General and Safety Information

INTRODUCTION and 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

Place the scale on a hard, flat, and level surface before using.

may

result in a less accurate reading.

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.

3. OPERATIONS

Normal Weighing Mode

1. Power on the scale by pressing the ZERO/ON/OFF k ey.

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

4. To change the weight unit of measure, press and hold the UNIT/HOLD key for 4 seconds.

5. 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 0ˉ ˉ ˉ ˉ, 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 TARE 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.

Hold Function

The Hold function is being used if you like to hold the results at the display after the weight/load has been removed from

the scale.

1. Press HOLD key while scale is under load.

2. “HOLD” announciator is being displayed at the screen.

3. The weight remains saved in the display after unloading the scale.

4. For deactivation of the Hold function, press again the UNIT/HOLD key.

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-?”, 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. 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 UNIT/HOLD

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 and receives the ADC’s data corresponding to the standard

weights, and if the data is reasonable and acceptable, 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. 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 UNIT/HOLD 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 step3 for re-calibration.

6. 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

step3.

5. View ADC Code or Power Voltage

1. In normal weighing mode, press and hold UNIT/HOLD , TARE and ZERO/ON/OFF keys until “code” is shown,

which means the indicator is working under display inner code mode. In this mode, you can examine the inner

working voltage, the stability of weighing system, the variety value of A/D data as per the loaded weight.

NOTE:

1) The increment of ADC code for FS weight must be larger or equal to 2 times of selected display division;

otherwise, the calibration cannot be properly completed. E.g. the display division is 0.1kg. Load 100kg

standard weight on the platform, the increment of A/D code is at least 2x 100kg/0.1kg= 2x1000=2000. In

this case, the scale can be calibrated. Otherwise, smaller division need to be chosen.

2) The data should be stable; otherwise, the calibration cannot properly complete.

2. In this mode, you can calculate the proper ADC data at zero point by examining the A/D data for loaded weight. If

the ADC increase for full capacity is NFS, the power-on zero range is set to Zp% FS and zero key range is set to

Zk% FS. Then the proper ADC data of zero point is larger than (Zp%+ Zk%) x NFS.

3. ADC increase for full capacity (NFS) can be calculated by: Load the weight W on the platform, and the ADC increase

for W weight is Nw. The ADC increase for full capacity WFS is (NFS)= (Nw)x (WFS)/W .

Negative value may be displayed because of error connect of loadcell or error position of the zero-point

potentiometer on PCB; however, the software only deals with positive value. So, is you are the position of zero-point

potentiometer is error; adjust potentiometer’s position to make the ADC data will be positive value and larger than

(Zp%+ Zk%) x NFS. Normally the indicator is factory-calibrated, and end users do not need this operation.

Below is the drawing of position of the zero-point potentiometer on PCB for conference, decrease ADC data by

rotating clockwise, and increase ADC data by rotating counter-clockwise.

4. Press the UNIT/HOLD key to select displaying weight inner code or input the inner working voltage value. When

“Ux.xx” is displayed, the display digit is voltage value, and the unit is V. The proper working power voltage is

between 5V to 8 V.

5. Press the TARE key to display filtered or un-filtered weight A/D data; when is on, the data is filtered.

6. Press the ZERO/ON/OFF key to exit this mode and return to normal weighing mode.

6. Configuration Parameters Setup

1. When the scale is off, press and hold ZERO/ON/OFF and UNIT/HOLD keys until ‘SEtUP’ is shown, which

indicates that the scale is in Configuration parameter setup mode.

2. During setup mode, press the UNIT/HOLD key to change the flashed digits. Press the TARE key to confirm the

flashed digits. Press the ZERO/ON/OFF key to exit this mode.
