Measurement
Preparations,
Notes,
and
Considerations
Accuracy
is
given
as
%
full
‐
scale;
therefore
using
the
lowest
range
will
yield
the
best
accuracy.
The
meter’s
display
will
indicate
E02
or
E03
if
the
measured
value
is
below
(E02)
or
above
(E03)
specified
limits
of
the
meter.
If
this
occurs,
please
select
another
range
as
described
in
the
Manual
Range
discussion
in
previous
paragraph.
The
temperature
coefficient
is
fixed
and
cannot
be
adjusted.
The
normalization
(reference)
temperature
is
fixed
(25
o
C);
the
nominal
value
is
correct
for
most
applications.
Rinse
the
probe
with
deionized
or
distilled
water
before
use
to
remove
impurities
that
may
adhere
to
the
electrode.
When
the
meter
has
been
idle
for
a
long
period,
soak
the
electrode
for
at
least
30
minutes
before
use.
When
dipping
the
probe
into
a
sample
solution,
be
sure
to
eliminate
air
bubbles
trapped
in
the
probe’s
slot.
To
remove
air
bubbles,
give
the
probe
a
gentle
stir
while
submerged
in
the
solution.
When
taking
a
measurement,
stir
the
probe
gently
in
the
sample
to
create
a
homogenous
sample.
Allow
a
few
seconds
to
elapse
for
the
probe
and
the
sample
to
reach
temperature
equilibrium.
Ideally,
wait
15
minutes
to
achieve
maximum
accuracy
and
best
temperature
compensation.
The
unit
of
measure
icon
will
flash
on
the
meter’s
display
while
stabilization
is
taking
place
in
measurement
mode.
When
stabilization
is
achieved,
the
meter’s
icon
will
stop
flashing.
Press
the
HOLD
button
to
freeze
a
displayed
reading.
Press
again
to
release
the
display.
Salinity
Measurement
1.
Read
the
Measurement
Preparation
section
above
before
continuing.
2.
Insert
the
electrode
into
the
sample
ensuring
that
the
electrodes
are
completely
submersed.
3.
Slowly
stir
the
solution
with
the
electrode
to
remove
air
bubbles.
4.
The
meter
uses
the
Auto
‐
range
utility
to
find
the
proper
range
and
then
displays
the
salinity
reading
at
the
center
of
the
LCD
with
the
temperature
reading
shown
on
the
lower
LCD
area
in
smaller
digits.
Finishing
a
Measurement
Session
After
a
measurement
session:
Rinse
the
electrode
in
deionized
or
distilled
water
and
store
dry.
Affix
the
protective
cap
over
the
electrode
when
storing.
If
the
unit
is
to
be
left
un
‐
unused
for
long
periods,
remove
and
store
the
batteries
separately.
Automatic
Power
OFF
(Sleep
mode)
The
meter
will
automatically
switch
OFF
after
20
minutes
of
inactivity.
To
disable
the
Sleep
Mode:
With
the
instrument
switched
off,
press
and
hold
the
SET
and
HLD/CAL
buttons
simultaneously
until
the
‘n’
icon
appears
on
the
display.
Release
the
buttons
and
the
meter
will
power
up.
The
meter
will
now
stay
switched
ON
until
the
user
manually
switches
it
OFF.
The
meter
reverts
to
the
‘Sleep
Mode
active’
state
each
time
it
is
powered
down.
