STRUCTURE TO BE TRACED THIS MAY INCLUDE ELEC TRIC LINES CABLES GAS LINES WATER LINES TRACER WIRES ETC Transmitter The most important element in properly locating a buried underground conduc tor is to properly energize the conductor This is the function of the transmitter Therefore the operator must understand the function of the transmitter in the system and learn which mode of operation is best for any given locating assign ment The majority of the problems an operator may encounter in the field can be traced back to improper use or incorrect positioning of the transmitter Before using the transmitter in any of the following applications it is essential that the operator determine if the transmitter battery has sufficient charge to complete the expected operation To test the battery simply turn the transmitter on and observe the percentage of batter charge on the display A key feature of the Sure Lock is its multi frequency capability A multi frequency transmitter is capable of transmitting a single frequency or multiple frequencies simultaneously Multiple frequency output is best used to initially select and verify which single frequency to use for a given locate Generally this is accomplished by first putting the transmitter in ALL OUT PUT mode and then stepping through the frequency which gives the adequate SPIs and good depth can generally then be selected on both the transmitter and receiver Multipl
