Preparation before Operation
1. Avoid operating the scale in the locations where there is too much temperature changes
and air flow, for example, the place under sunlight or air condition.
2. Use the independent power socket to avoid the interrupt of other electronic product.
3. When turning on the scale, do not place any object on the platter.
4. When operating the scale, place the object on the center of the platter. For the accuracy
of weighing, do not place the object over the range of the platter.
5. When the low power indication ( ) lights up, the scale needs to be recharged.

(3). Accumulation Function
1. Weight Accumulation
Place the object on the platter, after the weight display is stable, press M+ key
to save the present weight value into memory. Meanwhile, the screen displays
“total count accumulation” and then “total weight accumulation”, and the
accumulation (M+) indication “6” will be flashing. After 3 seconds, the screen will
display the weight on platter, and the accumulation (M+) indication “6” lights up.
If the weight is unstable after pressing M+ key, the screen will display “ ”.
4 The scale can be continuous to accumulate the next weight without re-zeroing.
When the changes of weight on the platter is higher than ±10d, press M+
key, after being stable, it’s capable to save the weight into memory.
4 Accumulation count is up to 9999, but display digit is up to 6.
2. Accumulation Clearing
♦ Press RECALL and then CE to clear all the accumulation.
♦ Accumulation will be cleared automatically after turning off.
3. Accumulation Recall
While pressing RECALL key, the screen will display “total count accumulation”,
and then “total weight accumulation”. It will be back to the original mode after
accumulation (M+) light “6” flashing for 3 seconds. If no accumulation, it will be back
to the original mode after the screen displays “total count accumulation”.
(4). Zero Function
If zero drift happens during operating the scale, which means no objects on platter,
but the screen displays tiny weight value, press ZERO/→ to re-zero. Meanwhile,
the screen will display the zero (à0ß) indication.
(5). Net / Gross Switch
If it has tare or pre-tare at present, press G/N/↓ and the screen displays the gross
value. Meanwhile, all the keys are no function, and press G/N/↓ to return displaying
net weight value.

(6). Low Voltage Auto Power off Function
Œ When the voltage of batteries is lower than 5.6v±0.1 v, it turns off backlight and
the screen displays the battery symbol to intimate it needs to be recharged.
• When the voltage of batteries is lower than 5.4v±0.1 v, it would auto power off;
meanwhile, if turning on again, the screen would not be countdown and only
displays the battery symbol. It would auto power off after 5 seconds, and it
needs to recharge immediately.
Ž When the voltage of batteries is lower than 5.2v±0.1 v, it can’t be turned on and
please recharge immediately.
(7). Tare Function

Œ Place the container on platter. After being stable, press TARE/← key to
re-zero. The screen will display net weight (Net) indication.
• Place the object into the container, and the scale will display the net weight of it.
Ž “Tare value” clearing
Remove both the container and the object on the platter; the scale displays the
negative value of the container. Meanwhile, press TARE/← again to clear
“tare value,” and the net weight (Net) indication disappears.
• “Tare value” recall
Press RECALL and then TARE/← ⇒ The screen displays “tare value”.
4 Capable of continuously taring until the summation of tare and pre-tare value

2. Weight of Known Container ( PRETARE )
Œ Press PRETARE key, and the screen displays ï ð . . Use
BL/↑ , G/N/↓ , TARE/← , ZERO/→ , ENTER , ESC keys to input
the presetting value. The functions are described as below:
Input the weight of container. After finished, the screen displays the negative
value of the container, and the net weight (Net) and pre-tare (PT) indications light
up.
• Place both the object and container on platter, and the scale displays the net
weight of it.
Ž “Pre-tare value” clearing
Press RECALL , PRETARE and then CE ⇒ to clear “pre-tare” value.
