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).

3.3 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.

3.5 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.

4.1.5 Volume display

The speaker symbol indicates

that the A 100 headphones are
activated.

The volume display indicates

the volume set. If the bar on the
extreme left is shown in reverse
video, the volume is low; if the
bar on the extreme right is shown
in reverse video, the volume is
maximum.

The volume can be adjusted with

the cursor keys.

4.1.6 Battery symbol

The battery symbol appears
about 15 minutes before the

battery runs out. In case the ac­cumulator volume drops further,
the instrument automatically
switches off to protect the ac­cumulator.

4.1.7 Comment line

4.1.8 Basicamplication

4 Water leak detection

Various possible settings and

parameters are displayed in the

comment line. The lter setting is

shown here, for example.

Basic amplication is useful for

adapting to extreme situations.
The higher the basic amplica­tion, the louder the noise in the

headphones. The values 10, 100
or 1000 appear in the display.

Basic amplication can be al-

tered with the magnifying-glass

key (see section 4.2.6).

4 Water leak detection

Modus „MAX“

4.2.2 Gauntlet key

If you hold down the micro key
for 3 seconds, you can switch to

„MAX“mode. This mode helps

with acoustic line detection. In­stead of minimum values, only
max values are shown in this

mode (only with microphones

with cable connection, not with

radio microphones).

Pressing the gauntlet key acti­vates the A 100. Depending on
the options selected in the set-up
menu it is deactivated either by
releasing the gauntlet key or by
pressing it again.

4.2.3 Hz key

12

The Hz key is used to alter the
frequency-lter setting. The l-

ter bandpass - which is a least

300 Hz wide - can be set any­where between 1 Hz and 10 kHz.

Pressing both cursor keys at
once resets the bandpass to its
default setting, which depends
on the probe.

Different leak noises can be

heard best in different frequency
ranges, and two people may
hear the same noise differently.

To optimise acoustic perception

a bandpass can be set.In this
case only a particular frequency
range is fed to the headphones.

The best setting can be found

by experiment, or alternatively
the A 100 can search for it au­tomatically.

Setting the frequency range manually

z Press the Hz key.

The most recently set limits
are displayed; the lower lter
limit ashes.

z The cursor keys change the

lower lter limit step by step.

z Press the Hz key again.

The upper lter limit ashes.

z The cursor keys change the

upper lter limit step by step.

z Press the Hz key again.

The lter limits are saved.

4 Water leak detection

4 Water leak detection

Automatic search for the best frequency range

The A 100 has a lter-optimisation function that automatically

searches for the best frequency range. It should not be activated

if there is any signicant extraneous noise, and the leak noise -

particularly ground-borne noise - should already be audible.

4.2.4 Cursor keys

z Press the Hz key until a clear-

ance tone sounds.

z The A 100 takes a „noise sam-

ple“ and analyses it.

While analysis is under way

the display indicates various

frequency ranges. The noise
produced by the lter values

displayed can be heard over
the headphones.

z The A 100 selects the fre-

quency range in which the leak
noise is especially clear.

The cursor keys are used to ad­just the volume of the speaker or

headphones. The volume setting

is shown in the display by a bar
in reverse video.

4.2.5 Light key

14

The light key switches the dis-

play illumination on and off.

It switches off automatically after

about 2 minutes.

4.2.6 Magnifying-glass and on/off key

The analog display indicates
the relative noise level. The

display can be adapted to pre­vailing conditions to make a
change in the display from one
measurement point to another
easier to detect. This adapta­tion switches the analog display

(instantaneous value) between
scale values 10, 100 and 1000

and alters basic amplication for
the headphones.

10 = high sensitivity, high

100 = medium sensitivity,

1000 = low sensitivity, low

Automatic adjustment takes

place to maintain the ratio be­tween the current delayed-action
value and the instantaneous
value.

4.3 Probe overview

4.3.1 Ground microphone BO-4

4.3.2 Ground microphone 3P-4

The ground microphone BO-4

is used to locate leaks beneath
stabilised surfaces.

The ground microphone 3P-4

is used to locate leaks beneath

unstabilised surfaces. An earth

spike can be screwed onto it
for use in soft ground. Its 3 feet
guarantee stability at all times.

4.3.3 Carrying rod H-4

18

for ground microphone or

for other microphone types.

z To switch off, unplug the probe

from socket 1.

4.5 Sound-protection function

Caution!

Only Sewerin headphones should be used, as these
are adjusted to the A 100. The threshold at which
the sound-protection function is triggered can be

adjusted: see section 4.8 „Individual adjustments“.

4 Water leak detection

The A 100 incorporates a sound-
protection function. With a sud-

den loud noise the sound in
the headphones is immediately

mufed. If the sound gets even

louder the headphones are
switched off. Once this noise
source has ceased the A 100
reverts to normal operation.

The sound-protection function

ensures that no excessive sound
pressure reaches the ears.

