INTRODUCTION & INSTALLATION
• Risk of Electrical Shock: Disconnect all power sources before making cable
connections to the scale platform or indicator.
• For use in dry environments only.
• Do not operate in hazardous areas.
• Read and understand all operating instructions before using this product. Keep
this manual for future reference.
• Record the weight shortly after placing a load on the platform. After extended
periods, the load cell’s output signal may result in a less accurate reading.
• Place the scale on a hard, flat, and level surface before using.
• Avoid extended exposure to extreme heat or cold. Optimum operation is at
normal room temperature. See operating temperature range in the specifications
table. Allow the scale to acclimate to room temperature before using.
• Allow sufficient warm up time. Turn the scale on and allow up to 2 minutes for
internal components to stabilize before weighing.
• Electronic scales are precision instruments. Do not operate near cell phones,
radios, computers or other electronic devices that emit radio frequencies that
may cause unstable readings.
• Avoid using in heavy vibration or heavy airflow conditions.

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.
NORMAL WEIGHING MODE

OPERATIONS
ZERO
• If the display does not show 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
HOLD FUNCTION
COUNTING
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 TARE
indicator 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.

CALIBRATION
Note:
• Before calibrating the scale, you should prepare standard weights
(more than 25% of FS weight) for calibration.
• 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-?”, which means the scale is ready for calibration.
Press the TARE key to confirm and continue into calibration mode.
3. When “CAL.P0” is displayed, 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.
4. When “CAL.P1” is displayed, the scale will be calibrated on second calibration
point. The default standard weight is 100%FS. Load 12.5%-100%FS weight

Press the TARE key to confirm the input, and then the indicator will flash
the input standard weight. After the scale becomes stable, the indicator
will automatically be directed to next step. If the second point cannot be
calibrated correctly, it will display “CAL.Er” and return back to step3 for re-
calibration.
5. When “CAL.P2”is displayed, the scale will be calibrated on third calibration
point. Load 25%-100%FS (must be equal or larger than the weight from the
CAL.P1) weight on the scale. other operations same as step 4.
6. When “CAL.P3”is displayed, the scale will be calibrated on fourth calibration
point. Load 50% -100%FS ( must be equal or larger than the weight from the
CAL.P2) weight on the scale. other operations same as step 4.
7. 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. If the
indicator receives reasonable data, it will calculate and store all parameters
into EEPROM. Then it will auto-reset, and back to weighing mode. If an error
occurred in calibration, the scale will display “CAL.Er” and then it necessary to
repeat the calibration.
