HIGH LOW sound change Mark the places with the highest tones for further pinpointing later 15 For Full Coverage Re locate the 800 H transmitter at least once several steps to the right or left in order to provide complete coverage This is because any conductor which is directly underneath the transmit ter will not be detected Pinpoint and Determine Signal Source As with normal Inductive Locating place the 800 H transmitter upright on one of the marks made earlier in line with the sus pected run of the conductor Pinpoint the conductor on the other side of the search area in the normal manner as described on page 11 After pinpointing the conductor raise the receiver toward the transmitter to be sure the signal is mostly coming from the con ductor and not through the air as described on page 13 Repeat this process for each of the HIGH pitch areas found ear lier and mark the lines accordingly SEARCH AND SWEEP Generally two people can perform a search over a broad area quicker than one person Set Up the Search Start over an area where there are no conductors One person holds the transmitter to his her side in line with the suspected run of the conductor s The other person stands 8 10 steps away from the transmitter holding the receiver to his her side Be sure the receiver is set to receive High frequency page 8 Turn both units ON and keep them pointed at each other Set the receivers sensitivi2.

Trace as far as necessary adjusting the sensitivity control to maintain a solid non beeping tone Weak or Confusing Signal When the sensitivity control is fully clock wise or the tone be comes jittery or unclear reposition the transmitter at the last clear location and continue tracing SEARCH AND SWEEP One Person This technique is beneficial in finding conductors with unknown locations and with no access points Basically you use the equipment in a way that scans the entire ground to find all con ductors in a specific area Please read the instructions for induc tive locating before proceeding Position the Transmitter Lay the 800 H Transmitter on its side as shown below This will flood the area with signal Turn ON the Transmitter Set up with the receiver the same as you would during inductive locating Move 5 10 feet from the transmitter face the transmit ter with the antenna near the ground and turn the receiver ON Set the sensitivity control so that the meter reads 4 and you hear a LOW pitched tone Locate the Conductor s With the receiver facing the transmitter walk in a circle around the transmitter Keep a steady distance from the transmitter and from the ground Listen for the HIGH pitch tone areas DO NOT adjust the sensitivity After locating the HIGH pitch areas go back and pin point the conductors in those areas You may need to re adjust the sensitivity at this step looking for the LOW
4. 800 H Transmitter produces an audible tone when the unit is ON When the tone is a high pitch then a good signal is being put out If during Conductive mode a low pitch is heard then there is poor signal being placed on the conductor This could be due to a bad ground or poor connection to the pipe etc If the Transmitter starts beeping then the batteries are getting low Receiver The receiver can be used during all modes described above Signal response feedback is given by an audio speaker and a meter Receiver Continued To turn the 800 H receiver ON simply turn the sensitivity knob until it clicks The higher the number on the knob the more sensitive the re ceiver is oom OF Maximum Higher No More sensitivity A d Gain Both the audio speaker and the meter let you know when the receiver is over a conductor When the needle on the meter reaches 10 it is at peak signal Beyond 10 the signal becomes saturated and you need to lower the sensitivity To save battery life the Receiver turns itself OFF after 5 minutes of no use To reset the Receiver and turn it back ON simply turn the switch OFF and back ON The sound the receiver makes is as follows High Pitch close to conductor Low Pitch moving away from conductor Beeping sensitivity is too high High Pich Low Pitch HE SIGNAL At any given distance say 2 feet at any direction from the con ductor the strength of the si

7. arrying Case Advantages of the 800 H Every locating job is different Success calls for a unique blend of equipment experience and persistence In some situations a low frequency conductive locator will perform better than a high frequency inductive locator In other situations the reverse is true The advantage of the high frequency is that it traces poor con ductors can locate short lengths better than the low frequency and it does not have to be directly connected though this method is available Inductive operation is much faster and eas ier allowing the operator to move the signal to any place which is useful The disadvantage of high frequency during inductive locating is that it can place more signal on adjacent conductors making isolation more difficult The 800 H is capable of both inductive and conductive modes During conductive mode the high frequency no longer induces signal which helps isolate the target The receiver has a meter to show signal strength which is helpful in noisy situations This meter also aids in depth estimation We have also tuned the receiver s audio feedback to produce tones that are most audible by the human ear In short the Series 800 H Professional Pipe amp Cable Locator is a more complete and productive tool for any user SAFETY FIRST DANGER Shock Hazard Connecting directly to any con ductor can be hazardous and result in electric shock injury or death Only licensed or
