BEFORE USING THE SCALE
Thank you for purchasing an EXCELL Electronic Digital Scale. In order to use the
scale properly, please read this User Manual carefully before use. If you have a
problem concerning the scale, please contact your supplier.
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.
6. Do not mix different types of dry battery or mix used dry batteries with new dry batteries.
SAFTY INSTRUCTIONS
1. Please confirm that the electrodes “+”、“-” are on the right position.
2. To avoid the electric leakage, please do not place the battery in high temperature, or try
to disassemble it.
3. Please do not mix different type of dry cells。
4. Please do not use new and old dry cells at the same time.
5. Please do not leave the empty dry cells in the scale.

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.

the scale correctly.
⇒ A/D value is higher than +31250.
⇒ The weight of the object is over the maximum capacity + 9 divisions.
⇒ After calibration the displayed resolution is greater than the internal resolution.
⇒ The gravity value is outside the range 9.772 ~ 9.829.
⇒ Error setting.
⇒ The weight value is greater than the zero range, when re-zeroing the
scale.

Automatic Power-off Function
When the weight on weigh pan is less than 10d or remains steady for the set time, the scale
will automatically switch off.
v Automatic power-off is not functional when using an ac adaptor as the power source.
Therefore, auto power-off is active ONLY when using dry batteries as the power source.
Auto Backlight Function
When the weight is over 10d, the backlight is on. After the weight is stable for 10 seconds or
