MAINSAOAPTOR
The Mains
Adaptor supplied has
been specially
designed to
power
your
Meteor
Frequency
Counter.
lt
is suitable
for
the
normal mains
supply in thecountryof
purchase.
lt
is
NOT
protected
against continuous
short circuit but will
cause an
internal
nonresettable
thermal trip to operate. NO
OTHER
MAINS
ADAPTOR
(EVEN
IF
APPARENTLY IDENTICAL)
MAY
BE USED ON A
METEOR FREOUENCY
COUNTER. Such use
will invalidate the guarantee
and
may
damage the counter.
POWER AND
BATTERIES
Switch
(1).
This has three
oositions:
'Fast
Charge'will
re-charge
fully
discharged
cells at the
maximum
rate con-
sistent with not
overloading
the mains
adaptor.
There is no
provision
for
sensing
fully charged cells
and
the
user must satisfy himself that
use of this
facility
will
not
overcharge, overheat
or otherwise damage the
cells
in
use. Do
not
use in this
position
for more
than
one hour
and
then
only
on fully
dis-
charged
cells.
'Off'
disables the instrument but
allows
trickle-charging of
the
cells. Nickel-
Cadmium cells of
at least
1.2 ampere-hour
capacity may
be safely
trickle-
charged indefinitely
in
this
position.
'On'
applies
power
to
the
instrument from internal
cells or
preferentially
from
the mains
adaptor
if
used.
lf the mains adaptor is
used
with
the cells
in
place,
the
cells will
be
trickle-charged as in
'Off'.
lt is
specifically
recommended
that
primary
(dry)
cells are
not
used,
whether
alkaline or other
types.
lf,
however,
they
are used, they
MUST be
removed
before
connecting
the mains
adaptor.
Damage
caused
by
use of dry cells is
not
covered
by the
guarantee.
RANGE
Switch
(2).
This has
three
positions:
'10MHz'selects
the
10MHz range.
Any
signal of sufficient strength
may
be
read from
5Hz to 10MHz
on
this range,
but
see
'Low
Frequency Filter' and
'Trigger
Level' below. The
signal must
be
applied
to Input
A
(7).
