Remove the 4 screws from the lower part of the display pole. 3. Insert the display pole under the base while pulling out the cable into the base and align the cable opening positions of the pole and the base. (See “3” in the illustration.) Do not pull the cable forcibly. Take care not to pinch the cable between the pole and the base.
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. SW type with a display pole has an extra foot at the bottom of the pole. Adjust this foot to touch the floor after adjusting the level of the base. Leveling foot Spirit level The size and shape depends on the scale model. 3. Adjust the display angle as follows.
8. BASIC OPERATION 8.1. Turning the power ON and OFF 1. Press the ON/OFF key 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 (HC-02i) 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 key to select a weighing unit. Each time the UNITS key is pressed, the unit changes as shown below. Ib oz Ib-oz kg or g pcs Using the function setting “Ut-g”, “kg” and “g” can be switched. Ut-g 0 : To display “kg”. Ut-g 1 : To display “g”. Notes • For the SW-60K / 150K, the function setting “Ut-g” is not available and only “kg” is displayed. • Not all the units are available, depending on the area or country. 8.3.
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: High: Maximum: 1/3,000 1/6,000 or 1/7,500 (depending on the weighing capacity) 1/12,000 or 1/15,000 (depending on the weighing capacity The factory setting is the high resolution. Select the resolution that suits your own application in the function setting “re5o”.
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. 1. Press the UNITS Press key to select “pcs”. (“pcs” = pieces) 2. Press the SAMPLE key to enter the sample unit weight storing mode. The numerical value on the left indicates the number of samples. ZERO 3. To change the number of samples, press the PRINT key.
10. COMPARATOR Five-level, three-level and seven-level (portion weighing mode) comparators are available. Each comparator mode compares the weight value against the preset limit values and outputs the results using LEDs (yellow / green / red). When the optional comparator relay output (SW-03) is installed, the results are output as a relay signal. • 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.
10.1. The formula to compare Comparison is performed using the formula listed below and the results are output.
10.2. Entering the comparator values 1. In the weighing mode, press and hold the SAMPLE key to enter the comparator value setting mode. 2. Enter the comparator values using the following keys. UNITS To shift the blinking digit to the right. PRINT To increase the value of the blinking digit by one. SAMPLE To switch the polarity. Each time the key is pressed, “-“ is turned on and off at the leftmost digit. When on, the value is negative. TARE To confirm and store the setting value. 3.
11. AUTO-TARE FUNCTION The SW series has an auto-tare function to be used with the comparator mode enabled. Using this function in check weighing, the scale automatically tares, then displays “OK” for a certain amount of sample and repeats this process for the next weighing. Start with display zero after tare operation. Place or take away objects until the comparison result will show OK.
12. 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: Calibration can not be performed on the Legal for Trade models. 12.1.

14. OPTIONS 14.1. Using the HC-02i 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. The battery life will vary depending on how the scale is used, the ambient temperature and so on. A battery, NP4-6 (6V, 4Ah), manufactured by YUASA, is commercially available.
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 keys. Note: Be sure to connect the RED wire to the positive (+ / RED) terminal and the BLACK wire to the negative (- / BLACK) terminal. Or there is a risk of explosion. 4. Install the battery into the display. 5.
14.2. SW-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 SW-03 is installed, the dust-tight and water-tight performance of the scale will be degraded. SW-03 includes an interface board, two connector cables (7 and 10 pins), two cable glands (for cable diameter 3.5 to 7.0 mm) and two screws (M3x8). 14.2.1.
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. Connect the cables to the external device through the cable gland to the terminal blocks on the interface board. 4.
When connecting to an external device with hardware flow control, communication will be impossible using a cable without RTS and CTS connected. In that case, connect RTS and CTS. This will disable hardware flow control, but will enable communication. • When the connector of an external device is a D-Sub 9-pin connector, pin 7 is RTS and pin 8 is CTS. • When the AX-KO3285-320 cable is used, RTS and CTS are internally connected and the above operation is unnecessary. 14.2.2.
