Question - How often should a function check be carried out on a CAT & Genny?
-
Answer - Every time the CAT & Genny is used
Surveying the area
-
Determines the location and extent of survey area
-
Always uses the CAT correctly to avoid the swing alert being activated
-
Surveys the area in avoidance mode 'A' to establish any underground plant
-
Surveys area in 'P' mode
-
Selects 'P' mode on CAT
-
Turns sensitivity switch to maximum
-
Uses the correct search pattern to sweep the area ensuring that the CAT remains in a vertical plane
-
Reduces the sensitivity switch to narrow the response
-
Rotates the CAT to define direction of underground plant
-
Traces the underground plant and clearly marks its position on the ground with the letter 'P'
-
Surveys area in 'R' mode
-
Selects 'R' Mode on CAT
-
Turns sensitivity switch to maximum
-
Uses the correct search pattern to sweep the area ensuring that the CAT remains in a vertical plane
-
Reduces the sensitivity switch to narrow the response
-
Rotates the CAT to define direction of underground plant
-
Traces the underground plant and clearly marks its position on the ground with the letter ‘R’
-
Surveys area in 'G' mode using the genny on direct connection
-
Selects ‘G' mode on CAT
-
Connects the red lead from the Genny to the appropriate street furniture / utility pipework
-
Connects the black lead to the earth spike at 90° to the line of the trace after checking that no <br>underground plant is present where the spike is to be located
-
Checks the connections by noting the change of tone from the Genny
-
Traces the underground plant and clearly marks its position on the ground with the letter ‘G’
-
Surveys the area using the signal clamp on above ground metallic pipe / cable (not lamppost)
-
Selects the ‘G' mode on CAT
-
Plugs the clamp into the Genny
-
Places the clamp around the pipe or cable ensuring the jaws are closed
-
Switches on the Genny
-
Opens and closes the jaws on the clamp and confirms a drop in the speaker tone when the jaws are <br>closed
-
Uses the correct search pattern to sweep the area ensuring that the CAT remains in a vertical plane
-
Traces the underground plant and clearly marks its position on the ground with the letter ‘G’
-
Survey the area in 'G' Mode using the CAT on induction
-
Selects ‘G' mode on CAT
-
Switches on the Genny
-
Places the Genny over the plant, 10 metres (paces) outside the search zone
-
Uses the correct search pattern to sweep the area ensuring that the CAT remains in a vertical plane
-
Reduces the sensitivity switch to narrow the response
-
Rotates the CAT to define direction of plant
-
Traces the underground plant and clearly marks its position on the ground with the letter ‘G’
-
Surveys using the live plug connector to trace cables within a building or to trace external electrical
supplies supplying the property -
Plugs the live plug connector into the Genny
-
Switches off the internal 3 pin socket indoors and plugs the live plug connector into the 3 pin socket
-
Turns on the Genny and switches on the internal 3 pin socket
-
Removes the strike and swing alert status
-
Traces the cable and clearly marks its position using an appropriate technique
-
Question - How would you be alerted to shallow underground plant?
-
Answer - A star (*) would appear in the window of the CAT and by an audible warning
-
Question - How many days are left when the screen first displays ‘CAL’ at the point of start-up and what will occur when ‘CALSAFE’ appears?
-
Answer - 31 days and the CAT will not be able to be used
-
Question - How would you eliminate adjacent cables or pipes on induction mode and what is this method known as?
-
Answer - By placing the Genny on its side which is known as ‘nulling out’
-
Question - How can you improve the signal strength when using direct connection and clamp modes?
-
Answer - By using the boost button on the Genny
-
Question - How would you know if the CAT4 is being used in areas where very large power signals are present?
-
Answer - The signal bar graph will flash<br>
