First place the batteries into the battery compartment of the LD6000 and connect
all the components which you require to perform your specific measuring operation.
Headphones:
Connect the headphones to the headphone jack of the LD6000 if necessary
(see chapter 4, legend item
The headphones have been designed specifically for use with the LD6000
and for carrying out acoustic leak detection. The state-of-the-art electronics
incorporated in the high-quality hearing protector capsule ensure optimal results
while providing excellent soundproofing qualities.

5.1.1. Connecting the Microphones for
Acoustic Leak Detection
Please be sure to use one of the following microphones only when carrying
out acoustic leak detection with the LD6000.
LD6000 BM universal microphone
The LD6000 BM is a universal microphone which can be either be used as a
probe microphone or a contact microphone. Connect the LD6000 VL extension
kit to the universal microphone and use as a probe microphone to pinpoint leaks
or screw on the optionally available magnet and use as a contact microphone
when carrying out leak detection where ferromagnetic pipes, for example, are
involved. The contact microphone can then be used in connection with the LD6000
DA tripod adapter as a ground microphone to locate any potential leaks.
Using the LD6000 BMW Ground Microphone
The LD6000 BMW is a wind-protected ground microphone which can be used when
carrying out leak detection on solid, stable surfaces. The LD6000 BMW can be
combined with the LD6000 DM tripod magnet for use on loose or unstable surfaces.

selection of predefined filters as well as a selection of user-defined filters which
can be configured in the setting window Frequency Range.
The settings of the high pass filter (HP), the low pass filter (LP) and the maximum
breadth of the colour spectrum can all be changed.
Repeat the procedure as described in Time and Date (see chapter 6.4.1.) to enter
the configuration you have selected.
6.4.6. Hearing Protection
The LD6000 is equipped with an automatic sound absorber which ensures that
hearing protection guidelines according to BGV B3 (formerly VBG 121) (BGV Accident Prevention & Insurance Association) are complied with when used with
the headphones included in the scope of delivery.
The noise protection intensity of the headphones can be adapted individually to
suit the user. The intensity ranges from 0 (relatively low) to 3 (maximum). Each
of the three stages complies with the requirements as laid down in VBG 121.
The configuration corresponds to the procedure for setting the time
and date as described in chapter 6.4.1.
In order to be able to carry out acoustic leak detection with
the LD6000, first activate the symbol for your acoustic leak
detection measuring operation in the main menu and confirm
your selection.
