Eberline ESP-1 - Page 55

(8) At this point no further adjustment is necessary. А few linearity readings at fields in
between the "СС" and "DT" settings would be an added verification of correct
detector/instrument operation. Increasing the radiation field above the "DT" set point, will
eventually cause an over-range alarm. This is useful in determining the ° upper range limit
of that particular detector and instrument combination.
NOTE
The instrument may be rough calibrated by adjusting to
nominal values in table. For detectors for which nominal
values are not specified, the user may determine his own
nominal values for ease and/or speed of the calibration
process.
B. PREVENTIVE MAINTENANCE
5-6
1.
Periodic Maintenance
Because
of
the
simplicity
of
the
ESP-1,
periodic
maintenance
is
neither
time
consuming
nor
overly
frequent.
a.
b.
Install fresh batteries at least once per year.
Remove
the
bottom
cover
and
the
side
access
and
blow
out
the
inside
with
clean,
dry,
low-pressure
air
once
a
year.
Keep the outside of the case clean.
Open
the
bottom
and
side
accesses
only
when
calibration,
maintenance,
or
battery
change
are
necessary.
Battery Replacement
a. Tum
the
instrument
off.
If
the
ESP-1
is
placed
face
down,
exercise
caution
with
the
push
buttons
to
prevent
accidentally
turning
the
instrument
on.
Approximately
20
minutes
are
available
for
battery
change
with
the
ESP-1
turned
off.
Remove
the
large
screw
in
the
bottom
cover.
Remove the bottom cover.
Dispose of the expended batteries.
CAUTION
Many
of
Eberline's
instruments
contain
alkaline,
carbon,
lead,
nickel-cadmium
or
lithium
batteries.
All
batteries
contain
small
amounts
of
heavy
metals
and
other
hazardous
materials
and
must
be
handled
and
disposed
of
properly.
