is one
of the comprehensive
range
of
accessories
specially
designed
to enhance
ihe
usefulness
of the l.c.E.
,,supertester,,,
Model
6g0
Series,Mu ltimeter.
The
small
rectangular
moulded
unit
contains
a
printed
circuit
board
carrying
a single-stage
transistor
amplifier,
together
vrith
its
associated
components.
These
include
a variable

100,000',.
Power
for this
accessory
is drawn
from
ihe multimeter
resistance
measuring
circuitry. The
n0rmal
test-prod
leads may
be inserted
into
two 2
mm
sockets
at one
end
of the
unit; t*o
flyJeads
at the other
end, terminatec
in 2
mm wander-plugs,
being
connected
to
the multimeter.
current
passing
through
the
resistor
under
test
is amptified
by
a factor
of 100,000
and applied
to the
"680"
metering
circuit.
