![]() ![]() Follow the line of the buried conductor, marking it as required across the area to be excavated.Īn initial sweep using Avoidance Mode is recommended, followed by detailed scans using the other modes. Trace the buried conductor keeping the C.A.T4 vertical and moving it steadily from side to side. (This process can be less precise in Power Mode because of the nature of detectable power signals). Check for accuracy by varying the sensitivity control while rotating the C.A.T. The C.A.T is at right angles across the cable or pipe when the bargraph and audio are at a maximum, and is directly inline with it when the bargraph and audio are at a minimum. Once a cable or pipe’s position has been pinpointed, rotate the C.A.T4 above it. If the position cannot be easily determined using Avoidance Mode, switch between the dedicated locate modes (Genny, Power or Radio) before adjusting the sensitivity control to pinpoint the cable or pipe.ĭetermining a cable or a pipe's direction The tidemark feature hold the maximum bargraph reading to ease identification of a peak readout. By repeating this process back and forth across the maximum readout position, the cable or pipe’s position can be pinpointed. In all locate modes the bargraph and sound levels increase as the C.A.T gets closer to a pipe or cable, and reduce once it passes beyond it or as it gets further away.Īs the bargraph readout passes maximum over a pipe or cable, turn the sensitivity control down and move back over the locate position. The sensitivity control should be set to maximum before beginning to locate. The sensitivity control is used to narrow the field in which the C.A.T4 can locate a pipe or cable. Swinging the C.A.T will affect locate accuracy all eC.A.T4 and gC.A.T4 models feature SWING, a sensing device to remind operators to use the C.A.T correctly. Do not swing the C.A.T4 or tilt it more than a few degrees from the vertical. Hold the C.A.T4 with the blade vertical and with the lower edge just above the ground. Radio Mode : detects radio signals originating from distant radio transmitters as they travel along underground pipes and cables. a street light cable during daylight hours). Power signals may not be found on power cables that are switched off (e.g. Some power cables DO NOT radiate detectable power signals. These signals may be found on any pipe or cable, not just power cables. Power Mode : detects signals originating from power transmission networks. The C.A.T4 and Genny4 feature new locate signals that make the combination more sensitive to small core cables (e.g. Using a Genny is the most reliable way to detect a pipe or cable. There are various ways of applying the Genny signal. ![]() Genny Mode : detects the locate signals produced by a Genny. The sensitivity control adjusts the Power, Radio and Genny signal levels simultaneously. ![]() If in doubt, contact the person responsible, or Radiodetection.Ĭ.A.T4 models are equipped with four locate modes:Īvoidance Mode : detects all locate signals simultaneously, including Genny, Power, and Radio signals. If flashes continually on startup, immediately return your C.A.T for service/calibration.ĭo not attempt to use a C.A.T4 for tracing pipes or cables outside its calibration period. When a service/calibration is due in 31 days or less, the screen will display 'CAL' at startup, followed by the number of days until a service/calibration is due.ĬALSafe enabled units are equipped with a system which does not permit them to function once they are beyond the expected service/calibration date. Refer to the C.A.T Manager manual for further information. If required eC.A.T4 and gC.A.T4 can automatically be disabled if an warning is detected. NOTE: The internal data logging system will not work properly if the message has been displayed. If a problem is detected the unit will momentarily display the message and sound a warning audio tone. ![]() Replace both batteries if there is no bleep or if the battery icon is flashing.ĮC.A.T4 and gC.A.T4 units perform a self test at startup to check for logging system errors. Press and hold the trigger and listen for the bleep indicating the batteries are OK. ![]()
