BEFORE USING THE SCALE

To enable you to use this scale correctly, we suggest that you read this manual carefully.

1. Do not use scale in areas with excessive water and don’t spray the scale or indicator with

water when cleaning. Remove all water from the scale and indicator with a clean dry cloth.

2. The load placed on the platform must not exceed the maximum weighing capacity of the

scale.

3. Keep the scale away from high temperatures and damp conditions.

4. If the scale is not going to be used for some time, please clean it and store it in a plastic bag

in dry conditions. A desiccant sachet may be included to prevent moisture build up.

5. If the scale is not going to be used for some time, the internal rechargeable battery should

be recharged every three months.

6. Before using the scale after a long period of storage, please ensure that the internal battery

is fully charged.

NOTE: Care should be taken not to leave the internal battery on charge

for too long, as this may decrease the life of battery.

PREPARING TO USE THE SCALE

1. Locate the scale on a firm level surface free from vibrations for accurate weight readings.

2. Adjust the four levelling feet to set the scale platform level using the spirit level bubble

located on the scale platform frame.

3. Avoid operating the scale in direct sunlight or drafts of any kind.

4. Remove any weight that might be on the scale platform before the scale is switched on.

5. Once the scale has been switched on, it will go through a LCD display test and then re-zero

to be ready for use.

6. The scale requires 15~20 minutes warm up before operation to ensure best accuracy.

7. Please note when the

be recharged.

symbol is shown on the display, the internal battery needs to

8. All goods weighed should be placed in the centre of the platform for accurate weighing.

The footprint of the goods being weighed should not overhang the edges of the platform.

back to zero. The

key is functional, when the weight value changes by more

than 10 d. The scale will store the totalised weight value after the weight is stable.

totalised weight store must be reset to zero before it is possible to select positive or

negative totalising mode.
