1 Introduction __________________________________________________ Thank you for purchasing the EasyLocator HDR. The EasyLocator series of products is the most widely used GPR-system for utility detection, world-wide. The HDR-version is the latest in a line of easy-to-use tools for the locating industry. It builds on its predecessors in terms of handling and user interface while incorporating the latest and most potent technology currently available.
1.1 Unpacking and Inspection Great care should be taken when unpacking the equipment. 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.
1.4 Important information regarding the use of this MALA GPR unit According to the regulations stated in ETSI EN 302 066-1 (European Telecommunication Standards Institute): - The CX unit should not be left ON when leaving the system unintended. It should always be turned OFF when not in use. - The antennas should point towards the ground, walls etc. during measurement and not towards the air. - The antennas should be kept in close proximity to the media under investigation.
2 Hardware and Start Up __________________________________________________ 2.1 Hardware The EasyLocator HDR is a GPR system with integrated, height-adjustable wheels. The main components are the UWBtransducer(antenna), the monitor the mechanical carrying system and the batteries. The system is, preferable powered with one battery and data communication between the GPRtransducer and the monitor is managed with an Ethernet link on a cable which carries power to the monitor as well, see figure below. 2.
Connect the traducer to the battery by means with cable supplied, see picture below. Connect the Monitor to the transducer with the cable supplied, see picture below. Press and release the button the GPR-transducer, shortly, do keep it pressed. This will start up the unit; the LED’s on the panel will start to blink as well as the LED inside the button, see figure below. www.malags.
Press the button on the monitor; it’ll take about 30 seconds for the unit to start up. After these simple steps the monitor will display the screen shown in figure below, and the system is ready for operation. www.malags.
3 Using the EasyLocator HDR The EasyLocator is shipped folded, with monitor and cables attached, but without the battery mounted. You need to connect the two battery-packs together and mount the in the battery bay (this is due to shipment regulations for Li-Ion batteries). In figure below a folded EasyLocator ready for shipment is shown. In order to unfold the unit; just lift the monitor to upright position and fasten the clips on the side of the shackles. See figure below. www.malags.
Once the unit is un-folded and started as described in previous paragraph, operation is very straight-forward and selfexplanatory, some details will be described in the following text. Referring to the start-up screen is shown in figure below, the area of the screen between the depth scales are reserved for data presentation, the lower portion for information about the ongoing survey and the right column are mainly for controlling the instrument trough the turn-push button.
The scale with red, yellow and green indicates the battery status. It is divided into two black bars, since there’s an option of using a separate battery for the transducer. In other respects, this scale is self-explanatory. The Quit button is also self-explanatory, press on this and you’ll have the option for turning off the unit. Note that the unit should always be turned off this way, since just pulling the power cable may harm the internal memory of the unit.
3.1 Surveying When a survey has been initiated the main menu changes, see figure below. Now the user may stop the survey, save a jpeg-image of the current screen check the velocity trough hyperbola fitting or save a GPS-marker on the current location. An important feature in the instrument is the track-cursor pointed to by the red-arrow in the figure. This cursor will move with the system, so that if the unit is moved backwards, this cursor along with a vertical line will start to move back on the screen.
3.2 The settings menu The settings menu is entered through the wrench button on the main menu; it is shown in figure below. Activating the green text-fields, but turning the push-turn button, and then depressing it gives the user means for changing the settings. Below the different options are described. - - Color, the user can switch between gray-scale and color scale for the displayed radar data.
- Soil Type, is defining which ground velocity should be used when converting reflections from a specific time to a depth to be shown on the scales. Note that this type of instrument actually measures time of flight for electromagnetic waves, in ground. The depth displayed on the scales is estimations only. Variations in normal ground are between 80 to 120 meters/microseconds. A user must be aware of this fact.
