2. INTRODUCTION
This manual describes how the SW Series Super Wash Down Scales work and how to
get the most out of them in terms of performance. Please read this manual completely
before using the scale.
3. FEATURES
The SW Series Super Wash Down Scales have the following features:
Dust-tight and water-tight construction, complying with IP69K.
The weighing platforms and weighing pans are made of stainless steel (SUS304).
The weighing platforms are designed for easy cleaning and not to collect dust.
Three sizes of weighing platform are available.
Employing touch-sensitive switches enabled the display to be covered with a plastic
sheet, resulting in better dust-tight and water-tight performance.
When a switch is touched, the corresponding LED, above that switch, turns on to
indicated that the switch has been touched.
A bright LED display, with a broad viewing angle.
Three types of weight display resolution are available to cover various applications,
1/3,000, 1/6,000 (1/7,500 for some models) and 1/12,000 (or 1/15,000 for some
models). (To be selected in the function settings.)
The counting mode easily counts the number of objects of the same weight.
The comparator mode compares the displayed value (weight value) with the
previously set comparator values and indicates the results by the large and bright
LED display. Five-level and three-level comparators are available.
The optional comparator relay output (OP-03) can output the results as a relay
signal.
Available weighing units are kg (kilogram), g (gram), Ib (pound), oz (ounce), Ib-oz
(pound and ounce) and pcs (pieces for the counting mode).
The optional RS-232C serial interface (OP-03) or optional RS-422/485 serial
interface (OP-04) can transmit the weight value to a printer or personal computer.
The optional sealed lead acid (SAL) battery (OP-02) can be installed, allowing the
scale to be used where an AC power source is not available.

ZERO switch
Zeroes the scale and sets the display to zero. (See below.)
TARE switch
Subtracts the tare (container) weight placed on the weighing pan. (See below.)
In the setting mode, this switch is used to store the setting value and proceed
to the next step.
The ZERO switch will zero the scale if the weight value is within ±2% of the
weighing capacity (kg) around the power-on zero point. The ZERO indicator
turns on. (ZERO operation)
The TARE switch will tare the scale and subtract the weight to zero as a tare
weight when the weight is a plus stable value. In this case the ZERO and NET
indicators turn on. (TARE operation)
When the tare is removed while the tare operation is in progress and the scale
returns to the zero point, the ZERO and NET indicators turn on. In this case
the displayed tare value will be negative.
(Note: In some countries or areas, the ZERO indicator will not turn on
during the TARE operation.)
When the tare is removed while the TARE operation is in progress and the ZERO
operation described above is performed, the tare operation previously done is

8. BASIC OPERATION
8.1. Turning the power ON and OFF
1. Press the ON/OFF switch to turn the power ON.
All the display symbols appear and the scale waits for the weight value to become
stable.
When the optional sealed lead acid (SLA) battery (OP-02) is used:
After all the display symbols appear, the battery capacity status is displayed for
about 1.5 seconds as shown below.
Level Display Battery capacity status
1 “bat ooo” Full capacity
2 “bat _oo”
3 “bat __o”
4 “bat ___” No capacity (Low battery)
At level 3, prepare to recharge the battery.
At level 4, recharge the battery immediately. (Refer to “13.1. Using the OP-02
SLA battery”.)
After the weight value internally becomes stable, the display turns off for a moment,
and then, zero is displayed along with the ZERO indicator (power-on zero).
If the weight value is unstable, “------” is displayed. Check if anything touches
the weighing pan, or if there is a strong draft or vibration. Eliminate the cause of the
error.
The range for power-on zero is within ±50% of the weighing capacity (kg) around
the calibrated zero point.
If the power is turned ON while there is a load beyond this range, “------” is
displayed. Remove the load from the weighing pan.
If the scale is to be turned ON with some item loaded, performing a zero calibration
with the item loaded will allow the scale to turn ON that way. (Refer to “11.
CALIBRATION”.) In this case, make sure that the total weight of the item loaded at
power-on and the object to be weighed is within the weighing capacity.
2. Press and hold the ON/OFF switch to turn the power OFF.
Auto power-off function
The auto power-off function automatically turns the power OFF, if zero is displayed
for approximately 5 minutes.

The ZERO switch will zero the scale if the
weight value is within ±2% of the weighing
capacity (kg) around the power-on zero point. The
ZERO
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. The NET and ZERO indicators turns
on.
(Note: In some countries or areas, the ZERO indicator will not turn on
during the TARE operation.)
Weighing is possible up to the weighing capacity. When a tare is used, weighing is

10. COMPARATOR
Five-level and three-level comparators are available.
The 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.
The 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.
The results are output using LEDs (yellow / green / red).
When the optional comparator relay output (OP-03) is installed, the results are output as
a relay signal.
To use the comparator modes, the function settings “Cp-l” and “Cp” must be
specified.
Using the function setting “Cp-l”, select a comparator mode.
0: five-level comparator mode
1: three-level comparator mode
Using the function setting “Cp”, select comparison conditions.
0: No comparison (comparator mode disabled).
1: To compare all data.
2: To compare all stable data.
3: To compare all data which are more than or equal to +5d, or less than
or equal to -5d.
4: To compare stable data which are more than or equal to +5d, or less
than or equal to -5d.
5: To compare all data which are more than or equal to +5d.
6: To compare stable data which are more than or equal to +5d.
d = minimum display in kg (Refer to “15.1. Specifications”.)
Also in the counting mode, “d” is equal to the minimum display of kg mode.
10.1. The formula to compare
Comparison is performed using the formula listed below and the results are output.

LO limit value = Lower limit value
HI limit value = Upper limit value
The comparator values are common to the weighing and counting mode.
Ignore the decimal point when setting the comparator values.
For example, when the weighing capacity is 6 kg and the setting value is “001000”:
Display mode Limit value Capacity / Minimum display
Normal resolution kg 1.000 kg 6.000 kg / 0.002 kg
High resolution kg 1.000 kg 6.000 kg / 0.001 kg
Maximum resolution kg 0.1000 kg 6.0000 kg / 0.0005 kg
Normal resolution oz 100.0 oz 210.0 oz / 0.1 oz
High resolution oz 10.00 oz 210.00 oz / 0.05 oz
Maximum 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.
Judgment order of comparison is from the top row to the bottom in the comparator
mode tables
In this mode, the entered comparator values are not judged. Even if the upper limit
value is less than the lower limit value, no error will be output.
