Operation
Using the probe tip:
The noise is recorded via the probe tip (
1
) when the internal sensor is used for the measuring.
The probe tip can be detached. You can unscrew it when necessary and exchange it for another
measuring head or fit the provided extension rod between the probe tip and the sensor.
Using an external sensor:
The 5-pin socket (
3
) underneath the device can be used to connect up an external sensor to the
device, e.g. a ROLeak Aqua 3Plus floor microphone.
The device must be switched off before an external sensor is attached to it. Take note of the
markings on the plug and socket. The plug must click into place.
