Application range
With NFe probes the gauge is used to measure the thickness of electrically
non-conductive coatings on non-magnetic electrically conductive sub-
strates (e.g. aluminium, brass, copper) by means of the eddy current
method (DIN EN ISO 2360).
With Fe probes the gauge is used to measure the thickness of non-
magnetic coatings on magnetic substrate (e.g. iron, steel) according to the
magnetic-inductive principle (DIN EN ISO 2178).

Important notes (read prior to first start-up!)
The gauge must not be used in explosive environment. Follow your respec-
tive safety rules.
Don't switch the instrument on or execute measurement while it is exposed
to electromagnetic interference fields!
Keep the measurement set-up (instrument, cable, test block etc.) away
from sources of magnetic fields (neon light, transformers, mains units, elec-
tric motors etc.)!
This will avoid influences on the measurement result by external magnetic
fields and magnetization of parts under test.
If interference fields have been detected...
... the display will show the symbol
... measurement is not possible (the last measured value will remain on
the display)
... an acoustic error signal is generated.
Ensure that the substrate is free of magnetic remanence to a large extent.
Use test blocks only to check the proper function of the instrument. If a
special measurement calibration is required (see section 12) you need to
use the actual substrate for calibration.
With soft layers even a slight contact pressure may deform the surface and
falsify the measuring result. In this case try to place the probe without
spring force. Or select a compensating offset value (see section 10.2.3) if
either the upgrade level "Statistics"
installed.
The LEPTOSKOP 2042 is equipped with a monitoring unit for the battery
capacity which will switch the gauge off if a non-sufficient voltage supply is
detected. Prior to final switch-off caused by an empty battery an alarm
sound is generated. Set-up and calibration is memorized.
