Fig. 4: Localization of protection devices
5. Move towards the control panel next to which the intermittent sound is faster and move
the sensitive element in different directions (see Fig. 4 – left side).
6. Slowly move the sensitive element of the receiver above the protection devices found
within the panel until the presence of the signal generated by the transmitter is
detected. In this condition, the red LED turns off, the green LED turns on and the
internal buzzer is fast and continuous.
Suggestions for test optimization

Reset the receiver (see § 5.2) before starting the scanning test in order to always
detect the signal with the highest intensity.

Carry out the scanning by resting the sensitive element on the upper part of the
protection device.

In case of difficulties in detecting the searched for protection device (e.g. two adjacent
devices cause the instrument to sound with the same intensity), turn the receiver by
90° (see Fig. 4 – right side) in order to make the search for the signal easier. In
general, follow the angle at which the protection device was installed within the panel.

The first signal with strong intensity detected might not be the one searched for.
Since the technology for scanning is comparative, it is always necessary to carry
on this operation on all protection devices which potentially control the socket to
be tested.

In case the red LED starts flashing and then turns of during the test, press the /Reset
key to reset the instrument in order to detect again the signal with the strongest
intensity.
