Page 28: Determining The Depth Of A Line
4.2.5 Determining the depth of a line Preconditions for The Easyloc Standard Rx receiver has an automatic pushbutton depth measurement automatic depth feature. One precondition is that a clear signal from the Easyloc Standard Tx measurement transmitter is coupled onto the conductor to be measured. For this procedure, the transmitter's signal has to be continuous (not pulsed) (see section 4.1.1 Transmitter signals and modes of operation). - Page 29 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 Standard 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...
- Page 30 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.

Page 31: Masking-Out Lines
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 Standard Tx transmitter can be fully utilized and the lines which have already been located can be masked out. -
Page 32: Functional Test Of The Receiver
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. Preferably, the self-test should be performed in an interference-free environment without live cables. - Page 33 Error codes Error code Description Unimplemented frequency Not enough battery power for the self-test procedure 210 (operation mode POWER GRID) Interferences too strong for the self-test 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.

Page 34: Maintenance
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. - Page 35 Changing the floor cap on The plastic floor cap, which prevents the tip of the receiver from being damaged, can the receiver be easily replaced with the aid of a pointed object (e.g. screw driver). Replacements can be ordered through the Megger sales team.
