3.2 Easyloc Tx transmitter Features The Easyloc Tx transmitter is distinguished by the following features: • Inductive coupling of the signal using the integrated antenna or transmitter clamp • Direct (galvanic) coupling of the signal using connected equipment (such as the measurement cable and power socket adapter) •...
Using the location system 4.1 Connection and initial use of the Easyloc Tx transmitter 4.1.1 Transmitter signals and modes of operation Signal characteristics The type and strength of the output signal can be configured by the user as follows to meet the specific requirements of either the line to be located or the site to be surveyed: Symbol Signal type...
4.1.2 Options for direct and inductive signal coupling 4.1.2.1 Direct coupling on cables and pipes Introduction Direct galvanic coupling is practical for cables which are easily accessible and free of current. The method of connection is dependent upon the position and nature of the lines (e.g.
Page 16
Principles of direct coupling The following table explains various basic principles of direct galvanic coupling: Application Principle of coupling Single-wire lines or pipes (with or without insulation against earthing) The distance between the earth spike and the ends of the connected lines should be as great as possible.
In doing so, it is not necessary to disconnect the lines. Megger offers a ready made house connection set for this type of coupling (also see section 3 System overview, page 3-10).
4.1.2.3 Inductive signal coupling Inductive signal coupling For lines which are not easily accessible, the signal from the transmitter has to be inductively coupled via the integrated antenna. The inductive coupling of the signal is highly recommended if unknown lines are to be located (e.g.
Both the FlexSonde GOK50-R and an active probe are available as accessories for the Easyloc RxTx location system (see section System overview, page 3-10). When locating non-metallic pipes, the following guidelines should be observed: •...
4.1.3 Initial use of the transmitter How to proceed Follow the steps listed below in order to prepare the transmitter to search for lines in conjunction with the receiver: Step Action Connect the transmitter to the line to be located using the most suitable method, or place the transmitter on the site to be searched (see section 4.1.2 Options for direct and inductive signal coupling).
4.2 Locating lines with the Easyloc Rx receiver 4.2.1 Changing the system settings 4.2.1.1 Depth measurement settings (not available for Easyloc Basic) Proceed as follows to change the settings: Step Action Press and hold the button. Briefly press the button while continuing to hold down the button until an audible signal is heard.
4.2.1.2 Changing the receiving frequency Proceed as follows to change the receiving frequency of operation modes with more than one possible frequency: Step Action Select the operation mode in which you want to change the frequency by pressing the button while the receiver is switched on. Switch the receiver off.
4.2.2 The basics of locating lines with the receiver 4.2.2.1 Modes of operation for the receiver Basics of passive line If a Easyloc Tx transmitter is not available, a site can also be probed by means of location passive line location. The Easyloc Rx receiver is capable of detecting radio signals in the frequency range between 15 kHz to 23 kHz as well as power signals in the frequency range between 50 / 60 Hz.
4.2.2.2 Regulating the sensitivity level to match the reception signal strength Display of reception Reception signal strength and sensitivity are shown in the following segments of the signal strength and display: sensitivity Segment Mode of operation Reception signal display bargraph The strength of the reception signal is represented by this bargraph scale.
4.2.2.3 Handling the receiver and locating the line Basics for handling the In order to be able to determine the position and orientation of a metallic conductor, receiver the following rules should be internalised and applied when locating lines. As shown in the following illustration, the receiver should always be held in front of the body in an upright position and as close to the ground as possible.
4.2.3 General site surveying Requirement A general site probing urgently needs to be conducted and there is inaccurate or no information available as to the location and orientation of metallic conductors on a site planned for construction (e.g. excavation work). Basics of site surveying When a site is to be searched for unknown conductors, a systematic approach should be taken.
4.2.4 Determining the direction of a line How to proceed Follow the steps below to determine the orientation of a metallic conductor: Step Action If the direction of the conductor will be determined with the aid of the Easyloc Tx transmitter, couple the transmitter's signal onto the metallic conductor in such a way that there is as little signal loss as possible (see section 4.1.2 Options for direct and inductive signal coupling) and switch on the transmitter (see section 4.1.3 Initial use of the transmitter).
4.2.5 Determining the depth of a line (not available for Easyloc Basic) Preconditions for The Easyloc Rx receiver has an automatic pushbutton depth measurement feature. automatic depth One precondition is that a clear signal from the Easyloc Tx transmitter is coupled onto measurement the conductor to be measured.

How to proceed Follow the steps below to determine the depth of a metallic conductor: Step Action If the depth of the conductor will be determined with the aid of the Easyloc Tx transmitter, couple the transmitter's signal onto the metallic conductor in such a way that there is as little signal loss as possible (see section 4.1.2 Options for direct and inductive signal coupling) and switch on the transmitter (see section 4.1.3 Initial use of the transmitter).

Step Action Mark this spot, then move in the opposite direction to the other side of the line until the symbol appears in the display again. Mark this spot as well, then measure the distance between the two spots. Result: Half the distance between the two spots corresponds approximately to the depth of the line.
4.2.6 Masking-Out Lines Masking-out lines Under certain circumstances lines at lower depths can 'hide' deeper, adjacent lines, thus making it more difficult to locate them. In such cases, the transmission characteristics of the Easyloc Tx transmitter can be fully utilised and the lines which have already been located can be masked out. Line with weaker Line with good inductive coupling...
4.2.7 Functional test of the receiver Introduction If problems or strange measuring results occur during a line location procedure, it may be helpful to check the functionality of the receiver using the integrated self- test. This test may provide information about possible malfunctions of the instrument.

Error codes Error code Description Unimplemented frequency Not enough battery power for the self-test procedure Interferences too strong for the self-test 210 (operation mode POWER GRID) procedure 211 (operation mode 2) 212 (operation mode 3) In this case, the self-test should be 213 (operation mode 4) repeated in an environment with less interferences.
Maintenance Changing the batteries in The status of the receiver's batteries is checked upon start-up and indicated in the the receiver display. The system regularly checks the battery strength as well. If battery capacity falls below 10 % of the threshold value, an audible warning signal is given and the current status of the batteries is shown in the upper part of the display.
