1.FEATURES
* It meets the standards of both ISO2178
and ISO 2361 as well as DIN, ASTM
and BS. It can be used both in the
laboratory and in harsh field conditions.
* The F probes measure the thickness of
non-magnetic materials (e.g. paint,
plastic, porcelain enamel, copper, zinc,
aluminum , chrome etc.) on magnetic
materials (e.g. iron, nickel etc.) . often
used to measure the thickness of
g a l v a n i z i n g l a y e r, l a c q u e r l a y e r,
porcelain enamel layer, phosphide
layer, copper tile, aluminum tile, some
alloy tile, paper etc.
* The N probes measure the thickness of
n o n - m a g n e t i c c o a t i n g s o n n o n -
m a g n e t i c m e t a l s . I t i s u s e d o n
anodizing, varnish, paint, enamel,
plastic coatings, powder, etc. applied
to aluminum, brass, non-magnetic
stainless steel, etc.
* Automatic substrate recognition.

4.MEASURING PROCEDURE
4.1 Press the power key to switch on the
power and '0' displays on the Display.
3-19
The gauge will restore the last
operation on display itself, with 'Fe'
3-20
or 'NFe' symbol showed on Display.
The gauge enters the auto mode
3-21
which can automatically recognize
the substrate itself.
3-22
4.2 Press the probe on a coating layer to
3-23
be measured. The reading on the
display is the thickness of the coating
layer. The reading can be corrected
by pressing the Plus key and Minus
key while the probe is away from the
substrate or the measurement body.
4.3 To take the next measurement ,just
l i f t t h e p r o b e t o m o r e t h a n 1
centimeter and then repeat the step
above . The gauge can memorize th e

4.4 To change the measurement unit 'um'
or 'mil' by Depressing
and not releasing it till 'UNIT' on
the Display and then pressing Zero
key (3-3) .
4.5 To change measurement mode from
the single to continuous or vice visa,
just depressing Power key and not
releasing it till 'SC' on the Display
and then pressing Zero key (3-3). The
symbol 'STATS' represents single
mode .
5. STATISTICS

statistical analysis of readings as they
are taken.
The statistics available are:
* Last value
* Mean value marked by Ave
* Highest Reading marked by Max
* Lowest Reading marked by Min
