(which is evident by the display message “Weak field” or ---). In these cir- cumstances, it is recommended to determine the depth of the utility with the -6dB method (see Sec- tion. 4.6.3.3). LKZ-1500-LITE ● LKZ-1500 – USER MANUAL... -
Page 34: Indirect 6 Db Test Method For Depth Measurement
Moving to the left and to the right of the utility axis, find the positions in which the readings will be 6 dB less (this means that the signal strength is two times less). The distance between these two points will be equal to double distance from the Receiver to the utility line axis. LKZ-1500-LITE ● LKZ-1500 – USER MANUAL... -
Page 35: Locating By The Utility Current
The first Kirchhoff’s law says that the total current inflowing in a junction is equal to the total outflowing current. You should note, however, that values of the current intensity near the branches will differ from the actual values. Accurate and true measurements may be performed within long-distance and uniform areas only. LKZ-1500-LITE ● LKZ-1500 – USER MANUAL... -
