(SENSITIVITY

For more than twenty five years technicians all
over
the
world have been using l.C.E. Test
Meter analysers
manufactured by
the
lndustria Costruzioni Elettrorneccaniche. Their confidence
in
our products
is
due
to
the
continuous effort.
on our part t0
keep abreast
of the
new
technological requirements
caused
by the rapid progress made in the
electrical and electronic
fi
e
lds.
This new
"Supertester 680
R" offers
many
features which are the
result
0f
the
most up t0
date techniques,
backed
by many years
of
experience and testing
in
0ur
laboratories.
It
is
very practical due
to its
quality,
numerous features and
its
size (128 x 95 x
32
mm-).
Modern metallic layer resistors have been used, which, as well
as
giving a precision of 0.5%,
guarantee this precision with a
stabillty
in
absolute time that
is
four times
above
the
normal
"precision"
resistors used
in
Test Meter
analysers.
These alone
put the
"Supertester 680 R" above
all
other analysers manufactured up
to
now.
Furthermore
a
large mirror
scale
allo,ls rnore precise readings
from
the
"Supertester
6E0 R"
by avoiding parallax
errors.
A glass cartridge fuse, r6ted at
160 mA, forms
part of the
Resistance measuring
circuit,
since
experience has shown that 90% of
resistor
failures in
multimeters are caused by
the
inadvertenl
failure to
re-seiect the correct function and
range, when changing
fr0m a
resistance
to
a
voliage
measurement.
Four spare fuse-links are provided, conveniently mounied within the
instrument
on
the
meter back-piate.
With the Supertester 680 R
it
is
possible
to
carry
out
all
measurements, even those which
need mains connection, without having
t0
extract the Test Meter from the
Carrying
case.
The
new patented carrying case, as well
as having an invisible double base
t0
contain
the
probes
and other
accessories,
allows the analyser
to
be
set at 45" in
respect
to
the
support, {acilitat-
ing the
reading
of the quadrant.
The use
of the
compensated
magnetic nucleus indicating
instrument
fully
shields
the
instru-
rnent against external magnetic
fields, providing
it
with
absolute stability
in
calibration,
