7.1 Connection of frequency generator
If this method can be used, galvanic coupling is always the best method.
Application:
-
for cable routing
By direct galvanic connection the highest possible
ranges can be obtained.
Do not increase current unnecessarily because
adjacent lines might otherwise be induced too.
The inverse current is conducted via earth. Please note, that this connection method can
cause fault measurements if used on underground lines (e.g., in residential or industrial
areas), because the inverse current is also conducted via other cables and lines which are
located by the UL 30 unit with a very strong audio frequency signal.
Clip on device AZ 10
The clip-on device can be used with dead and live cables.
Applications:
-
Routing (house connection, water,
telephone, gas)
Connection directly on the Audio Frequency Generator. Maximum load of clip-on device
approx. 30VA. The highest efficiency is reached by applying the clip-on device in the middle
of the cable.
