position, then the scale already install under the
horizontal position completely.

2) Set the "gm" or "oz" unit by slide the "Unit Switch"

The Display(3-3, Fig. 1) will show "8.8.8.8.8" for a few
seconds, then "0" will appear again.

4) Apply the load to the platform gently, display will show

the measuring weight values.

* Do not exceed the over load capacity of the scale.

* Over weighting, the display will show "EEEEE".

5) Tare function :

After weighting the first item, press "Tare Button" (3-2a,
Fig. 1), scale will reset to zero values automatically.
At the same time, the LCD display will show the "Tare"

function should be execute again.

*

The max. tare capacity is the full capacity(500g).
