Geophysical Survey Systems, Inc. Model 52600 Antenna System Settings and User Notes Certificate To Whom it may concern: This is to certify that electromagnetic radiation emissions from transducers (antenna with transmitting and receiving electronics) manufactured by Geophysical Survey Systems, Inc. (GSSI) DO NOT constitute a safety or health hazard to operating personnel. Emissions from GSSI transducers are below the 10mW/cm² (100W/m²) level specified by the United States Occupational Safety and Health Administration (OSHA) regulations Paragraph 1910.97 states: "For normal environmental conditions and for incident electromagnetic frequencies from 100 MHz to 100 GHz, the radiation protection guide is 10 mW/cm² (milliwatt per square centimeter) as averaged over any possible 0.1 hour period." Emissions data using GPR SIR System-10, SIR-2, SIR-3, SIR-4, SIR-8, SIR-20, SIR-2000 and SIR-3000 (at the standard Pulse Repetition Frequency of 100 KHz) with the antenna Models listed and levels of Electromagnetic Radiation are specified herein: Following is the average power density data at 5cm and wide band.

Geophysical Survey Systems, Inc. Model 52600 Antenna System Settings and User Notes Model 52600 Antenna Thank you for purchasing a Model 52600 antenna. The Model 52600 represents the current state of the art in high resolution concrete structure imaging. The Model 52600 antenna has greatly improved resolution over previous high frequency antennas. Not only is the frequency higher, but the antenna has the ability to see objects at very close distances. The Model 52600 is the highest frequency ground coupled antenna available on the market today. Note: The Model 52600 antenna cannot be used with the large, three-wheeled utility cart without the survey wheel adaptor cable. If you intend to use the antenna with the utility survey cart, contact your GSSI account representative to make sure that you have all of the necessary cabling. System Setup - Standard Settings Note: You must follow these setup instructions exactly to use the Model 52600 antenna. Positioning of the signal will be the last step in the process. System Run Mode: Survey Wheel (recommended) or Continuous Range: 8 ns Number of Gain Points: 2 Vertical Low Pass FIR Filter: 5000 MHz Vertical High Pass FIR Filter: 400 MHz Vertical High Pass IIR Filter: 10 MHz Samples per Scan: 512 Bits per Sample: 16 Transmit Rate: Set to the maximum rate allowed by the SIR System, but not higher than 200 KHz. Scans per Second: Set to the maximum scan rate allowed by the SIR System. Signal Position Place the antenna on the concrete floor and use the Automatic Signal Position selection. You may need to try this 2 to 3 times to get the system to lock on to the surface pulse. If after 3 tries the surface pulse is not in the signal window, point the antenna into the air and again try the Automatic Position. To test that you have the correct position, raise the antenna off the ground and you will observe on your system that the antenna transmit pulse will separate from the reflection from the ground. The higher that you raise the antenna, the further apart will be the two pulses. Manual MN31-715 Rev - 1
Geophysical Survey Systems, Inc. Model 52600 Antenna System Settings and User Notes Gain Check The surface pulse should be about 2/3 the width of the screen. If it is greater, reduce the Gains manually. If the signal appears too small you can manually increase the Gains, but the first gain point should never exceed 10dB. Minicart Your Model 52600 is designed to fit into the Model 614 or Model 615 minicart. Using the antenna with the minicart allows you to take advantage of distance-based data collection which is possible with a survey wheel. A survey wheel (rear-axle of the cart) tracks the distance traveled and allows consistent scan spacing. The minicart is available as a separate purchase and is also compatible with the Model 5100/5100B high frequency general purpose antenna sold with the StructureScan systems and the Model 5101 deep penetration concrete antenna. Please contact your GSSI account representative for details. Note: The red switch on the underside of the minicart’s handle operates as a ‘deadman’ switch. The switch must be fully depressed to activate the transmitter. If you release the red switch during data collection, the system will automatically turn off the transmitter within approximately 10 seconds unless you depress the switch again. This feature makes it legal to scan walls and ceilings within the United States and the European Community. Operation of the 52600 on a wall or ceiling without a ‘deadman’ switch enabled cart or handle constitutes illegal operation within the USA as per FCC regulations or within the European Community as per EU regulations. Data Collection Collecting Data Using The Survey Wheel With The Standard Settings System Run Mode: Distance. Number of Scans per Meter: 300 (90 scans per foot) or higher Remote Operation • Pressing the thumb rocker switch button for less than one second will place a marker in the data. • Pressing the button for longer than 6 seconds will close any open files and turn off the transmitter. To resume, the data acquisition sequence must be repeated. Manual MN31-715 Rev - 2
Geophysical Survey Systems, Inc. Model 52600 Antenna System Settings and User Notes Special Settings Used For Collecting Data On Bridge Decks Setup Mode: Manual System Run Mode: Survey Wheel Range: 6 ns (unpaved), 10 ns (paved) Number of Gain Points: 1 Vertical Low Pass FIR Filter: 5000 MHz Vertical High Pass FIR Filter: 400 MHz Vertical High Pass IIR Filter: 10 MHz No Horizontal Filters Samples per Scan: 512 Bits per Sample: 16 Transmit Rate: Set to the maximum scan rate allowed by the SIR System but not higher than 200 KHz. Scans per Second: Set to the maximum scan rate allowed by the SIR System. Signal Positioning: Use the same procedure as in standard setup Set the Scans per Meter parameter to 80 scans per meter (24 scans per foot) Calibrate the survey wheel before collecting data Note: See Bridge Assessment Manual before proceeding.

Geophysical Survey Systems, Inc. Model 52600 Antenna System Settings and User Notes Specifications Center frequency: 2600 MHz Pulse duration: 0.4 ns Depth of penetration: 0-12 inches depending on type of concrete Size of sensor: 1.5 x 4 x 6.5 inches (3.8 x 10 x 16.5 cm) The 52600 controller box has two brackets to mount the box to the extension handle. The thumbscrews are provided with the SIR-3000. The connector with the red circle is for the control cable (direct to the SIR-3000). The connector with the blue circle is for the survey minicart cable. This cable carries the information from the survey wheel, marker switch, and the bar code reader. Manual MN31-715 Rev - 4
