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.

key in the weighing mode to choose the desired weighing unit and the
display will show the “kg” or “lb” symbol on the top right of the LCD display.
2. The unit status will be memorized when turning the machine off.
(2). Totalising
1. The scale allows the next totalising operation, even when the weight value does not return
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.
2. The scale can totalise positive or negative weight but not both at the same time. The
totalised weight store must be reset to zero before it is possible to select positive or
negative totalising mode.
