10.3 Sensitivity level
Ultrasound levels can be understood as a "loudness" of the leakage.
With the "Sensitivity" button, the sensitivity of the Testo Sensor LD basic can be adjusted to the
environment, which strongly influences the acoustic behaviour of the device and increases or
decreases the valid value range. A reduction in sensitivity reduces the range of the leakage .
The sensitivity levels or the automatic function are selected via the "Sensitivity" button.
