Slides
A
total
of 11
slides are available, all
of which may
be
used together
with the Lumisphere and Lumidisc.
(Note
thatthey cannot be
used
with Lumigrid.) The
High

previously,
is
employed
for
varying the
measuiing
range in
2 steps
(high

low illumination), however, it
can also be
used
for
direct
reading.
The other slides are
specialized
for
direct
reading
and
cannot
be
used
for
mode selection.

of

consists
of slide

-
11 in
a case.
The
High
slide
can
also
be
used as a
direct
reading slide.
