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

1. TONE mode (send tracing tone)
When switching to TONE mode, the
E
ASY
T
EST
starts as default with alternating or
warbling tone frequencies. The
E
ASY
T
EST
has six easily selected tracing tone
frequencies. 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 generated. 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 (voltage present) telecommunications and data lines.
The
KE4xx, KE7xx
and
KE8xx
are high-impedance for data signals, which makes it
possible to transmit trace signals on active telephone lines with ISDN and ADSL
systems without causing interference. The
KE4xx
further reduces possible
interference by sending sinusoidal signals.
A. Tracing cables:
When tracing cables and wires, even within a wall, clip the black
test lead of the
E
ASY

EST
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 60cm
fr
om 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

on. Then the units starts in ALT mode. To change to SOLID - press the SOL
button. To trace a coax cable take care that the far end is open and not groundet. If the
cable is groundet or connected on the far end you will not be able to get a trace signal.
This because the shield prevents this.
Test of fiber optic cables
In the fiber optic test mode the unit works as a visible laser source. To protect the user -
transmitted power is less then 1 mW, Laser Class 2.
Please do not stare into the beam!
The universal jack fits fiber plugs with a 2.5 mm ferrule. If your system is using 1.25 mm
ferrules - please use the 2.5 to 1.25 mm adapter, Art. No.: 1400070.
The jack is equipped with a ceramic spring to protect the ferrule to reduce the chance
that the plug will accidentally come out. The ceramic material protects the ferrule
against metallic contamination.
Start Fiber testing
Turn the
KE800
on as described before. The Unit starts in TONE mode for copper
tracing. Plug the fiber with the ferrule into the universal jack. To turn on the laser source -
press the SOLID and ALT button together for > 1 Sec. The
KE800
indicates the LASER
Mode by a turn-on tone and flashing ALT LED and Laser source. The LASER mode is
flashing at 1 Hz not modulated. By pressing the SOLID button the mode changes to
CW - not modulated. By pressing either the ALT or the SOLID button > 2 seconds, the
laser mode changes to modulated. The modulation frequency is audible and starts with
270 Hz. Release and press again changes the modulation to 1000 Hz and then to DC
again. If you use a power meter with demodulation feature at the far end to detect your
light, you will see the frequency in the display.
Regardless of the laser mode you will be able to spot light leaks from bad connections,
sharp bends and breaks, as well as identifying the far end of the connected cable.The
trace distance is more than 6 miles.
