CT33 User Manual v. X1.0 30
Task: An open fault (cut) in a floor heating cable needs to be traced.
-
Several factors affect tracing an open in a heating cable, such as what cable type is at hand, is the cable
fully cut or just one wire and what kind of grounding there is to concrete reinforcement. All these require
carefulness while tracing and yet it is possible that exact fault location can’t be determined.
-
CTT33:
Connect one transmitter output to the cut wire. Connect the second output to the uncut wire & cable
shielding and connect both of them to an auxiliary grounding, preferably using a ground pick. Do not use
electrical wiring's PE!
-
CL43:
Use LA43 probe. Monitor signal strength along the cable's route. In this case signal is typically weak
and no minimum can be detected. At fault spot the signal gets even weaker.
