITIGATOR Applications Manual provides background information that can be helpful in
understanding magnetic fields, harmonics, Ground Return Current, etc. It is, therefore, recommended
that the Loop Coil user read the appropriate sections of the MITIGATOR Applications Manual in order to
better understand the causes and solutions for induced harmonic noise problems.
References will be made throughout this test to additional information that may be found in the MITIGA-
TOR Applications Manual.
SECTION 3:
CONNECTING THE LOOP COIL TO THE MITIGATOR OR A SIMILAR TEST SET
An interconnecting cable is supplied with the Loop Coil for the purpose of connecting the Loop Coil to
a test set that utilizes standard female banana jacks spaced on 3/4" centers. The end of the cable
connecting to the MITIGATOR must be plugged into the TIP and RING input jacks. The polarity of this
connection is not critical.
In some cases, the user may wish to extend the length of the interconnecting cable. Although the
supplied cable is shielded, a shielded cable is not really required, nor is the gauge of the wire critical.
Twisted pair is probably the best because it doesn’t pick up as much noise as wires that are not twisted.
The lower noise pickup of twisted pair is usually not very important in this application, however, and if
more available than twisted pair, common lamp cord (“zip” cord) can be used. The connectors on both
the Loop Coil and the MITIGATOR are standard “5 way binding posts” and will accept bare wire con-
nections.
SECTION 4: MITIGATOR OR TEST SET INPUT IMPEDANCE
To use the Loop Coil with the MITIGATOR, set the INPUT (F1) on the MITIGATOR’s MAIN MENU to
LOOP COIL. For use with an alternate test set, set the test set to “bridging” input.
SECTION 5: BASIC LOOP COIL TEST
The Backlight circuit in the MITIGATOR generates some residual noise. It can usually be measured by
placing the Loop Coil next to the left side of the MITIGATOR’s case. The signal is usually somewhere
between 400 and 600Hz. In order for this signal to be present, the Backlight must be turned ON. This
source of magnetic field can be used as a Loop Coil check if the user suspects that the Loop Coil is not
functioning.
