Routing Routing screen of the Sonel LKZ Mobile application Routing screen of the Sonel LKZ Mobile application is shown below. In the central part there is a com- pass with a route preview. 1 – received signal strength. 2 – graph of the received signal strength.
Page 21
In the upper and lower parts there are controls and settings icons described in sec. 3.5.2. There is a set of indications on the sides. h – depth of the routed object relative to the detector, expressed in meters. α – angle of deviation of the routed object relative to the detector axis, expressed in degrees.
Methods of signal reception The LKZ-2500 system can receive the signal in three different ways. Narrow. This characteristic is used to precisely determine the location of the signal and for accurate routing. When it is active, an algorithm determines whether the conditions for the correctness of the tracked signal are met ...
Place the LKD-2500 detector over the object to be traced. When you start getting closer to the object, you will notice an increase in the strength of the received signal on the bargraph and numerical indicator. When you are directly above an object or in its immediate vicinity, you will see a line on the screen showing its course.
5.3.3 Working in active mode – Signal Working in the Signalactive mode involves precise locating of objects capable of transmitting sig- nals. This means that such routing can take place over all active or inactive objects capable of carrying signals. In this mode using the LKN-2500 transmitterto force a signal in the object is necessary. 5.3.3.1 Methods of introducing a signal to the routed object ...
Page 25
Inductive method – involves introducing a signal to the object inductively using internal antenna of the transmitter. The device is placed over the object as directed by the arrow on the housing. The signal is induced in all objects located under the transmitter, so it will be possible to locate more objects located underground.

5.3.3.2 Introducing signal In the LKN-2500 set the method of introducing the signal (galvanic / clamp / inductive) to the routed object. Connect the signal forcing circuit. Select the shape and the frequency of the transmitted signal Set the signal strength. In the induction method, the signal strength is locked at the maxi- mum level.
