pulseEKKO PRO TLF Transmitter 1 1-Overview Overview This manual describes how to use the pulseEKKO PRO Ground Penetrating Radar (GPR) system transmitter. System Assembly & Startup: Section 2 on page 3 discusses in detail the step by step procedure for assembling the pulseEKKO PRO system and connecting the transmitter to it. Troubleshooting: Section 3 on page 9 presents some simple steps the user should go through when the transmitter is not working as it should.
1-Overview pulseEKKO PRO TLF Transmitter 2
pulseEKKO PRO TLF Transmitter 2 2-System Assembly and Startup System Assembly and Startup The modular design of the pulseEKKO Pro GPR makes the system very flexible and readily fieldportable. There are four essential components to the radar system: the control or console unit, the transmitter assembly, the receiver assembly and the Digital Video Logger (DVL).
2-System Assembly and Startup pulseEKKO PRO TLF Transmitter quarter of a turn. DO NOT APPLY UNDUE FORCE. It is usually best to have all the screws properly aligned in their socket before tightening each one. d) Carefully place the electronic boxes down onto the mounting block such that both brass pins fully connect. Then use the 2 plastic draw latch connectors to hold the electronics boxes on the mounting block.
pulseEKKO PRO TLF Transmitter 2-System Assembly and Startup b) Plug the black end of the single fiber optics cable (or dual fiber optics cable if you are using a remote trigger or odometer; see below) into the INPUT (black) connector in the transmitter and the other end into the single red receptacle labelled “Transmitter” on the console.
2-System Assembly and Startup 2.3 pulseEKKO PRO TLF Transmitter Adding Optional Items 2.3.1 Fiber Optic Remote Trigger and Beeper Unit To attach the Fiber Optic Remote unit to the pulseEKKO Pro deluxe handles, remove the screw near the top of one of the handles. Then attach the two pieces of the handle attachment assembly (Figure 2-3) and replace the screw as shown. Now press the Fiber Optic Remote onto the handle and twist it a quarter-turn into place.
pulseEKKO PRO TLF Transmitter 2-System Assembly and Startup Figure: 2-5 The steps necessary to complete the connection of the remote trigger and beeper unit are: 1) The black fiber optic cable of the dual cable connects from the red REMOTE receptacle on the console to the OUTPUT (grey) fiber optic connector on the remote trigger and beeper unit. This connection is necessary for the trigger part of the remote trigger and beeper unit to work.
2-System Assembly and Startup pulseEKKO PRO TLF Transmitter The odometer has 2 settings: string and wheel. The wheel odometer setting can be used in situations where a wheel or cart can easily be pulled across the surface. The string odometer setting is useful when conditions are too rugged for the use of a wheel. The odometer has both a fiber optic connection and an electrical connection (Figure 2-6). Either connection can be used to connect the odometer to the console.
pulseEKKO PRO TLF Transmitter 3 3-Troubleshooting Troubleshooting In this section, a thorough discussion of the error conditions will be presented together with a systematic step-by-step procedure for tracking down the source of the problem. 3.1 Transmitter Problem: No Signal on Screen a) In Graph mode try the Automatic timezero search. Keep the antennas about one antenna length apart.

pulseEKKO PRO TLF Transmitter 4 4.1 4-Care and Maintenance Care and Maintenance General To operate the pulseEKKO Pro equipment in a geophysical field environment, the user should exercise the normal care afforded other field instrumentation. Items that require specific maintenance procedures are listed below together with detailed descriptions of the procedures. All the equipment is ‘shower proof’ but will not tolerate total immersion.
4-Care and Maintenance pulseEKKO PRO TLF Transmitter Charge batteries at room temperature whenever possible. The receiver and transmitter contain a voltage monitoring circuit that will turn off the unit when the input voltage drops below 10.2 volts. If the voltage of the discharged batteries is measured some time after they have been changed it will be higher than 10.2 volts (this is normal). Do not mix charged and discharged batteries and DO NOT attempt to use discharged batteries a second time.
pulseEKKO PRO TLF Transmitter 4-Care and Maintenance All battery compartments should be checked periodically for proper operation. Take a known good battery and install into the four battery compartments. Ensure the power light activates with no intermittent operation. If the power light will not activate look in the battery compartment and check the battery contact for signs of excessive stress. Also check the condition of the 2A fuse wiring.

pulseEKKO PRO TLF Transmitter 5 5.1 5-Helpful Hints Helpful Hints Handling Fiber Optic Cables The fiber optic cables are the most fragile component in the system. They can be easily damaged by misuse. When handling the fiber optic cables always roll and unroll them as if they were on a spool. DO NOT roll them around your arm like a rope or extension cord. Also, these cables do not twist, therefore laying the roll on the ground and pulling the cable off will cause the cables to tangle. 5.

pulseEKKO PRO TLF Transmitter Appendix A - Health & Safety Certification Appendix A Health & Safety Certification Radio frequency electromagnetic fields may pose a health hazard when the fields are intense. Normal fields have been studied extensively over the past 30 years with no conclusive epidemiology relating electromagnetic fields to health problems. Detailed discussions on the subject are contained in the references and the web sites listed below.
Appendix A - Health & Safety Certification pulseEKKO PRO TLF Transmitter References 1. Questions and answers about biological effects and potential hazards of radio-frequency electromagnetic field USA Federal Communications Commission, Office of Engineering & Technology OET Bulletin 56 (Contains many references and web sites) 2. Evaluation Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields.
pulseEKKO PRO TLF Transmitter Appendix B Appendix B - FCC Regulations FCC Regulations This device complies with Part 15 of the USA Federal Communications Commission (FCC) Rules. Operation in the USA is subject to the following two conditions: (1) this device may not cause harmful interference and (2) this device must accept any interference received, including interference that may cause undesired operation.
Appendix B - FCC Regulations pulseEKKO PRO TLF Transmitter performed effectively only through the use of GPRs and wall imaging systems. We viewed these operating restrictions in the broadest of terms.

pulseEKKO PRO TLF Transmitter Appendix C Appendix C - Instrument Interference Instrument Interference Immunity regulations place the onus on instrument/apparatus/device manufacturers to assure that extraneous interference will not unduly cause an instrument/apparatus/device to stop functioning or to function in a faulty manner. Based on independent testing house measurements, Sensors & Software Inc. systems comply with such regulations in Canada, USA, European Community and most other jurisdictions.
