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. SK-VET V1.0 2 SME300000067 EXCELL PRECISION CO., LTD. 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.
