MALÅ GeoScience RAMAC X3M and EasyLocator Hardware Manual 2 Important note: In the US this unit operates under FCC rules Part 15. According to these rules a GPR system shall contain a manually operated switch that causes the transmitter to cease operation within 10 seconds of being released by the operator. Therefore all units sold after July 15 2002, in the US, will have this functionality and also be delivered with a kill switch. Units sold outside the US will have a plug attached to the kill switch connector. Removing this plug causes the unit to cease functioning. No kill switch will be delivered to destinations outside US. The kill switch and how it’s to be handled is further explained in this manual. 3 Table of Contents ____________________________________________________________ 1.

Be sure to verify the contents shown on the packing list and inspect the equipment for any loose parts or other damage. All packing material should be preserved in the event that any damage occurred during shipping. Any claims for shipping damage should be filed to the carrier. Any claims for missing equipment or parts should be filed with Mala GeoScience. 1.2 Repacking and Shipping If original packing materials are unavailable, the equipment should be packed with at least 80 mm of absorbing material. Do not use shredded fibers, paper wood, or wool, as these materials tend to get compacted during shipment and permit the instruments to move around inside the package. 5 2 Start up and Hardware Description ___________________________________________________________ The RAMAC X3M/EasyLocator is an integrated radar control unit, mounted directly on the shielded antennas and powered externally. X3M is compatible with the RAMAC/GPR shielded antennas 100, 250, 500 and 800MHz. EasyLocator has it own family of shielded antennas; DEEP, MID and SHALLOW. The built-in electronic design makes it a low weight and compact size system, easier to assemble and operate. No fiber optic cables are required since the unit communicates directly with the laptop. Based on the flexibility and the modularity of the RAMAC/GPR, the RAMAC X3M is fully compatible with the Windows based acquisition software Ground Vision, while the EsayLocator has it own acquisition software: EasyVision. The built-in default autostacking function secures the best data quality at maximum survey speed, in both units. This section will give a short overview of how the GPR (Ground Penetrating Radar) systems work. 2.1Layout of the RAMAC X3M /EasyLocator Figure 2.1a. Layout of the X3M The different number in Figure 2.1 corresponds to the following: 1:Connector for kill switch 2:Power button 3:Connector for encoder, 9 pin d-sub (wheel or hip chain) 4:Connector for parallel cable to a PC, 25 pin d-sub 5:Securing screws for mounting on antennas 6:Power cable connection Figure 2.1.

The same connectors as in figure 2.1a showed on an EasyLocator. 2.2Mounting on the shielded antennas Start by placing the X3M/EasyLocator on the antenna that you are going to use for your measurement. The Parallel port and the Power connection should point forward according to the picture (Figure 2.2). Fasten the unit on the antenna by tighten the securing screws.

ON/OFF 7 2.3Power cable When the X3M/EasyLocator is mounted on the antenna connect the Power cable from your battery. Look for the countersink and place it towards the mark on the connection. Push lightly. If you have it in the correct position it should connect smoothly. To disconnect: Pull out, holding the milled part of the connection. 2.4 Distance measuring devices The X3M/EasyLocator can be used together with the standard MALÅ GeoScience distance measuring devices (hip-chain and measuring wheels). The encoder cable is connected as shown below (Figure 2.4) 2.5Connection to computer Add the computer to the system by connecting the parallel port cable between the computer and the X3M/EasyLocator (Figure 2.5). Use an IEEE 1284 compatible parallel cable that is less than or equal to three meters long. Figure 2.4. Encoder Figure 2.3. Power cable Figure 2.5. Parallel port 8 2.6 Kill switch The kill switch is attached to a handle that can either be handheld or snapped onto a RAMAC/GPR Cart (Figure 2.6 top). The X3M/EasyLocator will not be operational without the kill switch.…

According to the measurement procedures 51 cm (20”) of dry sand was placed in the ground, under the EUT. A ground plane, made by sheet metal, was formed around the EUT and protruding under the measurement antenna. The EUT was placed directly on the dry sand with no ground plane under it. Picture 1: Test Site The measurement distance antenna – EUT was 3 m. The measurement system and related equipment were placed in a van located 15 m behind the antenna.

Each measurement signal close to or above the limit was examined if ambient or related to the EUT. 4.3 General configuration of EUT The EUT was powered by its internal battery pack. The EUT was connected to a Malå Geoscience Control Unit CU II via fibre optic cables. The CU II was placed beside the test site, not being a subject of the test. No other cables were connected to the EUT or the Control Unit. No more connectors were provided on the EUT. 4.4 Operation of EUT during tests The Control Unit was gathering data from the EUT like in normal operation.
