CALIBRATION
Calibration may be required when it is initially installed, if the scale is moved to a
substantial distance.
Calibration:
Single segment calibration (recommended):
1. Turn on the scale and then turn it off.
2. Press and hold [ZERO] and then turn on the scale, LCD will show SCALE on
first line, CAL-0 (flashed) on the second line and AD value on the third line.
3. Press [SAMPLE/UNIT] to select calibration unit kg or lb.
4. After the stable A/D value is displayed, press [ZERO] to calibrate ZERO, after
2 or 3 seconds, the second will show 0.
5. Set calibration weight through input 0 to 9 and then place the calibration weight
you had set, Press [ZERO] to calibrate, after the stable indicator light, press
[ZERO] key, the second line of display will show 00000 and now calibration is
finished.
6. Turn off the power, then turn on the power again, place some weight on the
platform to make sure whether weighing is correct, if not, repeat steps 1-6.
Linearity calibration (for scale technician or factory use):
1. Turn on the scale and then turn it off.
2. Press and hold [TARE] and then turn on the scale, LCD will show LINE
on first row,CAL-0 (flashed) on the second line and AD value on the third line.
3. When the AD value is stable, press [ZERO] to calibrate ZERO, after 2 or 3
seconds, the second line will show 1.0000.
4. Place 1kg weight on the platform , and press [ZERO] when the stable A/D value
is displayed, after 2 or 3 seconds, the display will show 2.0000.
5. Place 2kg weight on the platform , and press [ZERO] when the stable A/D value
is displayed, after 2 or 3 seconds, the display will show3.0000.
6. Place 3kg weight on the platform , and press [ZERO] when the stable A/D value
is displayed, after 2 or 3 seconds, the display will show0.0000 and now calibration is
finished.
7. Turn off the power, then turn on the power again, place some weight on the
platform to make sure whether weighing is correct, if not, repeat steps 1-6.

17. [MC] KEY MEMORY CANCEL is used for canceling the data in memory.
18. [TOTAL] KEY is used for switching normal counting and recalling memory data.
19. [SAMPLE/UNIT] (lb/Kg). Press the key to selected weight unit. Once the unit is
selected, the selected unit indicates the different calibration and weighing unit.
Ⅲ. OPERATION:
TARE
Clearing Tare weight:
Place the empty container on the platter. Press [TARE] key. The WEIGHT display shows
0.00000.
When the container is removed from the platter, the WEIGHT display will show with minus
weight value which is the weight of the container.
Clearing the previous tare value:
Remove weight from the platter then press [TARE] key so that the Tare indicator turns off and
WEIGHT display returns to Zero.
SAMPLE SETTING: There are two sample setting methods:
Number setting: (In case of counting the unknown unit weight)
Place the pre-counted X number of samples on the platter, total weight is displayed. Set the X
number of samples through numeric keys and press SAMPLE/UNIT key. UNIT WEIGHT on
display shows the average piece weight of the samples.TOTAL (pcs) on display will show
the number of unit on the scale, add in more samples and it will show the total number of
pieces.
Unit weight setting: (In case unit weight is known)
Place samples on the scale. Key in the average piece weight using the numeric keypad.
Press UNIT WEIGHT on the keypad. The total number of pieces will be shown on the TOTAL
(pcs). Add in more units to be counted. Press CE key to clear previous setting.
c. Press [CE] key for cancel the previous unit weight and sample setting.
ALARM FUNCTION: To avoid counting errors, this scale has an useful alarm function to inform
operator of counting error in case of low sample size or low sample weight.
