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.
2.2 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 surround-
ing 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).

3.1 Switching on and off
zPlug a probe into the appropri-
ate input .
Probe connection: input 1
zA brief signal tone sounds.
zThe software version appears
in the display.
zThe charge status of the re-
chargeable batteries appears
in the display.
zThe type of probe plugged in
is automatically determined.
zThe probe type briey appears
in the display. If the probe type
is not automatically identied it
can be selected manually (see
section 3.1.1).
zIf a microphone has been
plugged in, the bandpass cur-
rently set for the frequency
lter is briey displayed.

3 Use
zThe layout of the display de-
pends on the used probe. The
measurement process may be
started.
zTo switch off, unplug the probe
from the input.
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:
zHold down the microphone
key.
zPlug 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.
zPressing the cursor keys
switches between possible
probes.
zPressing the magnifying-glass
key displays the selected
probe.
3.2 Adjusting the display contrast
The display contrast can be ad-
justed as follows:
zHold down the light key.
zPress the cursor-down key to
reduce the contrast.
zPress the cursor-up key to
increase the contrast.

3 Use
3.3 Charging equipment
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 fol-
lowing sockets on its side:
zAC/DC adapter M4,
100 – 240 V~
zVehicle cable M4 for 12 V
3.4 Charging
Note:
Charging the accumulator only within temperature
range 0 – 45 °C.
zSwitch off the instrument and
plug it into the docking station.
The following (or similar) ap-
pears in the display:
zThe 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 opera-
tion (light, volume ...) charging
time takes max. 4 hours.
zWhen it is fully charged all the
bars appear and the number
display disappears.

7
3 Use
zYou 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.
zConnect cable to the docking
station inside the case.
zConnect 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 op-
erating hours, and it must be recharged.

3 Use
3.5 Connecting the headphones
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:
zPlug the headphones jack-
plug into socket 2.
The speaker is switched off
automatically; sound is output
to the headphones.
zWhen the headphones are
unplugged the sound is once
more output to the speaker.

4.1 Displays
4.1.1 Analog display
The analog display indicates the
current reading.
4.1.2 Digital display
The digital display indicates the
smallest value measured during
a single measurement.
In the „MAX“ mode, the digital
display always shows the great-
est measured value. In „MAX“
mode you can switch by hold-
ing the micro key for 3 seconds
(only with microphones with
cable connection, not with radio
microphones).
4.1.3 Small digital display
For the purposes of comparison
the small digital display always
indicates the precedent value
measured.

4.1.4 Speaker symbol
The speaker symbol indicates
that the A 100 headphones are
activated.
4.1.5 Volume display
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 ac-
cumulator volume drops further,
the instrument automatically
switches off to protect the ac-
cumulator.

4.1.7 Comment line
Various possible settings and
parameters are displayed in the
comment line. The lter setting is
shown here, for example.
4.1.8 Basicamplication
Basic amplication is useful for
adapting to extreme situations.
The higher the basic amplica-
tion, 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).
10 = high noise amplica-
tion
100 = medium noise ampli-
cation
1000 = low noise amplica-
tion
4.2 Key functions
4.2.1 Microphone key
Pressing the microphone key
activates the A 100. Pressing it
again deactivates it.

12
4 Water leak detection
Modus „MAX“
If you hold down the micro key
for 3 seconds, you can switch to
„MAX“mode. This mode helps
with acoustic line detection. In-
stead of minimum values, only
max values are shown in this
mode (only with microphones
with cable connection, not with
radio microphones).
4.2.2 Gauntlet key
Pressing the gauntlet key acti-
vates 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
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 any-
where between 1 Hz and 10 kHz.
Pressing both cursor keys at
once resets the bandpass to its
default setting, which depends
on the probe.

13
4 Water leak detection
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 au-
tomatically.
Setting the frequency range manually
zPress the Hz key.
The most recently set limits
are displayed; the lower lter
limit ashes.
zThe cursor keys change the
lower lter limit step by step.
zPress the Hz key again.
The upper lter limit ashes.
zThe cursor keys change the
upper lter limit step by step.
zPress the Hz key again.
The lter limits are saved.
