Whenever it is possible to embrace the traced wire or pipe it is recommended to use the
appropriate current clamp instead of the receiver’s inductive sensor (see figure below).
By using the clamp, the signal selectivity will considerably improve.
Always keep maximum distance between current clamp and R10K.

For searching a fuse in a group of them the selective probe should be applied.
With it the housing of the fuse or wire must be touched at the right angle.
Find the best signal by rotating the probe.
Keep maximum distance between R10K and selective probe.
Note: keep fingers behind the probe barrier to avoid electric shock and access of live
parts.
