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.

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.

At the zero point, the net weight display shows the tare weight in negative, and the
ZERO◄ and NET◄ indicators turn on.

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 “

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 “

8. COMPARATOR
The scale has three-, five- and seven-level comparators.
Each comparator mode compares the weight value against the preset limit values and
outputs the results using LEDs (yellow / green / red).
Note: When the unit is “lb-oz” or “tl”, this function can not be used.
• Five-level comparator mode:
Uses four comparator values
to compare the weight value
and outputs results in five
levels of LOLO, LO, OK, HI
and HIHI.
• Three-level comparator mode:
Uses two comparator values
(upper and lower limit values)
to compare the weight value
and outputs results in three
levels of LO, OK and HI.
• Seven-level comparator mode (portion weighing mode):
Uses six comparator
values to compare the
weight value and outputs
results in seven levels of
outside the lowest limit,
level 1 (LOLO), level 2
(LO), Level 3 (OK), level
4 (HI), level 5 (HIHI) and

The comparator values are common to the weighing and counting mode.
Ignore the decimal point when setting the comparator values.
Example for SJ-6000WP when the setting value is “001000”:
Normal resolution kg 1.000 kg 6.000 kg / 0.001 kg
High resolution kg 0.1000 kg 6.0000 kg / 0.0005 kg

High resolution oz 10.00 oz 210.00 oz / 0.02 oz
Counting mode 1000 pcs
The comparator values are maintained even if the power is turned OFF.
The scale does not judge magnitude relation among the comparator values.
Even if the wrong values are set, no error will be shown.

The SJ-WP series has an auto-tare function to be used with the comparator mode
enabled. If the weight values are in the OK range of comparator limits and stable for a
preset period of time, the scale will automatic 1 ally tare the weight and show zero.
In some countries or areas, the auto-tare function can not be used on the Legal for Trade
models and the selection in the function settings “at”, “

10. CALIBRATION
Adjusts the scale for accurate weighing.
Calibrate the scale in the following cases.
When the scale is first installed.
When the scale has been moved.
When the ambient environment has changed.
For regular calibration.
Note: The Legal for Trade models can not be re-calibrated if they have been
sealed.
10.1. Calibration mode
The calibration mode has the following three functions.
• Gravity acceleration correction
• Calibration using a weight
• Restoring the factory set values
How to enter the calibration mode
Method 1:
1. Make sure that the scale is in the weighing mode.
2. Touch and hold the SAMPLE switch until the gravity acceleration value (in this
Note: The above operation is disabled for the Legal for Trade models.
Method 2:
example, “9.7985”) appears and release the switch.
1. Make sure that the scale is in the
weighing mode.
2. Loosen the two screws on the switch
cover and open the switch cover. The
calibration (CAL) switch is located inside.
3. Press the CAL switch. The scale

10.2. Gravity acceleration correction
When the scale is first used or has been moved to another location, it should be
calibrated using a calibration weight.
But if a calibration weight is not available, the gravity acceleration correction will
compensate the scale. Change the gravity acceleration value stored in the scale to the
value of the area where the scale will be used. Refer to the gravity acceleration map at
the end of this manual.
Note: Gravity acceleration correction is not required when the scale will be
calibrated using a calibration weight at the place where it is to be used.
1. Refer to “10.1. Calibration mode” to enter the calibration
mode. The gravity acceleration value is displayed.
2. Tap the TARE switch to enter the gravity
acceleration value setting mode.
3. Change the displayed value using the following switches.
UNITS To shift the blinking digit to the right.
SAMPLE To increase the value of the blinking
digit by one.
4. Tap the TARE switch. The display shows “end” and
returns to the newly stored gravity acceleration value.

12. MAINTENANCE
12.1. Notes on maintenance
Do not disassemble the scale. Contact your local A&D dealer if the scale needs
service or repair.
Use the original packaging for transportation.
Do not use organic solvents to clean the scale. Use a warm lint free cloth
dampened with a mild detergent.
Calibrate the scale periodically to maintain the weighing accuracy.
12.2. Error codes
Overload error
Indicates that an object beyond the weighing capacity
has been placed on the weighing pan.
Underload error
Power-on zero error
Unit weight error
CAL error
Low battery
Other
Remove the object from the weighing pan.
Indicates that the weight sensor receives a strong
upward force. Check if there is anything sandwiched
around the weighing pan. There is a possibility that the
weight sensor or internal circuit may have a problem.
Indicates that the power is turned on with a load beyond
the power-on zero range, or the weight value too
unstable to perform power-on zero. Remove the load, or
check if there is wind, vibration or anything touching the
weighing pan.
Indicates that total weight of samples is too light to set
the unit weight in the counting mode. Increase the
number of samples and try again
Indicates that the calibration procedure is canceled
because the calibration weight is too light.
Check that the weighing pan is installed properly and the
mass of the calibration weight is correct.
Indicates that the batteries have run out.
Replace them with new batteries.
There may be an internal malfunction.
(∗ indicates an error number.)
Note: If the error persists or other errors occur, contact your local A&D dealer.
