2. Use the battery clip to connect the 9 V battery with correct polarity.
3. Place the battery with the battery clip into the battery compartment.
4. Slide the cover back onto the battery compartment until it locks in place.

Switching the device on

Info
Please note that moving from a cold area to a warm area can lead to condensation forming on the device’s circuit board. This physical and unavoidable effect can falsify the measurement. In this case, the display shows either no measured values or they are incorrect. Wait a few minutes until the device has become adjusted to the changed conditions before carrying out a measurement.

1. Press the MODE/CAL button (2).
   • The device switches on.
   • The bar graph (6) flashes.

Selecting the measuring mode
You can choose between the measuring modes Stud frame, Power line and Metal.

1. Press and hold the MODE/CAL button (2) for approx. 3 s until the icon flashes in the mode indication (5)
   • The device will emit a brief acoustic confirmation signal.
   • The currently selected measuring mode flashes.
2. Repeatedly press the MODE/CAL button (2) until the icon for the desired measuring mode is displayed in the mode indication (5).
   • The device will emit a brief acoustic confirmation signal.
3. Wait a moment until the icon in the mode indication (5) stops flashing.
   • The desired measuring mode is selected.
   • The bar graph (6) flashes.
4. Hold the device against the surface at which the detection process shall be performed. Now press the MODE/CAL button (2) again to start a calibration for this surface and its material composition.
   • The bar graph (6) starts filling up from the outer edges towards the centre.
   • The device will emit a brief acoustic confirmation signal once the calibration has been completed.

Performing a calibration

Info
During the calibration as well as the later measuring process you should ideally only hold the device with your fingertips at the lateral black gripping surfaces near the bottom of the device.
After calibration and during subsequent measurements, try not to change the position of your hand or fingers.
Avoid placing your fingers on or moving them across the display since the sensitivity to power lines is significantly increased, especially in localization mode, and the capacitive field influenced by your hand or fingers could lead to measuring errors. Fundamentally, the more your hand cups and grasps the device, the greater will the measurement be influenced.
Please also note that static electricity, mobile phones (UMTS) as well as WLAN, radar, microwaves or nearby transmitter masts can be additional interference factors.
Moreover, both wet ground and metallic building materials (foil-laminated insulation material, conductive wallpapers etc.) may influence the measurement. Particularly if there is static electricity present during a measurement in Power line mode, this may lead to existing power lines being displayed imprecisely (e.g. over a large area) or not at all due to the high sensitivity of the measuring device. This is not a device malfunction but a physical effect. In order to reduce such electrostatic interference, hold your free hand flat against the wall next to the device.
After every switch-on of the device or whenever having changed the measuring mode, perform a calibration at a surface or wall with the same properties as the surface or wall within or behind which the material to be detected is located. Please note that for this calibration the material to be detected must not be located at or in the immediate vicinity of this position. Performing a calibration in the immediate vicinity of the material to be detected influences the sensitivity of the device with regard to this material and thus falsifies the localization results.

1. If at all possible, hold the locating device to the wall at a position where none of the material to be detected is located.
2. Press the MODE/CAL button (2).
   • The bar graph (6) flashes.
3. Make sure not to move the device during the calibration process.
4. Now press the MODE/CAL button (2) again to perform the actual calibration.
   • The bar graph (6) starts filling up from the outer edges towards the centre.
   •  The device will emit a brief acoustic confirmation signal once the calibration has been completed.

Info
If required, the calibration can also be performed during a localization process so as to achieve better results.
The first calibration however should always be performed on a neutral surface that is comparable to the one of the later localization.

Performing a localization
When the calibration is completed, you can start with the detection process.

1. Hold the device flat against the surface or wall and move it evenly in the desired direction while applying slight pressure. Due to the device’s functional principle, objects running transverse to the testing direction can be detected more clearly and thus more reliably.
2. Watch the bar graph (6).
   • From the number of bars or the frequency of the acoustic signal you can judge whether the material to be detected is in close proximity.
   • When locating wood or metal the display is illuminated in blue.
   • When locating live cables the display is illuminated in red and the warning signal changes.
3. Move the device sideways or up and down to get closer.

Info

• When an object is first approached or crossed, this is indicated by a rising bar graph and a change in the audio frequency. When pulling the device back in the opposite direction, its sensitivity is adjusted automatically so that the object will be displayed more clearly.
• If the device detects a live cable during a measurement, the display will be illuminated in red and the voltage warning indication (8) will flash –regardless of the localization mode the device is currently in.
• Please note that – being subject to wall structure and several superimposed material layers/object depth –the bar graph will not always be indicated fully closed, even in case of a precise localization!
  The display will indicate the maximum possible under these conditions.
  If the position of the material/object to be detected has already been narrowed down by a prior measurement, the result can further be improved by measuring in a closer range around the previously determined position. To do so, keep calibrating the device in radii getting progressively smaller around the expected location centre. This increases the sensitivity with regard to the material to be detected. Repeatedly perform measurements to verify the expected material position.

Switching the device off
The device switches off automatically after approx. 10 min of non-use.

1. Press the power button (2) for approx. 5 s.
   • The device switches off.
