2 Function description

2.1 Water leak detection

The A 100 is used in combination with various microphones (listed

in the „Accessories“ section) for the electro-acoustic detection of
water-leaks.

When a pressurised pipeline develops a leak, water ows through

it into the surrounding soil at high speed.

Consequence:

The pipeline material vibrates at the exit point. This vibration is

transmitted by the pipe, with the result that it can be picked up

even at remote contact points (valves and the like). This structure-

borne noise is rendered audible by the A 100.

The water jet - and the pipe, in the vicinity of the leak - also induce
vibration in the soil. This is transmitted to the surface, where it

can be picked up as ground-borne noise.

Even with electro-acoustic leak detection the human ear retains
its importance. Suitable practice enables noises of different types.
and tones to be compared, and leak noise distinguished from
extraneous, unrelated noise.

2 Function description

2.2 Acoustic pipeline location

Plastic lines cannot be located by the classical electromagnetic
method because they do not conduct electricity.

The acoustic method of pipeline location uses a different principle:

the lines transmit mechanical vibration better than the surround­ing earth. If suitable vibrations are applied to the line, they are
transmitted along its length and through the earth to its surface,
and can then be located there with an ground microphone and
receiver with headsets according to the water leak detection

principle. As with water leak detection, the line is in the place

where the greatest intensity is found. Fibrous-cement and metallic
pipes can also be located in this way.

If you wish to detect the lines acoustically, follow the operating

instructions for the vibration emitter (eg, COMBIPHON). Proceed
as with for water leak detection. The A 100 also offers an additional
mode to assist in detecting lines (see section 4.2.1).

3 Use

3 Use

3.1 Switching on and off

z Plug a probe into the appropri-

ate input .

Probe connection: input 1

z A brief signal tone sounds.

z The software version appears

in the display.

z The charge status of the re-

chargeable batteries appears
in the display.

z The type of probe plugged in

is automatically determined.

z The probe type briey appears

1

in the display. If the probe type

is not automatically identied it
can be selected manually (see
section 3.1.1).

z If a microphone has been

plugged in, the bandpass cur­rently set for the frequency

lter is briey displayed.

4

3.1.1 Manual probe selection

If the probe is not automatically identied (if it is an old model, for
example), it can be selected manually:

3 Use

z The layout of the display de-

pends on the used probe. The

measurement process may be
started.

z To switch off, unplug the probe

from the input.

z Hold down the microphone

key.

z Plug in the probe.The „>“

symbol appears on the left of
the bottom text line and the
name of the probe that can

be selected, e.g. „M01“ in the

middle.

z Pressing the cursor keys

switches between possible
probes.

z Pressing the magnifying-glass

key displays the selected
probe.

3.2 Adjusting the display contrast

The display contrast can be ad­justed as follows:

z Hold down the light key.

z Press the cursor-down key to

reduce the contrast.

z Press the cursor-up key to

increase the contrast.

3.3 Charging equipment

3.4 Charging

Note:

Charging the accumulator only within temperature

range 0 – 45 °C.

When fully charged the instru-

ments have a maximum ope-

rating time of approx. 12 hours.

To charge an instrument you need
the docking station HS 1,2 A (see
g.), which can be used either in

the workshop or in the emergency
vehicle .

The docking station has the fol­lowing sockets on its side:

z AC/DC adapter M4,

100 – 240 V~

z Vehicle cable M4 for 12 V

z Switch off the instrument and

plug it into the docking station.

The following (or similar) ap­pears in the display:

z The instrument now has 5 op-

erating hours (= 5 bars) left. It

will take another 3 hours to be
fully charged.

The actual operating time

depends on the accumulators’

condition (age ...) and opera­tion (light, volume ...) charging

time takes max. 4 hours.

z When it is fully charged all the

bars appear and the number
display disappears.

6

3 Use

z You can leave the instrument

in the docking station until you
need it again.

If you have a case for your
A 100, it can be charged inside.

z Connect cable to the docking

station inside the case.

z Connect the plug-in AC/DC

adapter M4 or vehicle cable
M4 to socket 2.

3.4.1 Self-discharge

If the instrument is not placed in the docking station HS 1,2 A when
switched off the NiMH-accumulator will self-discharge, which is

considered when displaying the remaining operating time.

After no more than 30 days the instrument will indicate zero op­erating hours, and it must be recharged.

3 Use

3.5 Connecting the headphones

1 2

A 100 are tted with a speaker
(1).

Such produces the conrmation
and alarm signals. There is,
furthermore, a specic tone for

pipeline location.

During water leak detection no
leak noise is emitted over the
speaker: headphones must be
used. Switching from speakers

to headphones:

z Plug the headphones jack-

plug into socket 2.

The speaker is switched off

automatically; sound is output
to the headphones.

z When the headphones are

unplugged the sound is once
more output to the speaker.
