BEFORE USING THE SCALE
To enable you to use this scale correctly, we suggest that you read this manual carefully.
INSTRUCTIONS FOR USE
1. Please keep scale in a cool and dry place. Do not store at high temperatures.
2. Do not allow any liquids to come into or contact with the scale. If it is happened, wipe the scale
dry with a cloth.
3. Avoid objects impacting with the scale. Do not drop loads onto the scale or subject the weigh
pan to any strong shock loads.
4. The load placed on the weigh pan must not exceed the maximum weighing capacity of the
scale.
5. 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.
PREPARING TO USE THE SCALE
1. For accurate weight readings locate the scale on a firm level surface free from vibrations.
2. Avoid operating the scale in direct sunlight or drafts of any kind.
3. Remove any weight that might be on the weigh pan before the scale is switched on and avoid
leaving weight on the pan for long periods of time.
4. Once the scale has been switched on, it will go through a LCD display test and then re-zero to
be ready for use.
5. The scale requires 15~20 minutes warming up the machine before operation to ensure best
accuracy.
6. Please note when
symbol appears on the screen, the dry batteries need to be replaced.
7. All goods weighed should be placed in the centre of the weigh pan for accurate weighing. The
overall dimensions of the goods being weighed should not exceed the dimension of the weigh
pan.
