Recalibration
When measuring indicator i indicates a continu-
ously high amplitude in the operating mode
"Metal", even though there is no metal object
near the measuring tool, the measuring tool can
be manually recalibrated.
– Switch the measuring tool off.
– Removal all objects near the measuring tool
that could be detected, including your wrist
watch or rings made of metal, and hold the
measuring tool up.
Pay attention that battery indicator h indi-
cates at least 1/3 capacity:
Hold the measuring tool in such a manner
that the type plate 13 faces toward the
ground. Avoid bright light sources or direct
sunlight from shining on the area 12 and 13,
without covering off this area.
– Press and hold buttons 5 and 7 until the illu-
minated ring 1 lights up red. Then release
both buttons.
– When the calibration was successful, the meas-
uring tool will automatically start after a few
seconds, and will be ready for operation again.
Note: If the measuring tool does not automatical-
ly start, repeat the recalibration. If the measuring
tool still does not start, send it in the provided
protective pouch to an authorised customer serv-
ices agent.
