[. . . ] Ferroscan System FS10 Bedienungsanleitung Operating instructions Contents 1. 18 Main functions The Ferroscan FS10 system provides the following main functions: q Rapid detection and verification of minimum concrete coverage (see section 5. 4). q Scanning and recording of images, with determination of depth of coverage and diameter of reinforcement (see sections 5. 2 and 5. 3). 23 Determination of position, coverage and diameter of reinforcement . [. . . ] 22 The battery is charged and provides its power via the two power terminals (a). The charger monitors battery cell temperature via the temperature control terminal (b), protecting the battery from damage due to overheating. q The RB10 battery does not suffer damage even when left in the charger for long periods. Safety precautions: See page 17, section 3 5.

The hand side of the screen. Set up menu appears at the right- Note: As a result of the detection principle utilised, reinforcement which runs parallel to the direction of movement of the scanner cannot be detected. The grid area must be scanned in two directions, at right angles to each other. Note: In order to receive a correct image, it is necessary to follow the prescribed scanning traces in the prescribed sequence. A) Attach the supplied paper reference grid, using adhesive tape, to the surface of the concrete. Alternatively, if the condition of the surface does not allow the use of adhesive tape, the grid can be marked directly on the concrete using the ruler. Optimum results will be achieved when the grid axis lies parallel to the reinforcement. B) Connect the RS10 scanner to the RV10 monitor using the RC10 connecting cable. The starting position of the scanner is shown on the screen in black. Select the Volume , Date , Time or Display keys. Language and unit of measurement (mm/inch) can be set by selecting Display .

Press the start/stop button on the scanner or the Start key on the monitor. Note: Incorrect or inaccurate positioning of the scanner will result in "shifting" of the image and the indicated location of the reinforcement will be incorrect. In order to cover the entire area completely, it must be scanned according to the specified grid, in vertical and horizontal directions. Marks are printed on the papier reference grid as an aid to positioning the scanner. If the reference grid is marked directly on the concrete surface using the ruler, the scanner must be positioned according to the effective scanning width represented by the grid. When the 600 mm trace has been fully scanned, an acoustic signal is given automatically. The scan can be interrupted before reaching the end of the 600 mm trace (e. g. In this case, the start/stop button on the scanner or the Stop key on the monitor must be pressed. On the screen, the starting position for the scanner moves automatically to the next trace. D) Repeat the procedure described at C) in the correct order for the remaining seven traces. The vertical and horizontal scanned areas are displayed on the screen in black. [. . . ] A picture image records all data for the reinforcing bars within the area of the scan. This enables position, depth and diameter to be determined subsequently. A quickscan image records the length of the scan, position and number of bars as well as depth of coverage over the bars that lie at right angles to the direction of the scan. When the image to be printed appears on the screen: ­ connect the printer ­ press the key It is recommended that the operator keeps a systematic record of the information relating to each image. Note: To connect the printer a printer cable (36-pin Centronics / 25-pin sub D type) is required. [. . . ]
