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 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 

0

ˉ 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.
