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.
Sensitivity levels
0
– 60 dB = Highest sensitivity level of the device (use with small leaks and no noise
10 – 70 dB = Leakages and noises get "less noisy", the range is reduced.
20 – 80 dB = Leakages and noises get "less noisy", the range is reduced.
30 – 90 dB = Leakages and noises get "less noisy", the range is reduced.
40 – 100 dB = Most insensitive stage (large leaks, many noises
→
for heavy-duty application)
The LD basicoffers a manual selection as
well as an automatic function
"Auto " for
setting the sensitivity.
Selection is made by pressing the
"Sensitivity" setting button.
When "Auto" is selected, the LD basic
selects the best possible sensitivity level.
