Probes; Ferrous (F) Probes; Non-Ferrous (N) Probes; Dual Ferrous/Non-Ferrous (Fnf) Probes - Elcometer 456 Operating Instructions Manual

7 PROBES

An extensive range of probes is available for the
Elcometer 456
ferrous (F), non-ferrous (N) and dual ferrous/non-ferrous
(FNF) operation are available as either integral (built-in)
or separate options.
Separate probes are fully interchangeable and are
available in standard, PINIP™ and miniature formats.
PINIP™ format (Plug-In Integral Probe) is an integral
style probe which plugs in to a separate gauge. This
provides all the benefits of an integral gauge and the
flexibility of a separate gauge in a single unit.
Miniature separate probes permit measurements where
space is restricted.

7.1 Ferrous (F) probes

F probes measure the thickness of non-magnetic
coatings on magnetic substrates. They can be used on
paint, plastic, galvanising, enamel, powder paint, hard
chrome and other coatings such as electro-less nickel
applied to steel or iron.

7.2 Non-ferrous (N) probes

N probes measure the thickness of non-magnetic
coatings on non-magnetic metals. They can be used on
anodising, paint, plastic coatings, powder paint, etc.
applied to aluminium, brass, non-magnetic stainless
steel, etc.

7.3 Dual ferrous/non-ferrous (FNF) probes

FNF probes are dual function, F and N in one probe. FNF
gauges will automatically detect the type of substrate
and set the mode accordingly. Alternatively the mode
can be set manually - see "PROBE:" on page 21 and
"Coatings on galvanised or metallised steel" on page 37.
e. Using an N probe (or an FNF probe manually set
to N1) on a ferrous substrate will give a reading,
but the reading will be incorrect.
