Calibration
Clean all components with a damp cloth and do not use
cleaning agents, scouring agents and solvents. Store the
device in a clean and dry place.
The device needs to be calibrated and tested on a regular
basis to ensureit produces accurate measurement results.
We recommend carrying out calibration once a year.
Contact your authorised dealer or else the
UMAREX-LASERLINER Service Department.
Always switch off the power supply when working
near electric wires.
!
Continuous current monitoring in unshielded wires
as soon as an electrical field is detected.
STUD-SCAN / METAL-SCAN Current monitoring
Special things to note with various materials
It may not be possible to detect wooden studs or joists
through the following materials:
– Ceramic floor tiles
– Fitted carpeting with padded backing
– Wallpaper with metal fibres or metal foil
– Freshly painted, damp walls. These must have dried
for at least one week.
– In problem cases, use METAL-SCAN to localise nails
or screws in dry walls that line up vertically where
a stud is located.
