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. 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”. Note: For the SW-60K / 150K, the function setting “Ut-g” is not available and only “kg” is displayed. 8.3. Basic weighing operation 1. Press the ON/OFF switch to turn the power ON.
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 by 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 switch to select “pcs”. (“pcs” = pieces) ZERO 2. Press the SAMPLE switch to enter the sample unit weight storing mode. The numerical value on the left indicates the number of samples. Press ZERO 3.
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).
Three-level comparator mode Results LO Comparison formula Displayed value < LO limit value (Or over in the negative value) LED display OK LO limit value ≤ Displayed value ≤ HI limit value HI HI limit value < Displayed value (Or over in the positive value) ( Red LED on) ( Green LED on)） ( Red LED on) 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.
10.2. Entering the comparator values 1. In the weighing mode, press and hold the value setting mode. SAMPLE switch to enter the comparator 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. SAMPLE To switch the polarity. Each time the switch 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. 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. But if a calibration weight is not available, the gravity acceleration correction will compensate the scale.
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. Change the function setting “poff” or place something on the weighing pan to disable the auto power-off function. Make sure that the scale is in the weighing mode (displaying “kg” (“g”), “lb”, “oz” or “pcs”).
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”). 1. Press and hold the TARE switch until the gravity acceleration value appears, and release the switch. Press and hold (more than 4 seconds) switch twice to Release Press twice 3.
