1.1 Use

The radio transmitter RT 03 serves to receive the noise coming from fittings and to transmit it by radio to the correlator which is also delivered (! see the appropriate Operating Instructions).

1.2 System components

To make the transmitter ready for use, the following components are necessary:
antenna,
headphones (delivered with the correlator),
piezoelectric microphone,
adapters (for attachment to hydrants
and sliding valves) or
horseshoe magnet (for fastening on
metallic pipes without fittings).

Page 10

2.0 The Control of the RT 03

2.1 Switching on the device

The start up procedure of the RT 03 is the following:
" connect the piezoelectric microphone with the microphone
socket (pos. 5),
" screw the appropriate adapter (square adapter or
horseshoe magnet) to the microphone,
" attach the microphone to the fitting or the pipe, " connect the antenna (pos. 9) and " switch-on the device (pos. 1).
##
# Do not switch-on the device without antenna !
##
Immediately after the switching on of the device, the automatic level adjustment is carried out for about 6 secounds. During this
time you should avoid to make noise (taps, voices or the like). The number of bar segments on the bar chart shows the number of operating hours still available.
The RT 03 now is transmitting and permanently signals the relation between the actual and the adjusted level.
##
#
##
By means of the headphones (pos. 8), you can listen to the noise coming from the fitting. Now , all adjustments of the transmitter having been made, you can begin with the correlation.

2.2 Operating modes

T o change the operating mode, the „Turn down“ button (pos. 3) and the „Turn up“ button (pos. 4) are to be pressed at the same time.
Y ou can select between the three possible operating modes by actuating the „Turn down“ (pos. 3) or the „T urn up“ button (pos. 4):
For a moment, the display will indicate that now an adjustment operation is executed.
Automatic level adjustment
!normal adjustment when switching on the transmitter and for correlation;
By actuating the level button (pos. 2), this adjustment can be repeated at any time. This is recommended when e.g. the environment noises were too loud during the first automatic level adjustment.
Manual level adjustment
! operating mode for the sonic speed measurement;
During transmission the level button (pos.2) is locked; now the level is adjusted by the "Turn down" button (pos. 3) or the "Turn up" button (pos. 4) and can be controlled with the headphones.
Radio module switched off
!operating mode for the electro-acoustic water leak detection;
For this you will need an appropriate ground microphone or a test rod. This adjustment is announced by the regular blinking of the LCD display. With the level button (pos. 2) the headphones can be switched on or off.
The desired adjustment is acknowledged by activating the level button (pos. 2).

2.3 Adjustment of the headphone volume

The desired headphone volume can be adjusted by means of the „Turn down“ button (pos. 3) or the „Turn up“ button (pos. 4).
This is displayed by a „migrating gap“ within the segment range of 8 bars.
In this connection: Gap on the left means - headphone volume at „0“, Gap at right means - volume at maximum.
After switching off the transmitter the finally adjusted headphone volume will be preserved.

2.4 The Filter selection

With the rotating switch the following is beeing chosen: "ØHz" high pass, every noise portion is being amplified and
transmitted.
"160 Hz" high pass, only noise portions above 160 Hz are
being transmitted.
The optimum setting depends on a particular situation and has to be tried out. With the position "160 Hz" interfering noises within the deep frequencey range can (i.e.) be surpressed effectively. The position 0 Hz should be tried out amplified when using the hydrophone.
Basically the same filter position should be used for the radio transmitter 1 and 2.
10
Page 13

2.5 Function control

It is recommended to control the functioning of the transmitter by regular intervals. For this, switch-off the device and activate simultaneously the ON/OFF button (pos. 1) and the level button (pos. 2).
Afterwards the automatic level adjustment is carried out and the device is transmitting.
Follows a bar segment check by the LCD display, and
the display of the number of the software version.

3.0 Charging

During operating mode, the loading position of the RT 03 is constantly being displayed by segments.
If the RT 03 has not been charged for a substantial time, the remaining operation period decreases by way of self-discharging. Under these circumstances, the remaining operation time indicated can be higher than the time actually still available.
The number of segments displayed indicate the remaining hours of operation.
If the battery symbol is displayed during normal operation time, the accu­voltage has fallen so much that the remaining operation time stands aprox. by 15 min.
In case the accu-voltage is falling further , the RT 03 automatically switches off.
The transmitter can either be recharged by the plug power device, delivered with the RT 03 (230V/12V=) or by the car connection adapter (12V=/12V= or 24V/=12V=) respectively. Hereby the transmitter - in switched-off position - is connected via its charging socket with the chosen loading adapter. After a short acustic signal the following message is displayed:
e.g. 16 Hrs. charging time are still required before the battery is recharged fully. (In this instance the remaining operating time is 2 Hrs).
After that time the transmitter is fully charged and changes automatically into the buffer operation, thus covering the self discharging loss. The transmitter is ready for continued use, the accu is not sustaining any damage.
12
Page 15
Once the RT 03 has been recharged, the charging time is no longer displayed. The available operating time will be at least 10 Hrs.
In case the accu has been almoast completely discharged thus making a further operation impossible, it can also be worked via external 12V= instead of recharging: connect the transmitter to a 12V and actuate the on/off key.
While charging heat is developing within the instrument.

When charging in increased outside temperatures (i.e. during summer or inside the vehicle) please open the case.
There will be a 16 hour charging cycle with each new power supply . T o obtain the max. accu level, a new charging cycle should only be startet once the accu has been discharged.

5.0 T echnical hints

The radio transmitter RT 03 corresponds to the legal prescriptions relating to radio technical installations. Its transmitting power is suf­ficient for the transmission of signals over a distance of about 1,000 m. In that case the transmitting and the receiving antenna are in direct visual contact.
The range is reduced if the transmitter or the receiver are in metal­cased places (e.g. in a car or a metal-armored cellar). Nevertheless a reliable measuring situation can be established, if necessary , by means of the extension of the microphone cable.
T o ensure a better handling, the radio transmitter can be operated from a case which is delivered with the device. The connections for aerial, microphone and loading adapter are outside of it. Should water or humidity have penetrated into it, the device is to be stored with opened case.
