[. . . ] PS 20 GB Operating instructions Operating instructions PS 20 PS 20 Detector This operating instructions contains information on how to use the tool as well as safety notices (see chapter "Safety notices"). Please read these instructions carefully before using the tool. Also place it at the disposal of anyone who is to use the tool. We recommend keeping the instructions and tool together. Content PS 20 Detector 1. [. . . ] To return to the metal detection mode, press the On key. 2. Influence of reinforcement mats on depth measurements Although such a situation rarely occurs, a reinforcing mat that lies up to 60mm deeper than the reinforcing bar can influence the magnetic field produced by the tool and result in an incorrect measurement. Localising live electrical cable See chapter 4. 2. 6 11 4. Working with the PS 20 4. 2 Menu Functions 4. 2. 1 Calibration Calibrating the tool enables it to ensure accuracy regardless of temperature change or surrounding magnetic influences. Calibration is automatically required when the tool is first switched on. Thereafter it will also automatically be requested either when the temperature in the tool changes by ±3°C (+26/37°F) or 6 minutes after the previous calibration. You will not be able to carry on working until this calibration is carried out. See chapter 3. 2 Switching on and calibrating. 4. 2. 2 Setting minimum depth of coverage With the minimum coverage depth set, the tool will only sound the visual and audible alarm when reinforcing bar is detected closer to the surface than the defined minimum depth. This function is used for checking minimum concrete coverage depth for: - quality control - assessment of cover on concrete areas prior to renovation - check before drilling holes for anchors To set the minimum coverage depth and activate the function: 2x 1. Select the minimum coverage function from the menu by pressing the function key twice. The minimum coverage icon flashes in the function menu. Press the right arrow key to set the desired depth. Keep the key pressed to quickly scroll to the value you require. Use the left arrow key to descend to a lower value if required. Press both arrow keys together to reset to zero. If you suspect a recalibration is required before it is automatically requested, carry it out by: 1. "CA" blinks in the main display and in the function menu. Hold the tool at least 1m away from any metal objects. Press the On key to carry out the calibration. 3. Press the On key to confirm your choice and return to the detection mode. The minimum coverage icon is displayed in the function menu, signifying that the function is active. Nonferrous metals will still be detected in the normal way. This setting is saved when the tool is switched off. 12 Continues 4. Working with the PS 20 4. 2. 2 Setting minimum depth of coverage, Continued To deactivate the function: 1.

If error remains, contact Hilti Service E3 Calibration cannot be carried out Measure: Ensure the calibration conditions have been fulfilled as described in chapter 3. 2. If error remains, contact Hilti Service 6. 2 Storage Clean and dry the tool. Do not repackage equipment until totally dry Storage temperatures: -20°C to +60°C / -4°F to +140°F . [. . . ]
