10.4 Sensitivity settings
In order to cover a measuring range from the smallest leaks (0.1 l / min) up to large leaks,
the LD 500 has different measuring sensitivity levels:

0 – 60dB

10 – 70dB

20 – 80dB

30 – 90dB

40 – 100dB
Note: The measurement sensitivity level 0 -60dB (most sensitive setting) can only be used in manual
mode. The mode can be changed by pressing the "Mode Switch button".

HiSn -- manual sensitivity mode

Auto -- automatic sensitivity mode
The individual stages can be selected in manual mode by pressing the "Sensitivity" setting button. The
steps are changed to the next step each time the button is pressed.
The„Auto“
setting allows you to automatically switch to the preferred sensitivity level
for the Testo Sensor LD pro. However, this requires a min. measuring time of 2 seconds.

the membrane keypad). When switched on, the display shows a laser warning symbol.
