2. Insulation resistance mesurement (Only U.S.A. model)
Connect
the
insulating-resistance
tester
hetween
the
plug
of
power
supply
cable
and
the
terminal
GND
on
the
back
panel.
Specifications,
More than 10 MQ at 500V.
3. Voltage selector (rear panel)
Worldwide
models
are
equipped
with
a
voltage
selector
to
conform
with
local
power
supplies.
Be
sure
to
set
this
switch
to
match
the
voltage
of
the
power
supply
in
your
area
before
turning
the
power
switch
on.
Voltage
is
changed
by
sliding
the
groove
in

that
the
switch
has
been
moved
all
the
way
to
the
up
or
down
before
turning
the
power
switch
on.
Models
without
a
voltage
selector
can
only
be
used
in
areas
where
the
power
supply
is
the
same
as
that
of
the
unit.
