3. OPERATIONS
Normal Weighing Mode
1. Power on the scale by pressing the ZERO/ON/OFF key.
2. When the display stabilizes, but it doesn’t show zero, press ZERO/ON/OFF to set a new zero point.
3. Place objects on the scale platform and read the weight on the indicator.
Note: Objects should be placed at the center of the platform. Corner or side loading heavy objects may risk
overloading an individual load cell and damage the scale.
Yes
No
No
4. To change the weight unit of measure, press the UNIT key.
5. To send data to another device via the serial port, press the PRINT/HOLD key.
6. To hold the weight data, press and hold the PRINT/HOLD key for 4 seconds.
7. Power off the scale by pressing and holding the ZERO/ON/OFF key for 4 seconds.
ZERO
If the display dose not shows 0, and there is nothing on the platter, press the ZERO/ON/OFF key to zero the reading.
Zero range: ±20% * full Capacity.
The zero function is unavailable when the displayed reading is out of the zero range and the indicator will show the error
message 0﹉﹉﹉ or 0﹍﹍﹍, meaning the scale is over or under zero range.
Setting a Tare Weight
1. Zero the scale as described above.
2. Place an empty container on the platform, press the TARE key. The display will return to zero, eliminating the weight
of the container. The NET announciator will be lit on the display.
3. Put the material or object to be weighed in the container. The net weight will be displayed.
4. To exit tare mode, remove all weight from the scale. The display will show a negative weight. Press the TARE key to
return the display to zero.

4. Calibration
Note:
(1) Before calibrating the scale, you should prepare standard weights (more than 10% of FS weight) for calibration.
(2) In the following steps, pressing ZERO/ON/OFF will exit calibration.
1.
Move all weight from the scale. Under normal weighing mode, press and hold TARE and ZERO/ON/OFF keys for
more than 4s to enter calibration mode.
2.
The indicator will show “CAL.P0”, the scale will begin to calibrate the zero-point of the scale. Remove all weight from
the scale. Press the TARE key to confirm, or press the ZERO/ON/OFF to exit this mode. After receiving the
reasonable zero-point data, the next step will automatically occur.
3.
When “CAL.P1” is displayed, the scale will be calibrated on second calibration point. xxxxxx kg (or lb) will be displayed.
The default standard weight is 50%FS. Load 5%-100%FS weight on the scale, and use the HOLD or UNIT keys to
input the loaded weight. Press the TARE key to confirm the input, and then the indicator will flash the input standard
weight. After the scale becomes stable it will automatically be directed to next step. If the second point cannot be
calibrated correctly, it will display “CAL.Er” and return back to step2 for re-calibration.
4.
When “CAL.P2”is displayed, the scale will be calibrated on third calibration point. xxxxxx kg (or lb) will be displayed.
The default standard weight is 100% FS. Load 10%-100%FS (this must be equal or larger than the weight from the
second calibration point) weight on the scale. Use the HOLD or UNIT keys to input the standard weight’s value.
Press the TARE key to confirm. The indicator will flash the input weight. If the indicator receives reasonable data, it
will go to next step automatically. If an error occurred, the scale will display “CAL.Er” and return back to step2 for
re-calibration.
5.
When “CAL.P0” is shown again, the scale will calibrate the zero-point again. Remove any weight from the scale, press
the TARE key to confirm; the displayed data will flash. If the indicator receives reasonable data, it will calculate and
store all parameters into EEPROM. Then it will auto-reset, and be directed to weighing mode. If an error occurred in
calibration, the scale will display “CAL.Er” and then it necessary to repeat the procedure from step2.

5. Configuration Parameters Setup
1. When the scale is off, press and hold ZERO/ON/OFF and PRINT/HOLD keys until ‘C0NF’ is shown, which indicates
that the scale is in Configuration parameter setup mode.
2. During setup mode, press the UNIT key to change the flashed digits, and use the HOLD/PRINT key to shift the
flashed position. Press the TARE key to confirm the flashed digits. Press the ZERO/ON/OFF key to exit this mode.

4. More Information for Configuration Parameters:
4.1 The division (d) of scale is determined by C3,C4 and C5 :
If C3=3 (interval is 5), C4=2(decimal point is x.xx), C5=1(unit is lb),
Then C3xC4xC5=5x0.01xlb=0.05lb,
So, d=0.05lb
4.2 The capacity is determined by C1 and d :
If C1=3000, d=0.05lb, then C1xd=3000x0.05lb=150.00lb,
So, the capacity (FS) is 150.00lb
4.3 Operation on C16 :
If you need to recover all configuration and user parameters to their default value, modify the “0” to “1” when
“C16 0” is shown, then press the TARE key to confirm. The indicator will display “dEF.?” and “?” is flashed, press
the TARE key to confirm, then “dEF.?” will flash to indicate recovery processing; “C16 0” will be displayed when
the processing is complete. When the indicator displays “dEF.?” and “?” is flashed, press the ZERO/ON/OFF key
to exit this mode and not to recover parameters.
NOTE: Different setting of the Configuration Parameters can result in the scale having a different performance!
6. User Parameters Setup
1. In normal weighing mode, press UNIT and ZERO/ON/OFF until “USer” is shown to enter in the mode.
2. Press the UNIT key to change the flashed digits, press the HOLD/PRINT key to shift the flashed position. Press
the TARE key to confirm and save the set data and enter next setting. Press the ZERO/ON/OFF key to exit this
