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.
