[. . . ] Working with the PS 20 4. 1 Detecting objects, Continued Retaining the measured depth value on the display To retain the measured depth value on the display after a rebar has been detected, press and hold the On key. This aids easy reading of the display when working in restricted areas. After releasing the key, the display is reset. Detecting non-ferrous metallic objects (copper and aluminium) Limitations of rebar detection and depth measurement 1. Shading Determining the center of the pipe: - the center indication light illuminates. - the non-ferrous metal symbol appears on the display The problem of shading can occur when trying to detect a second layer of reinforcement. Any reinforcement below the top layer that is shaded will not be detected. Mark the position through the hole in the sensor head using a marking pencil supplied. Mark the likely area through the hole in the sensor head using a marking pencil supplied. 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. 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. 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. 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. The minimum coverage icon disappears, signifying that the function is now inactive. To ensure that the function remains inactive switch the tool off and then back on. [. . . ] Worn Sensor head and battery compartment covers can also lead to a degradation of depth measurement accuracy of between -1 to -4mm. 7. - replace Error codes: E1 Sensor malfunction Measure: Ensure the calibration conditions have been fulfilled as described in chapter 3. 2. If error remains, contact Hilti Service E2 Temperature outside of safety range Measure: Switch off and allow to adjust to surrounding temperature for one hour. 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. [. . . ]
