CAUTION
.. The prism surface in the sample chamber is the
most sensitive part
of the unit.
Be very careful not to scratch the prism
surface, and be sure to use soft tissue paper
when wiping
the prism surface.
.. Except for the measurement of electrolyte
solution
of a lead acid battery, do not use the
SBS 2002 for the measurement ofother
electrolyte solutions like alkaline batteries, etc.
.. Electrolyte contains sulfuric acid, which is a
poison.
If skin and clothing get in contact with
it,
it may cause burn; if it gets in the eye, it
may cause blindness. Therefore, always wear
protective glasses and rubber gloves.
If
electrolyte is splashed on to skin or clothes,
flush with sufficient water; and especially, if it
gets into the eye, flush with
dean water for 15
minutes and get prompt medical attention.
,
TEMPERATURE
In case you measure the electrolyte which has
a big difference between ambient temperature,
pay attention to the following points:
The
unit compentsates for temperature
atuomatically according to the temperature
detected
at the prism in the sample chamber. If
the sample temperature, is different from the
prism temperature, wait for 3 seconds for
every
2°F difference between these tempera-
tures before pressing the start switch. (Wait for
some time before pressing the start switch if
any difference between these temperatures is
suspected.)
Do not leave the
Unit under direct
sunshine,
Never splash
waler on the Unit.
pp
~~~r
Never Ie! the Unit fall orgive
shocks to the Unit.
Never clean the Unit using a
petroleum solvent.

Do not leave the Unit
close to a heatsource.
When the body gets wet.
wipe off the moisture
with dry cloth.
Be sure not to have
leakages at the Nozzle
or the Sample Chamber.

6. MAI NT E NAN ( E
• After measurement, suck and drain distilled water or city water several
times to clean the Sample Chamber, and drain the water well before
storing.
• Do not store the SBS 2002 in a humid place or a place in direct
sunlight.
• The body of the tester is made of plastics, never use solvents ( thinner,
benzine, gasoline, etc.) on the tester.
• Never splash water on the unit.
7. EXPLANATION OF ERROR MESSAGES
The SBS 2002 gives an error indication when something is wrong with
your operation. Error indications that may appear on the
LCD Panel are
explained below.
~ M MA" Zero-setting error
• This error indication appears when zero-setting is attempted on air
without water in
the sample chamber.
• This error indication appears also when zero-setting is attempted with
ordinary sample in the sample chamber.
Note: This error may not occur when the concentration 0/ sample is low
(close to that o/water). and it is necessary to make sure that the liquid is
water in attempting a zero-setting.
• This error indication may also appear when the prism surface is dirty.
If this
is suspected, remove two screws of the sample chamber, pull up
the acrylic cover
and clean the rrism surface well with a tissue paper
orsomething-
~ MUl" Sompling error
This error appears when measurement is made while the sample is not
covering the sample chamber
or while the sample is incompletely
covering the sample possibly due to inclusion ofbubbles.
~ MHHH" Ronge-over error
• This error indication appears at if the sample is out ofthe range of the
SBS 2002.

3. INSERTION OF DRY (ELL BATTERY
~ 1. Open the cover ofthe battery inserting port with a screw driver.
~ 2. Install the battery with proper polarity in the battery inserting port.
~ 3. When the battery is installed in the battery inserting port, close the
cover
and lock it.
Note: The electric circuit 0/ the SBS 2002 turns on once a battery is
installed, Thus, the SBS 2002 does not have a power switch. Depress Start
switch for 2 seconds
and the unit will shut off.
Ifthere is no plan to use the unit for more than a month, keep the
battery removed from the unit.
Note: Use 9v alkaline batteries for maximum service life. Alkaline cells offer
about
2000 uses.

4. ZERO SETTING (CALIBRATION)
.... 1. Remove the cap of the nozzle.
.... 2. Dip the tip of the nozzle in water, and then squeeze and release the
tube pump. The
water is sucked into the sample chamber in this
process.
.... 3. Confirm that the sample chamber has been filled with water. If
bubbles are still in the sample chamber, operate the tube pump again
to suck water to fill the sample chamber.
.... 4. Press the ZERO setting switch."000" will blink three times, and ''000''
will be displayed on the liquid crystal display.
PRESS
.... 5. Now, the zero-setting is over. Take the nozzle out of the water and
squeeze the tube pump to drain the water from the sample chamber.
Claibration
of unit is done by using water and pushing zero switch.
Leave the
SBS 2002 at the place of measurement for some time before
making measurement
so that the temperature oftheSBS 2002 is
sufficiently close
to the ambient temperature.
The zero-setting status remains
as it is until the voltage of the battery
becomes too low
or the battery itself is removed.
Zero-setting can be made anytime. When zero-setting is made again, the
new zero-setting status replaces the previous status.
It is desirable to use distilled water for zero-setting. City water may also
be used because the impurity level is usually as small as 0.01%.
Leave the distilled water at the place of measurement for some time
before zero setting
SO that it's temperature is close to the ambient
temperature.

5. MEASUREMENT OF SAMPLE
.... 1. Press the SELECT switch to move the triangle mark to a desired
measurement item
on the display. The mark moves to the next item
every time you press the
SELECT switch. You may measure either
specific gravity
or temperature.
.... 2. Dip the tip of the nozzle in the sample, and squeezp and release the
tube pump to suck the sample electrolyte into the sample
chamber.
.... 3. Press the START switch. The triangle mark blinks three times, and the
result
of measurement is displayed on the liquid crystal display.
.... 4. Squeeze and release the tube pump to drain the sample electrolyte.
Then move
to the next cell and repeat steps 2 and 3. The total time to
test a cell should be 3-5 seconds.
.... 5. The display value remains on the LCD Panel for 5 minutes if left alone.
.... 6. Keep the START switch pressed for more than 2 seconds to switch the
unit off.
.... 7. Squeeze and release the tube pump several times to drain the sample
electrolyte.
If YQU are storing the SBS 2002, fill the chamber with
water several times by pressing and depressing tube pump, to flush
sample chamber.
Measured result may
not be correct ifdirect sunshine falls on the sample
chamber. Face your back to
the sun or cover the sample chamber with
your hand
at measurement.
If it is difficult to remove the sample liquid from the nozzle by operating
the tube pump, apply a tissue paper to
the tip of the nozzle, and squeeze
it out slowly.
Note: The small amount of sample electrolyte remaining in the nozzle will
have little affect on consecutive measurements.
