TONE mode (send tracing tone)
When switching to TONE mode, the EasyFinder starts as default with alternating or
warbling tone frequencies. The EasyFinder has six easily selected tracing tone frequen-
cies. Briefly press the SOLID button (less than 2 seconds) to transmit a trace frequency
at precisely 1 kHz.
If you press the button for more than 2 seconds, a trace frequency of 2.9 kHz is gener-
ated. Additional pressing of 2 seconds switches to 577.5 Hz.
Press the ALT button for less than 2 seconds to send alternating frequencies of 880
Hz/1 kHz. Press it for more than 2 seconds to switch to an alternating frequency of
1.9 kHz/2.6 kHz. Another 2 seconds switches to a intermittent 577.5 kHz tone.
The high trace frequencies have two advantages. First, the human ear is the most
sensitive at 2,600 Hz and second, these two frequencies lie outside the signaling
frequency range of telephone systems.
The LEDs to the right of the buttons indicate the activated trace tone and can be seen
from a distance. The trace signal can be injected without interfering with active (volt-
age present) telecommunications and data lines.
Tracing cables
When tracing cables and wires, even within a wall, clip the black test lead of the
EasyFinder to ground and the red test lead to a single wire or a wire pair. Select the
trace frequency. The selected tone is transmitted and can be tracked without contact
using the PROBE for up to 60 cm from the cable. Tone will be transmitted even on
shorted pairs to a maximum of 200 m. The PROBE is used to trace the cable.
This is done by pressing and holding the LOW or HIGH button. To locate a signal at a
greater distance or to trace a weak signal, press the HIGH button. In the case of large
cable bundles in a distribution box or rack, the PROBE is moved flat above the bundle
while pressing the HIGH button. After the cables are located using the strongest
signal, press the LOW button to find the precise location of the desired cable.
The highest signal is always above the desired cable. When tracing shielded cables,
connect the red test lead to the shielding and the black test lead to ground
(such as a protective conductor or water line).
If there is no shielding, connect across two different pairs within the cable. If the
shielding is grounded, it must be isolated at both ends. Do not connect across pairs
carrying Voice and pairs carrying Data.
