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.
4. PRECAUTIONS 4.1. Installing the scale Caution • Ground the scale so that the user will not be subject to an electric shock. • Do not handle the AC power cable with wet hands. • The AC plug is not water-resistant. Use an electrical outlet located at a place where the plug will not get wet.
5. UNPACKING When unpacking, check whether all of the following items are included: Instruction manual SW series scale The scale components are different depending on the type of scale.

7. SETTING UP 7.1. Attaching the display pole to the base Lower part of SW-M / L series with a display pole the display pole 1. Remove the weighing pan from the base. 2. Remove the 4 screws from the lower part of the display pole.
7.2. Installing the scale 1. Select the place for installing the scale. Refer to “4. PRECAUTIONS”. 2. Adjust the level of the base, using the spirit level and leveling feet. Confirm that the bubble is in the center of the level.
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.
8.2. Selecting a weighing unit In the weighing mode, press the UNITS switch to select a weighing unit. Each time the UNITS switch is pressed, the unit changes as shown below. kg or g Ib-oz Ut-g Using the function setting “ ”, “kg”...
8.4. Weight display resolution The weight display resolution is a ratio of the minimum display to the weighing capacity. The SW series has three types of weight display resolution, as shown below. Normal: 1/3,000 High: 1/6,000 or 1/7,500 (depending on the weighing capacity) Maximum 1/12,000 or 1/15,000 (depending on the weighing capacity The factory setting is the high resolution.
9. COUNTING MODE Determines a unit weight (the weight of one piece) from a known sample quantity, and calculates how many pieces are on the weighing pan using the unit weight. The unit weight is maintained even if the power is turned OFF. Press 1.
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.

10.2. Entering the comparator values 1. In the weighing mode, press and hold the SAMPLE switch to enter the comparator value setting mode. 2. Enter the comparator values using the following switches. UNITS To shift the blinking digit to the right. PRINT To increase the value of the blinking digit by one.
11. 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. 11.1. Gravity acceleration correction When the scale is first used or has been moved to another location, it should be calibrated using a calibration weight.
11.2. Calibration using a weight Prepare a weight, preferably a weight with the same value as the weighing capacity of the scale to be calibrated. Note that the calibration weight value can be changed. 1. Turn the power ON and warm up the scale for at least half an hour. poff Change the function setting “...
11.3. Restoring the factory set values If the gravity acceleration value or calibration weight value is changed unintentionally, restore those values to the factory setting values, as follows. Make sure that the scale is in the weighing mode (displaying “kg” (“g”), “lb”, “oz” or “pcs”). Press and hold 1.
12. FUNCTIONS The scale has function settings to specify the scale performance. The parameters set in the function settings are maintained even if the power is turned OFF. Parameter Item While holding down, press 12.1. Setting the parameters 1. Turn the power OFF. 2.

13. OPTIONS 13.1. Using the OP-02 SLA battery The scale can be operated with a sealed lead acid (SLA) battery, available as an option. The scale (with no other options) can be operated continuously for about 90 hours with a fully charged battery. The battery will take about 15 hours to be fully charged.
1. Disconnect the AC power cable from the electrical outlet. 2. Loosen the M4 screws and remove the rear cover of the display. Note: Take care not to drop the display. 3. Connect the wires inside the display to the battery with much care so that nothing touches the switches.
13.2. OP-03 RS-232C / RELAY OUTPUT This interface allows the SW scale to be connected to an AD-8121 printer or a personal computer, and the relay outputs for comparator results are also available. When OP-03 is installed, the dust-tight and water-tight performance of the scale will be degraded.
1. Disconnect the AC power cable from the electrical outlet. When the battery is installed, make sure that the scale is turned OFF. 2. Loosen the M4 screws and remove the rear cover of the display. Note: Take care not to drop the display. 3.
