ZERO ◄ Turns on when zero is displayed. Comparator LEDs Weighing units ＊ Turns on when the comparator results are displayed. “Ib”, “oz”, “ozt” , “Ib-oz” , “tI-s” , “tI-h” , “tI-t” , “t” , “pcs” , “N” , “g” and “kg” are available. A selected unit is displayed. Turns on while a switch is touched.
4.2. Operations and functions of switches Switch Description When the scale is turned off: Touch the switch to turn ON the scale. The scale will be automatically set to zero (power-on zero). When the scale is turned on: Touch and hold the switch to trun OFF the scale. Tap the switch to ZERO the scale and display zero. During measurement: Touch and hold the switch to proceed to the calibration mode.
5. OPERATION 5.1. Basic weighing operation 1. Touch the switch to turn the power ON. Container All the symbols except the comparator LEDs are displayed. When the weight values becomes stable, the display turns off for a moment and Weighing pan displays zero (power-on zero) with the weighing unit used last before turning off. Tap 2. Select a weighing unit using the UNITS switch. 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.
The TARE switch will tare the scale and subtract the weight to zero as a tare weight when the weight is a plus value. In this case the ZERO◄ and NET◄ indicators turn on. (TARE operation) At the zero point, the net weight display shows the tare weight in negative, and the ZERO◄ and NET◄ indicators turn on. (Note: In some countries or areas, the ZERO ◄ indicator will not turn on while the scale is tared.) When the scale is tared, weighing range for net loads is reduced by the amount of the tare weight.
6. SELECTING A WEIGHING UNIT 6.1. Storing the weighing unit 1. Touch the ON/OFF switch while touching and holding the TARE switch in order to display in the function setting mode. 2. Tap the UNITS switch to display . 3. Tap the SAMPLE switch to display a unit. Tap the TARE switch to activate or deactivate the unit. The indicator is displayed for each active unit. 4. Repeat step 3 for other units. 5. Tap the UNITS switch to move to the next function item when finishing the selection. 6.
7. 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. Tap the UNITS switch to se lect “pcs”. (“pcs” = pieces) Tap 2. Tap the SAMPLE switch to enter the sample unit weight storing mode. The numerical value on the left indicates the number of samples. Tap 3.
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.
6: To compare stable data which are ≥ +5d. d = minimum display in kg (Refer to “13. SPECIFICATIONS”.) In the counting mode, “d” is equal to the minimum weight display of kg mode. 8.1. The formula to compare Comparison is performed using the formula listed below and the results are output.
Seven-level comparator mode (portion weighing mode) Results Comparison formula LED display Displayed value < Level 1 lower limit, or “-e” ( No LEDs on) Level 1 Level 2 LOLO (Level 1) lower limit ≤ Displayed value < lower limit ( Red LED on) None Level 2 Level 3 ≤ Displayed value < lower limit lower limit ( Yellow LED on) Level 3 Level 3 OK (Level 3) lower limit ≤ Displayed value ≤ upper limit ( Green LED on) Level 3 Level 4 HI (Level 4) upper limit < Displayed value ≤ upper limit ( Yellow LED on
8.2. Entering the comparator values 1. In the weighing mode, touch and hold the value setting mode. UNITS switch to enter the comparator 2. Enter the comparator values using the following switches. UNITS To shift the blinking digit to the right. SAMPLE To increase the value of the blinking digit by one. TARE To store the setting value and to go to the next limit setting or “end”. The minus sign can be set at the next digit of the least significant digit.
9. AUTO-TARE 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”, “at-t” and “at-f” is not available. To use the auto-tare function, set the function settings below.
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.
