in this manual

(e) The line is now energized

Using INDUCTIVE Energizing

  Another common method to energize a

line is by induction   When the signal jacks of the Model 

X are not

being used  the transmitter case emits an INDUCTIVE field  which  when
placed over the target line  will energize it   This method requires none
of the underground line to be exposed   However  INDUCTIVE mode is
best used on isolated lines and away from areas congested with many
services and metallic objects

(a) Make sure both SIGNAL jacks are empty  and activate the

transmitter

(b) Select the operating frequency and the output level as described

previously in this manual

(c) Close the latch covers on the case  and position the case over the

underground line so that the hinge of the case is roughly in line
with the target line   Also  it is recommended that the transmitter
case be turned so that the hinge axis is offset about  ° from the
supposed direction of the underground line

(d) The line is now energized

PASSIVE Energizing

  Finally  the user should be aware that some lines

are “always” energized   An example of this kind of line is a power line
Power lines that are actively in service constantly carry AC current   This
current is typically at a frequency of 

 Hz  with harmonic components

at multiples of 

 Hz (i e  

 Hz
