General Assembly of parts Controller 1. 2. 3. Remove the controller from the carry case and place on a level and stable surface. Remove the protective covers from the two circular connectors. Connect the 1 m black curly power cable to the controller power socket, ensuring that the connector is securely fastened and the collar has locked. Note on circular connectors: The circular connector is a robust, positively locking, keyed connector.
Installing the Head Electronics unit into an antenna The following describes how the Head Electronics unit is installed into an antenna. However, the same procedure is followed for installing the Head Electronics unit into the 1 GHz and 2 GHz belt box. These first steps describe the installation of the Head Electronics unit into the antenna. Generally it will not be necessary to follow these steps, as the radar head will already be installed in the antenna. 1. 2. 3.
4. Without twisting or trapping the cables, insert the Head Electronics unit into the antenna. The Head Electronics unit should now be pushed firmly, but not forced, until the front plate reaches the antenna housing. Note: The cables are designed to lay across the width of the case to give smooth cable flexing and are moulded to achieve this.
The pull handle system The pull handle system is in four parts: 1. 2. 3. 4. The grip - dummy or function handle. The adjustable top shaft. The central tube. The clevis, which is used for antennas of frequencies 500 MHz and lower. Assembly of pull handle Fitting the clevis 1. 2. 3. 4. Point the two feet of the clevis away from you with the lever upwards. Loosen the lever and insert the closed end of the central tube into the bracket so that the wide portion just below the weld sits inside.
Fitting a grip Two grips are available; a plastic dummy grip or a function handle with integral push buttons. Both are attached to the pull handle in an identical fashion. 1. 2. 3. Remove the PIP pin from the grip. Push the grip onto the small stub fixing. Insert the PIP pin and push in as far as it will go. It will almost certainly be necessary to move the grip to ensure that the holes line up.
Setting up for field use Connecting the antenna/Head Electronics unit combination to the controller Requirements: 1. 2. 3. 4. 5. Place the antenna on the floor with the handle pushed forward. Select either the 2 metre long or 25 metre long, grey data cable. Attach the female connector to the central circular socket on the Head Electronics unit. This socket is marked “CONTROLLER”. Attach the male data cable connector to the large circular connector on the controller unit.
1. Remove the carry harness from the bag and remove any twists from the straps. 2. Put your arms through the arm loops. The large pads should sit on your shoulders. The two silver rings should be positioned on either side of your waist and the large, black, push fit waist connector at the front. Fasten the push fit belt and chest connectors. Make sure the two thin webbing waist straps are free and at about two-thirds extension.
6. 7. Fasten the other end to the battery pack. Now attach the visor to the controller. 8. Readjust the harness straps to ensure that you can comfortably view the controller screen, without any unnecessary straining or craning of the neck. 9. Now connect the antenna to the controller by means of the grey data cable. 10. The radar is now ready for proximity sensor calibration and use.
The Standard Trolley Option The standard trolley is assembled in the following sequence: 1. Hold the yellow wheel unit so that the battery bag is pointing towards you and the arrow marked on the frame is pointing away from you. 2. Lift and lower the two metal catches to open the large, black bracket. 3. Take the central handle tube with clevis attached and slot into the bracket. The flat faces point up and down. In addition, the clevis lever should also point upwards and the clevis away from you. 4.
18. Connect the straight black cable from the shaft encoder to the socket marked “ENCODER”. It might be necessary to organise this cable to prevent it dragging along the floor. Adding the controller 19. Hold the controller and align the computer handle runners with the machined brackets on the back plate of the controller. 20. Slide the controller down the runners. 21. Fasten the controller in place by means of the two plastic headed bolts on the computer handle mount. 22.
Pictorial Guide To Assembling the System This brief guide should help in the assembly of the trolley. Please refer to the text for clarification.
Secure with the PIP pins Locate and fix the function handle to the stub. Lock it in place with the PIP pin supplied Loosen the locking clamp and straighten antenna so that it lies flat.
Fix the controller in place with the two screws Connect the grey data cable to the controller - MALE end Connect the three cables to the Head Electronics unit in the antenna Place the batteries in the battery bag
Connect the battery to the controller using the black curly cable Turn on the radar!! Fix the visor on the controller
Proximity Sensor Calibration All ERA Technology antennas, except the 2 GHz unit, are fitted with a proximity sensor. This is to prevent the system from transmitting radio frequency energy into the air (a requirement of many national certification agencies). It must be calibrated on every occasion that the Head Electronics unit is powered up. Failure to do so will mean that the radar will not transmit. In addition, a secondary safety device is built into the grip of the function handle.
Office Mode In office mode, the radar operator has the ability to carry out tasks which are not suitable in the field, such as data backup, data processing and printing out radar data or report writing. As the SPRscan controller is running the Windows for Workgroups 3.11 environment, it is easy to install and run favourite or necessary software such as a word processor, drawing package etc. Setting up the controller in office mode: 1. 2. 3. 4. 5. 6. 7. 8.
Using Optional Peripherals Printer: If you have a printer, plug the printer data cable into the socket marked “PARALLEL”. External Monitor: The controller is capable of driving an external VGA monitor. If you have one, this is connected to the socket marked “MONITOR”. Note: When an external monitor is connected, the built-in screen will not be powered.

Limitations on using the SPRscan The SPRscan surface penetrating radar has been designed to be a field rugged surveying system. It is perfectly suited for use in a wide variety of environments and conditions. However, there are some conditions to which it is not suited and therefore use of the SPRscan should be avoided where these prevail. These fall into two categories: 1. 2.
Maintaining the SPRscan System The ERA Technology SPRscan radar system has been designed to be a rugged piece of surveying instrumentation. It should require a minimum of maintenance to keep it serviceable. However, a few simple, common-sense procedures and rules should be followed to ensure that this is the case. Please bear in mind that whilst it is rugged and field useable, it is not indestructible! • • • • • • • • • • • • Avoid knocking, banging or dropping the controller.

SPRscan Electromagnetic Compatibility (EMC) 1 Design Aims SPRscan is designed for electromagnetic compatibility with other electrical and electronic equipment sharing its intended working environment. Under some circumstances identified below, certain procedures may need to be adopted in order to ensure that compatibility is maintained.
5 Limitations 5.1 Intense Radio Frequency Fields Due to the presence of a wideband radio receiver as part of the systems intrinsic function, SPRscan may not provide reliable data in the presence of high level radio frequency energy. Under some conditions this energy can be detected by the system's radio receiver and cannot be distinguished from the reflected energy of the built-in transmitter, thereby masking the wanted signals. Very high levels of radio frequency energy will overload the receiver.
6 Operation of SPRscan with User Supplied Peripherals SPRscan has been EMC tested with a representative selection of typical commercially available peripherals such as monitors, tape backup units and printers. Users may source peripherals from reputable manufacturers subject to some simple precautions.
