To adjust, simply loosen the knob, reorient the handle, and tighten. To remove the handle, fully loosen the knob. Flex LT Handle Adjustments Remove the Flex LT handle to attach the Telescoping Pole Accessory (sold separately). 360 degree range of horizontal motion. Vertical range of movement is limited to prevent display damage. Powering Flex LT Press both buttons to Power On. Hold both buttons to Power Off. Note: Battery contacts toward Flex LT and facing upward. To insert the battery, slide battery door latch to left, and open the door. Insert the battery in the orientation shown. Close the battery door and ensure that the door latch is fully engaged by pushing it to the right. Antenna and Marker Positions Flex LT incorporates two individual GPR antennas: A Standard Orientation antenna (in front) and a Cross Polarized antenna (in back). The center of each antenna has colored markers for highly accurate markouts. Red markers, located on the top, front, and sides, show the center points of the Standard Antenna. These markers are aligned to the red backup cursor during collection. Green markers, located on the top, back, and sides, show the center points of the Cross Polarized Antenna. These markers are aligned to the green backup cursor during collection. Scanning with both antennas produces a more detailed and informative view of concrete targets, especially for complex jobs. After powering on, Flex LT will start every new session at the Main Dashboard. Tap the icon to access system settings. Tap the icon to start a 2D scan. Flex LT Dashboard The Settings Menu is the control panel for customizing your Flex LT experience. Use this menu to assign quick button options, adjust volume, screen brightness and time/date, and change units and language setting. Tap the X to return to the Main Dashboard. Flex LT Settings Select Concrete Type Select the appropriate Concrete Type based on the state of concrete cure. This menu only appears once during each session. This setting will greatly impact depth readings. While collecting or viewing data, use the Depth Settings Menu to further refine the depth scale accuracy. The Last Used option will reuse the dielectric value from previous sessions. A blank data collection screen will appear. Tap the icon to initiate a scan, and then move Flex LT forward to begin collecting data. Data will populate from left to right. Move Flex LT in reverse to view backup cursors that align with the red and green colored markers on the top, sides, and front and back of the system. View the Top Navigation Bar Access and adjust the Gain, Display and Depth settings. Stop data collection Data Collection Screen Collecting GPR Data The GPR data will reveal two distinct categories of reflections: targets, and layers. Targets, such as rebar and conduit, are discrete objects below the surface and are represented by hyperbolas (orange boxes). Layers are continuous features, like the slab/grade contact (blue box). Closely-spaced targets, like wire mesh, produce abundant hyperbolas that overlap on the sides. Rebar and other metallic targets produce bright hyperbolas. Rebar targets are often spaced wider than wire mesh targets. Layers do not produce hyperbolas. They appear as continuous features that often vary in brightness and depth. Tap the icon on the depth scale to open a window with three nested menus: Gain, Display, and Depth. For now, click the Gain icon in the lower left. Here you can use the slider to adjust the overall contrast of the data, or select one of three general depth levels (shallow, medium, deep) to selectively adjust contrast. Improving Data Visualization Tap the icon at the bottom of the panel to adjust Display settings. Here you can quickly change your data display from split screen with both antennas to full screen options for the standard (front) and cross polarized (rear) antennas. You can also adjust color tables, toggle the O-Scope, or adjust Width Scaling.
