1. SAFETY PRECAUTIONS
All safety messages are identified by the following, “
of ANSI Z535.4 (American National Standard Institute: Product Safety Signs
and Labels). The meanings are as follows:

WARNING
CAUTION
This manual is subject to change without notice at any time to improve the
product.
Product specifications are subject to change without any obligation on the part
of the manufacturer.
When using the SJ-WP, the following safety precautions should always be
followed.
WARNING
CAUTION Avoid installing the scale in direct sunlight, which may cause discoloration

CAUTION
”,
Do not mix battery types, or new and old batteries. Replace with all new
batteries at the same time.
If the scale is not to be used for a long period of time, remove all batteries
from the battery compartment to avoid leakage.
Avoid overloading the scale.
Avoid using the weighing platform to move the scale, as that could cause
damage to the scale.
Avoid chemical solvents. Clean the scale with water.

2. Remove all the old batteries from the
battery compartment.
3. Install six new batteries properly
according to the + and - indicators of
polarity in the battery compartment.
4. Close the battery cover, and tighten the
screws for securing the battery cover.

3.2. Setting up the scale
CAUTION Avoid installing the scale in direct sunlight, that may cause
discoloration or malfunctions. Place your SJ-WP on a firm weighing
table so that the scale is level. The scale will not perform accurately
when it is not level.
Place the scale on a firm surface and adjust the feet so that the bubble of the
sprit level is in the center of the circle.

5. OPERATION
5.1. Basic weighing operation
1. Touch the switch to turn the power ON.
All the symbols except the comparator LEDs are
displayed. When the weight values becomes
stable, the display turns off for a moment and
displays zero (power-on zero) with the weighing
unit used last before turning off.
2. Select a weighing unit using the UNITS switch.
See “6. SELECTING A WEIGHING UNIT” in
detail.
3. When the display doesn’t show zero, tap the
switch to set the display to zero.
4. When using a tare (container), place the
container on the weighing pan, and tap the
TARE switch to set the display to zero.
5. Place the object to be weighed on the weighing
pan or in the container, and wait for the STABLE
indicator to turn on and read the value.
6. Remove the object from the weighing pan.

5.2. Notes about operations
Power-on zero
If the weight is unstable at power ON, the scale displays “
touches the weighing pan, or check if there is strong wind or vibration.
The range for power-on zero is within ±50% (±10% for Legal for Trade models) of
the weighing capacity (kg) at the calibrated zero point. If the scale is powered on
with a load beyond this range, the scale displays “

indicator turns on.
The TARE switch will tare the scale and subtract the weight to zero as a tare
weight when the weight is a plus value. In this case the ZERO◄ and NET◄
indicators turn on. (TARE operation)
At the zero point, the net weight display shows the tare weight in negative, and the
ZERO◄ and NET◄ indicators turn on.
(Note: In some countries or areas, the ZERO
while the scale is tared.)
When the scale is tared, weighing range for net loads is reduced by the amount of
the tare weight.
When the ZERO operation is performed in the net weight display, the tare operation
previously done is cleared and the NET◄ indicator turns off.
(Note: In some countries or areas, the ZERO operation will not clear the TARE
operation. Tap the TARE switch after zeroing the scale with nothing
on the weighing pan.)
Auto power-off function
If no switch is touched or tapped and the stable indicator is displayed for a certain
period of time, the scale will automatically turn off. See the function setting “
to set the elapsed time to turn off.
When “ e” or “-e” is displayed (refer to “12.2. Error codes”), the auto power-off
function is enabled.
LCD backlight
The LCD backlight is controlled by the functions “

5.3. Weight display resolution
The weight display resolution is a ratio of the minimum display to the weighing
capacity.
The SJ-WP series has four types of weight display resolution, as shown below.
Low: 1/3,000
Normal: 1/6,000 or 1/7,500 (depending on the weighing capacity)
High: 1/12,000 or 1/15,000 (depending on the weighing capacity)
Maximum: 1/30,000
The factory setting is the normal resolution. Select the resolution according to your
own application in the function setting “
For details about the minimum display and the weighing capacity, refer to “13.
SPECIFICATIONS”.
The weight display resolution of the Legal for Trade models is fixed. The selection in
