4. Fluke company confidential Underground Cable / Pipe Locator Systems The AT-3500 is an economical, simple and rugged solution to utility locating, great for parking lot and airport lighting applications Model:AT-3500SC-3500MLS55-3 MSRP:$2,499$399$499 Target audience/application : Electrical contractors, locate companies, Electric and Telco utilities Single active frequency instrument employs the proven 33 kHz frequency for most locating applications highly sensitive power and radio modes for line avoidance at utility construction sites Depth measurement with the press of a button in all modes of operation (active and passive). Locates underground energized and de-energized wires, cables and pipes Three testing modes for best accuracy – –Passive Power (50 / 60 Hz) –Passive Radio (RF) –Active T-3500 signal generator with induction mode or directly connected to the cable with test leads or optional clamp Active Mode Depth measurement up to 16’ (4.9m) Semi-automatic gain control – fast signal location and control 33 kHz active frequency – best frequency for general locating Full featured transmitter – quality locating capability Precise pinpointing of buried services and exceptionally fast sound and meter response with backlight multiple-segment bar-graph digital display and audible indicators Rugged durable construction, weatherproof and drop resistant up to 5’

5. Fluke company confidential AT-5000 / AT-5005 are faster and more accurate to what’s available on the market today. The AT-5005 features A- Frame attachment to pinpoint cable ground faults in non- destructive way. Professional Underground Cable / Pipe Locators Distance sensitive Left / Right indication guides the user to the exact location of the buried utilities which saves time and effort not available on standard locators The Signal Select and Distortion Alert provide superior accuracy by visually indicating a clean signal of the traced line, versus “ghost” and ‘return’ path of false signals coming from the neighboring lines, and keeping the user on the target line. The core of the AT-5000 / AT-5005 Utility Locating Systems is the ergonomically designed handheld receiver. Designed for comfort, the lightweight receiver is balanced for all day use. The receiver’s bright color display is complete with intuitive, easily read graphics that can be viewed in all lighting conditions. Target audience/application : Electrical contractors, locate companies, Electric and Telco utilities

6. Fluke Corporation company confidentialJanuary-February 2010 Locators Passive Mode – 50/60Hz Signals Preferred method to demonstrate Locators No Transmitter necessary, the receiver will locate all energized wires

7. Fluke Corporation company confidentialJanuary-February 2010 Locators Passive Mode – Radio Signals The same principles as with 50/60Hz method but the signal is created by surrounding radio waves generated by cell towers and radio stations. 50/60Hz method is easier to demo, since Radio Waves are more difficult to explain to the customer.

8. Fluke Corporation company confidentialJanuary-February 2010 Locators Active Mode – Inductive Second preferred method to demo Locators A Transmitter does not need a physical connection with traced object The transmitter will “energize” all surrounding metal objects with signal This method is used mainly to mark all buried metal utilities Applications: Excavation, General marking of underground utilities

9. Fluke Corporation company confidentialJanuary-February 2010 Locators Active Mode – Direct Connection More difficult to demo, transmitter needs to be connected to the bare metal of the utility (access problem) Method used to locate particular buried utility Application: –Wire / Pipe troubleshooting (shorts, opens, breaks) –Locating particular utility in order to find connections or junction boxes

10. Fluke Corporation company confidentialJanuary-February 2010 Tracing Methods –Active (requires transmitter) – With energized lines Locating open wires AT-5000 display shows Left / Right arrow Indication –Passive (does not requite the use of the transmitter) – Detecting 50 / 60 Hz lines carrying current Using radio frequency to detect a signal AT-5000 Receiver Display shows signal strength (Left / Right arrow indication is not available for passive tracing)

12. Fluke Corporation company confidentialJanuary-February 2010 Tracing Lines In passive mode receiver display will switch to passive mode (signal strength indication) Position of the received should be perpendicular to the traced wire

13. Fluke Corporation company confidentialJanuary-February 2010 Active Mode Tracing - Setting Up The Transmitter Press yellow ON/OFF button. If necessary press frequency button to change frequency (7) Locate the transmitter on the ground over the utility you are going to trace (no direct connection is necessary) ➊ Direct Connection ➋ Audio Volume ➌ Battery Status ➍ Signal Select ➎ Constant Power ➏ Active Frequency Menu ➐ Frequency in use ➑ Power output in use ➒ Power output level ➓ Resistance output level

15. Fluke Corporation company confidentialJanuary-February 2010 Amprobe differentiation - Guidance Compass The guidance compass indicator provides additional information about the cable you are tracing: –The direction of the signal is indicated by the orientation of the orange arrow inside the guidance compass indicator –A forward pointing arrow indicates that the receiver detects a signal flowing away from the transmitter. A downward pointing arrow means that the signal is a return signal flowing back towards the transmitter. Changes in the direction of the line relative to the orientation of the receiver are indicated by the signal direction arrow moving away from the North or South position The presence of bleed over signals is indicated by the RED color filling the inside of the guidance compass indicator.

16. Fluke Corporation company confidentialJanuary-February 2010 Amprobe differentiation – Signal Direction The direction of the signal in the targeted line is determined by analyzing the sign of the demodulated Signal Select signal. When the R-5000 receiver is positioned over a signal that carries an inverted field (i.e., one in which the phase is –180° from the expected, the Guidance Compass points down, as shown below for a line that is bonded to the target line and carries return current.

17. Fluke Corporation company confidentialJanuary-February 2010 Amprobe Differentiation – Left / Right Indication The Left/Right display is tremendously useful in refining the precise location of the target line. The vertical black bar represents the underground utility cable. Follow the vertical bar to determine the position of the cable. When shown at centerline it indicates that the R-5000 Receiver is on top of the target.
