CAUTION
Failure
to
disconnect
the
detector
from
the
instrument
before
tuming
it
on
can
damage
the
detector
if
the
high
voltage
is
not
set
properly
for the
particular
detector.
Instructions
for
checking
and
setting
the
high
voltage
can
be
found
in
section
ILE.5.
When
you
are
ready
to
connect
the
detector,
verify
that
you
have
the
proper
cable.
It
should
have
a
MHV
connector
on
one
end
which
mates
to
the
ESP-1
and
a
connector
on
the
other
end
to
mate
with
the
detector.
Refer
to
the
ESP-1
catalog
sheet
for
the
proper
cable
to
use
with
the
specific
detector.
The
cable
number
is
printed
somewhere
along
the
length
of
the
cable.
The
MHV
end
of
the
cable
connector
typically
has
white
insulation
in
the
center
which
extends
slightly
beyond
the
end
of
the
metal
portion
of
the
connector.
In
contrast,
a
BNC
cable
connector
typically
has
the
insulation
flush
with
the
connector
end.
To
connect
the
cable,
rotate
the
connector
clockwise.
Turn the Instrument ON and OFF
Press
the
ON/OFF
switch
to
turn
the
instrument
on.
The
same
switch
will
have
to
be
pressed
to
turn
the
instrument
off.
When
the
instrument
is
turned
on,
the
display
should
indicate
a
numerical
value
on
the
lower
line
and
a
bar
graph
on
the
upper
line.
The
bar
graph
may
be
off-scale,
so
press
the
RESET
button
to
get
її
back
on
scale.
The
ESP-1
is
in
its
Rate
Meter
Mode.
Refer
to
section
П.С.
for
more
information
on
the
displayed
information.
If
the
instrument
has
been
properly
calibrated
and
is
connected
to
a
detector,
it
is
ready
to
use.
Refer
to
section
ILE.
for
instructions
on
how
to
view
and
change
the
calibration
parameters.
A
quick
check
to
determine
that
the
instrument
is
functioning
is
to
compare
the
numerical
value
being
displayed
to
the
background
radiation
level.
If
they
are
close,
then
the
instrument
is
operating
and
ready
to
use.
Remember
that
normal
statistical
fluctuations
can
cause
relatively
large
changes
in
the
displayed
reading
at
low
levels.
Press
the
SPKR
button
and
you
should
hear
a
click
corresponding
to
each
detector
event.
If
this
is
not
the
case,
the
speaker
rate
switch
could
be
in
the
wrong
position.
Refer
to
section
ΠΙ.Α.2.
Determine
Low
Battery
Condition
and
Battery
Replacement
Examine
the
first
character
space
in
the
display
(upper
left
hand
comer).
If
it
is
blinking,
the
batteries
are
low
and
need
replacing.
The
ESP-1
uses
six
"C"
cell
batteries.
The
instrument
automatically
turns
itself
off
two
hours
after
the
low
battery
condition
signal
is
given.
The
ESP-1
can
be
turned
back
on
after
it
turns
off,
but
will
tum
itself
off
again
after
two
hours.
To
change
batteries,
remove
the
large
screw
in
the
bottom
of
the
case,
and
carefully
remove
the
case
bottom
while
being
careful
not
to
disconnect
the
grounding
wire
which
is
connected
to
the
bottom
of
the
case.
Replace
the
batteries
while
being
careful
to
orient
