s I G nAL CLAM pI n G
The optional Signal Clamps can be used to apply
the Genny4 locate signal safely to a pipe or cable
up to 215mm in diameter without interrupting the
supply. Signal clamps are not suitable for connecting
around lamp posts.
Plug the Clamp into the Genny4 accessory socket. Place the Clamp
around the pipe or cable ensuring the jaws are completely closed.
Switch the Genny4 on then open and close the Clamp. If the jaws are
closing correctly there will be a change in tone as the jaws are closed.
An earth connection from the
Genny4 is not necessary but
optimal signal transfer is only
generally achieved if the target line
is grounded at both ends. This is
usually the case with power cables.
Use the C.A.T4 to scan the area
for the target pipes or cables
(see 'Locating with C.A.T4').

Induction is a convenient and quick way of applying the Genny4 locate
signal to a pipe or cable where limited access does not permit the use
of Direct Connection or Signal Clamping.
Place the Genny4 over the assumed position of the conductor and
in-line with its assumed direction. Move at least 10m away and use
the C.A.T to scan for pipes and cables (see 'Locating with C.A.T4').
Working too close to the Genny4 may give false readings as the
C.A.T4 will detect airborne signals directly from the Genny4 rather
than the target line. For best results, repeat the scan with the Genny
facing at 90˚ to the first scan position.

Locating with C.A.T4
C.A.T An d G e n ny fU n CTI onAL Te sT
Regularly check your C.A.T4 and Genny4, in all modes, over a
cable which gives a response you are familiar with.
Place the Genny on the ground, switch on and check for an audible
sound. If no sound is heard or the low battery warning light is
flashing, replace the batteries before use.
Switch on the C.A.T by squeezing the trigger, checking for an
initial 'chirp.' A low tone indicates low batteries. If no sound is
heard, replace the batteries before use.
Rotate the C.A.T function switch and check that the appropriate
letter is displayed in each position of the switch.
Set the C.A.T to Genny mode at maximum sensitivity, hold at
waist height pointing toward the Genny with the flattest part of
the housing parallel to the ground and check that the C.A.T can
detect the Genny up to 15m away with a clearly audible sound.

Grip the handle. Press and hold the trigger and listen for the bleep
indicating the batteries are OK. Replace both batteries if there is no
bleep or if the battery icon is flashing.

When a service/calibration is due in 31 days or less, the screen
will display 'CAL' at startup, followed by the number of days until a
service /calibration is due.

enabled units are equipped with a system which does
not permit them to function once they are beyond the expected
service/calibration date. If
immediately return your C.A.T for service/calibration.
Do not attempt to use a C.A.T4 for tracing pipes or cables
outside its calibration period. If in doubt, contact the person
responsible, or Radiodetection.
