General safety instructions for the use of the
SONAPHONE KRD
The SONAPHONE KRD corresponds to the state of the art and the
safety-relevant rules. The manufacturer did everything to guarantee a
safety working. The user have to ensure that the safe use is not
impaired. The appliance is work-examined and was delivered in a safe
to operate condition.
(1) It is only allowed to use or to connect the provided accessories with
SONAPHONE KRD: the headphone, the ultrasonic probes, the
temperature probes and the charger.
(2) It is only allowed to use the device by trained persons. Every user
who works with the device has to read this user manual at first.
(3) To avoid a device defect the SONAPHONE KRD has to be protected
against moisture.
(4) The device and all equipment can be cleaned with a damp cloth.
Aggressive detergents can attack the plastic coating and can interfere
with the mechanical stability of SONAPHONE KRD.
(5) The accumulator of the SONAPHONE KRD can be charged by the
attached charger. The main voltage and the frequency have to be the
same as given on the rating plate of the charger.
(6) It is not allowed to open the SONAPHONE KRD or the equipment or
to do repairs on your own. Only the manufacturer is allowed to do
repairs.
(7) The SONAPHONE KRD and the used probes are proper for a usage
at a temperature range of 0...40°C. The permissible storage
temperature range is about -10...50°C.
(8) Working with the device SONAPHONE KRD and the probes should
be clearly visible. Never work with the probes in areas with noninsulated voltage-carrying parts or without intervisibility in unknown
areas. If you locate ultrasonic signals on electrical installations, a
sufficient safety distance need to be kept to avoid electrical flash-overs.

(9) Application and handling of structure-borne sound sensors have to
be executed with sufficient carefulness so that nobody can get hurt by
the cone point of the tip. Use the tubular for the probe on the shoulderstrap of the leather bag if you carry the probe or when it is not in use.
(10) Also use the leather bag with shoulder-strap if you climb stairs, a
ladder, platforms and so on, to prevent an accident.
(11) The application of the SONAPHONE KRD
electromagnetic fields should be avoided.

and also not for damages of a third party caused by misuse of the
appliance.

Functional description
At many flow processes of gases, liquids and solids in pipelines and on
leakages, ultrasound arise from friction. These ultrasonic signals are
received with the SONAPHONE KRD and the intensity gets audible with
speaker or headphone. Simultaneously the level of the ultrasound will
be displayed on a LCD or a LED-scale, respectively.
Ultrasound can arise out of a multitude of processes for example at
leakages within compressed-air-, steam- and vacuum plants. The
device is particularly suitable for
• steam traps
• leaking valves, gate valves, shutoffs, traps in line systems
• roller bearing defects
• cavity on pumps and compressors
• flash-overs and corona discharges on electrical installations
With the help of SONAPHONE KRD, faults can exactly get located and
their size can get assessed.
By the use of a thermocouple type K it is possible to measure
temperatures in an operative range of 0…800°C with an accuracy of
±2%. The thermocouple measurement is based on a comparative
measuring procedure between the probe tip (hot junction) and the other
hand of the thermocouple wire (cold junction). In our case the cold
junction is the SONAPHONE K. Therefore it is necessary that the
temperature of the SONAPHONE K corresponds to the surrounding
temperature.
The checking device SONAPHONE K is a battery-supplied, mobile
hand-held instrument. For the acquisition of the ultrasound, different
probes can be used, which can be connected with a cable or directly to
the checking device. For the temperature measurements a
thermocouple temperature probe is available, which can be connected
with a cable or directly to the testing device.

Starting up
For switching on or off the device the ON/OFF-button has to be pressed.
After an operation time of 10 minutes the device switches off
automatically. If the detection is not finished at this moment the
SONAPHONE KRD has to be switched on again.
CAUTION!
To prevent hearing damages the volume knob has to be turned to
minimum (left stop) before switching on the device. After switching on
you can increase the volume until the leackage signal can be
determined.
The usage of the structure-borne sound sensor
The usage of the structure-borne sound sensor allows to detect internal
switch processes by noise level measurements at a steam trap.
Therefore the probe has to be pressed onto the body of it. In a Ball float
steam trap e.g. the SONAPHONE K detects internal ball movements,
which allows to characterize internal functional expiries.
The usage of temperature probe
The temperature sensor supports this assessment by measuring
relations between input, output and body temperature as a function of
steam pressure.
The volume can be controlled through the VOLUME knob, where the
position influences the intensity of the LED-scale.
Über die Taste MAX kann eine Maximalwerthaltung des
Ultraschallpegels ein- bzw. abgeschaltet werden. Diese Funktion
unterstützt die Suche nach der größten Ultraschallquelle.
Pressing the MAXTemp button the temperature measurement can be
selected.storage of the maximum value of ultrasound signals can be
turned on or off. This function allows the user to search for the
maximum of the ultrasound source. When this function is active, the
yellow LED is lightened.
When the surrounding light is not sufficient, the display screen lights on
automatically.

Charging the batteries
If the operating time of the SONAPHONE KRD runs out, you have to
recharge the internal batteries. This will be displayed by means of
flashing from the green operating mode display. To start charging, you
have to connect the plug of the charger (on the right side) with the
SONAPHONE KRD. After that you have to plug in the charger. The red
charging lamp lights up during charging. If the battery is completely
discharged it can take 9 hours for recharging. When the charging is
completed, the charging lamp goes off and the charger can be
unplugged.
An overcharging protection in the device prevents a device damage
caused by overcharging.
The stationary operation via the charger is also possible.
If the red LED sparkles during charging, the SONAPHONE KRD has a
defect and has to be sent to the manufacturer for a check.
To improve the life of the batteries, they has to be recharged only when
the batteries are completely discharged.
CAUTION!
For charging of the internal batterie only the provided charger is allowed
to use.

Structure-borne sound sensor
The structure-borne sound sensors are used to prove ultrasound on
solid bodies.
They have to be pressed onto the testing place by hand. Favourable
points are those, where within the stream trap flow transitions are
arising.
CAUTION!
Using the body sound probe pay attention to the general safety
instructions for the SONAPHONE K (9).
To aquire reproducible results, the pressure force and the direction have
to be constant.

Temperature Probes
The SONAPHONE K allows to measure temperatures in a range of
0°C - 800°C. Therefore a NiCr-Ni thermocouple temperature probe is
available, which was constructed particularly for measurements on
rough surfaces.
The temperature sensor can be connected to the SONAPHONE K or by
the handle with the extension cable.
For receiving good results it is the best to compare the temperatures
from the input and the output with each other.

Maintenance
The device SONAPHONE RDK, the probes and the accessories have a
solid device construction. Nevertheless, they have to be protected
against mechanical damages and heavy impact loads. It is only allowed
to use solventless detergents.
The integrated batteries have a lifetime of maximally 1000 charging and
discharging processes. For that reason they have to be completely
discharged and afterwards recharged in regular intervals. You can
discharge the accumulator for example by switching on the device
SONAPHONE KRD. The device should be switched on until the green
LED will begin to sparkle. Pay attention that the SONAPHONE KRD has
an integrated Auto-Power-Off-function which switches off the device
10 minutes after switching on. After that you have to recharge it with the
delivered charger until the red charging control light goes off (see
section "Charging the batteries“).