This headphones symbol ap­pears in the comment line when
the sound-protection function is
activated.

4.6 Preliminary location

Structure-borne sound is trans­mitted a very long way by metal­lic pipes, which makes the test
rod very effective for preliminary
location.

z Connect the headphones to

the A 100.

z Connect the test rod to the

A 100.

z Place test rod on the rst mea-

surement point.

19

4 Water leak detection

z Activate the A 100 with the

gauntlet key or the micro­phone key.

A speaker symbol appears
in the display during mea­surement.

The analog display indicates

the current measurement
volume.

The noise can be heard by the

headphones.

During this measurement the

digital display indicates the
smallest value measured.
The small digital display in­dicates the smallest value
measured during the previous

measurement. (This value is 0
after rst measuring.)
The smallest measured value

is shown in the analog display
in reverse video during the
measurement.

z To deactivate the A 100 re-

lease the gauntlet key or press
the microphone key again.
If the A 100 is not deacti­vated when the gauntlet key
is released, the function of
the gauntlet key has been

changed (see section 4.8). In

this event press the gauntlet
key again.

z Place the test rod on the

next measurement point and
proceed exactly as described
above.

The previously measured

value now appears in the small
digital display for the purposes
of comparison.

20

4 Water leak detection

In water leak detection the display will be similar to that shown
in the illustration above.

The noise is loudest near the leak and quieter further away.

On the left: the analog display indicates about 30%: this is the
instantaneous noise value.

However, the analog display often uctuates substantially because
of changing ambient noise. Even a trend can be hard to recog-

nise. This is why the large digital display (gure 16) indicates the

smallest noise value measured at this point so far (the current
delayed-action value). Even if ambient noise grows louder, this

display is unaffected - while if it grows quieter the display falls
further.

The gure 16 is also shown in the analog display as a segment

in reverse video.

The small digital display indicates “0”: as yet there is no value

in memory.

Centre: the analog display indicates about 60%. The large digital
display (gure 38) indicates a value greater than the left-hand
measurement point. This is an indication that the leak is closer.

The small digital display now indicates “16”: it reminds you of

the result from the last measurement point (last delayed-action
value). This makes it easier to decide whether you have not yet

reached the leak or have already gone past it.

21

4 Water leak detection

Right: the current delayed-action value has fallen because the

leak is further away. The last delayed-action value, “38”, provides

us a further comparison.

The following illustration shows how a leak noise overlaid by
uctuating extraneous noise is shown in the display.

22

4.7 Pin pointing

Non-metallic pipe materials do not transmit structure-borne sound

as well. Therefore checking at the valves is not enough. The

sections between valves must also be checked with a ground
microphone.

Listening to the surface of the ground at short intervals enables the

leak to be located without digging. Here, too, the A 100 provides
a precise optical comparison of the noise intensities.

The above illustration, for example, shows how the display

changes when passing a leak.

4 Water leak detection

z Connect the ground micro-

phone to the A 100.

z Place the microphone on the

ground.

z Activate the A 100 with the

gauntlet key or the micro­phone key.

A speaker symbol appears

in the display during mea­surement.

The analog display indicates

the current measurement
volume.

23

4 Water leak detection

The current noise can be heard

through the headphones.

The digital display indicates

the smallest value measured.

The small digital display in­dicates the previously-meas-

ured value. For the rst mea­surement this value is 0.

The smallest measured value

is shown in the analog display
in reverse video.

z To deactivate the A 100 re-

lease the gauntlet key or press
the microphone key again.

If the A 100 is not deacti­vated when the gauntlet key
is released, the function of
the gauntlet key has been

changed (see section 4.8). In

this event press the gauntlet
key again.

z Place the ground microphone

on the next measurement
point and proceed exactly as
described above.

The previously measured

value now appears in the small
digital display for the purposes
of comparison.

z Use the ground microphone

to check the area of the sec­tion where the leak is thought
to be.

The illustration on the previous

page shows an example of the
display when crossing a leak.

24

4.8 Individual settings

On the A 100 various settings can be freely selected and perma-

nently saved. The set-up table on the next page highlights the
various possibilities.

This is a list of settings that you can alter and save. First of all

please switch-on the instrument.

4 Water leak detection

z Hold down the microphone

key.

z Press the on/off key.

„ELWset“ appears in the com­ment line.

z The microphone key calls the

menu items one after another.

z The cursor-up key alters the

status of the selected menu.

z After the last menu the „save“

message appears.

z The cursor-up key saves the

current settings and termi­nates the function.

Notes:

The ear protection function should be set to „low

level“ only with low surrounding noise so that is
already activated with moderate noise levels. In
situations with high noise, such level should be set

to option (1), factory settings. In special cases, the
setting option (2) may be used. The ear protection

function will then only be activated in case of very

loud noise levels. To avoid that the ear protection
function is activatet too often and impairs locat-
ing the leak, the headphones’ volume may not
be set too loud.
