Operation Searching for iron bars in concrete 1 • Scan mode:Single Detection • Scene:Dry Concrete 2 1. Iron bar 2. Concrete 1. Turn on the scanner. If the scanner has already been switched on, press the mode button ( 2. Select the scan mode of “Single Detection” and press the apply button ( ). 3. Select the scene of “Dry Concrete” and press the apply button ( ). NOTE • To start scan operation, wait for the operation guide arrow to be shown. 39 ).
Operation 4. Align the guide laser (the sensor's right and left edge lines) with your intended line to scan, and apply the scanner to the concrete surface. 5. Move the scanner slowly side to side. 6. Scan results are shown on the display. 7. Make markings at the detected iron bar locations. (See page 34.
Operation Searching for wiring resin pipes in concrete • Scan mode: Multi Detection (*) • Scene: Dry Concrete 1 2 (*) For wiring resin pipes, which are often meandering unlike iron bars, it is recommended the Multi Detection mode which can scan three lines be used. 1. 2. Resin pipe Concrete 1. Place masking tape to the concrete surface to show scan lines in a square shape of 60 cm (23 5/8"). 1 3 4 A 2 B 5 1. Masking tape 2. Three lines to be scanned 3. Upper line 4. Middle line 5.
Operation 3. Select the scan mode of “Multi Detection” and press the apply button ( ). 4. Select the scan mode of “Dry Concrete” and press the apply button ( ). 5. Align the guide laser (the sensor's right and left edge lines) with the upper masking tape line, and slowly move the scanner on the line. 6. Scan results are shown on the display. The scan results of the “upper line” are shown in line 1 if the scanner is released from the concrete surface.
Operation 7. Align the guide laser (the sensor's right and left edge lines) with the middle masking tape line, and slowly move the scanner on the line. NOTE • Start scanning on the vertical masking tape line so that the starting position of scan can be aligned with that of the upper line. 8. Scan results are shown on the display. The scan results of the “middle line” are shown in line 2 if the scanner is released from the concrete surface. 9.
Operation 10. Scan results are shown on the display. The scan results of the “lower line” are shown in line 3 if the scanner is released from the concrete surface. • Resin pipes, which in many cases are not straight but are meandering, give often their scan results as marks located at differing positions and depths depending on each line. 11. You can recheck scan results and the locations of buried objects if the scanner is moved again from the position at which scan operation was started.
Operation 12. Make markings at the detected resin pipe locations. A A A: 30 cm (11 13/16") B: 60 cm (23 5/8") *It helps you identify the position of the buried object more easily if you scan also in the vertical direction with the scanner oriented perpendicularly.
Operation Searching for a pillar behind a gypsum board • Scan mode:Single Detection • Scene:Partition 2 1 1. 2. Pillar Gypsum board 1. Turn on the scanner. If the scanner has already been switched on, press the mode button ( 2. Select the scan mode of “Single Detection” and press the apply button ( ). 3. Select the scan mode of “Partition” and press the apply button ( ). 46 ).
Operation 4. Align the guide laser (the sensor's right and left edge lines) with your intended scan position, and apply the scanner to the gypsum board. 5. Move the scanner slowly side to side on the partition's surface. 6. Scan results are shown on the display. • In the case of a wooden pillar behind a gypsum board, the depth may not be shown. 7. Make markings at the detected pillar locations. (See page 34.) NOTE • Detection may be instable when the scanner has just been started up.
Operation Searching for iron bars in a block fence • Scan mode:Single Detection • Scene:Radar View 2 1 1. 2. Block fences Block fences generally have a structure as shown at right. Iron bars are placed between blocks, and mortar is filled around each iron bar. Iron bar Block fence 1 4 1. 2. 3. 4. 2 3 4 4 Void Mortar Iron bar Block In this example, use the scene of “Radar View” to be able to detect both iron bars and block voids. 1. Turn on the scanner.
Operation 3. Select the scan mode of “Radar View” and press the apply button ( ). 4. Move the scanner slowly side to side on the block fence's surface.
Operation 5. Scan results are shown on the display. Buried iron bars and voids each appear in waveforms as shown at right. Estimate the locations of iron bars through the characteristics and positions of the waveforms. Iron bar: Waveforms appear in deeper positions from the scan surface. Block void: Waveforms appear in shallower positions from the scan surface. 2 1 1. 2.
Operation To scan better Before scan operation • Remove dirt, dust or iron powder, if any, on the surface to be scanned. • Scans cannot be done correctly if the surface to be scanned is wet. Make sure the surface is dry. • If the surface to be scanned has large projections, they may interfere with the scanner's scan operation.
Operation Locations of buried objects The top of a parabolic form waveform represents the surface of the buried object. When the scene is set to “Dry Concrete” or “Wet Concrete,” burial detection marks appear all in the same size irrespective of the width of each buried object. When the scene is set to “Partition,” an oval mark corresponding to each width appears. 1 A 2 3 1. Surface being scanned 2. Upper surface of an iron bar 3. Black band A: 9.
Operation When adjacently buried objects are detected When buried objects are adjacent to one another, they may not be shown as independently individual single objects. Detected as independent two pieces Detected as one piece NOTE • In the case of the selection of an excavation or boring place, allow the scan starting position to have a good distance from the detected place. Scan direction The detection accuracy is the highest when the buried object and the scanner are positioned in parallel.
Operation The correct detection may be prevented when the buried object and the scanner are not positioned in parallel. When how iron bars are placed in concrete is unknown, scan in more than one direction. The correct detection may be prevented when the buried object is right in front of the scanner and in parallel to the scan direction. In that case, scan at more than one position.
Protection System Protective functions for the scanner and the battery When the scanner is being used, if any of the following protection functions is triggered, an error screen shown at right is displayed. This is caused by the protection function and is not a sign of malfunction. Protection function Error display • Temperature error (high/low) When the scanner is hot (cold), during which the correct scan is prevented, the message shown at right appears and the scanner is forced to turn off.
Protection System • Speed excess protection function When your operation is too fast, during which the correct scan is prevented, the message shown at right appears and prompts you to correct your operation.
Maintenance WARNING Always be sure that the tool is switched off and the battery cartridge is removed before attempting to perform inspection or maintenance. Care of the product • Wipe the product clean using a dry cloth or a cloth with a diluted neutral detergent. NOTE • Never wash the product with water. The entrance of water inside the product may cause a malfunction. • Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result.
