How to read the displayed data
The LCD display contains the same icons as previously described. The sole
difference is:
1. Indicates that a cable for ultrasonic sensor is connected between the sensor
and the detector.
2. Indicates the data (amount of ultrasonic sounds) given in dBµV.
The icon with a flexible sensor.

ARABOLIC SENSOR
Main field of application
This typical waveform concentrator equipped with a laser pointer is used to detect
ultrasonic phenomena, at short or large distances, with a very high precision. The
main applications are the leak and electrical arcing detection.
Description
This sensor allows is an exceptional highly unidirectional ultrasonic measurement
tool that minimizes background noises and concentrate on distant leaks or
focuses on corona discharge and electrical arcing at distances more than several
meters.

The dish is transparent to easy visualize the object while measuring. For this
same purpose of “pin pointing the object to measure” this parabolic concentrator
has two sights
: a “rifle-sight-shaped” sight and a very effective laser pointer sight.
