- A)
- Depends on material and size of the objects, as well as material and condition of the substrate 
- B)
- For a copper pipe with a 15 mm diameter 
- C)
- For reinforcing steel with a 12 mm diameter 
- D)
- Lower detection depth with non-live wires 
- E)
- For wooden beams with a width of 54 mm, behind 30 mm thick plasterboard 
- F)
- Only non-conductive deposits occur, whereby occasional temporary conductivity caused by condensation is expected. 
- G)
- Weight without lithium-ion battery pack/non-rechargeable batteries/rechargeable batteries/battery compartment cover 
The serial number (19) on the type plate is used to clearly identify your measuring tool.
- The accuracy and detection depth of the measuring result may be negatively affected if the condition of the substrate is unfavorable.
