Dolphin 9903 V 1.1 SME300000041 2 INSTRUCTION FOR USE Thank you for purchasing the 9903 Dolphin II weighing scale of Excell. To enable you to use this scale correctly, we suggest that you read the following instructions carefully. 1. Don’t bump the scale against other items nor load it with heavy weight exceeding its full capacity. 2. Keep it away from high temperature. 3. If the scale is not going to be used for a certain period of time, clean it and store it in a polythene bag. A desiccant may be included. 4. If the scale is not used for a long period of time, recharge it every 3 months so as to ensure a long life of the battery. Fully recharge it before using again. Take care not to keep the scale being charged for too long. 5. Commodities should be placed at the center of the platter when being weighed, and can’t exceed the dimension of the platter. PREPARING TO USE THE SCALE 1. Please locate the scale on a stable, level surface to ensure accurate weight readings. 2. Adjust the four leveling feet to make the balance horizontal. Make sure that the level bubble is in the center of the circle. 3. Keep the scale away from places with strong drafts or excessive temperature fluctuations (e.g. direct sunlight or the air louver of an air conditioner). 4. There should be no weight on the scale when the scale is switched on. 5. Once the scale is switched on, it will go through a LCD display test and then re-zero to be ready for use. 6. Please warm up the scale for 15~20 minutes before operation. 7. Please note when the symbol flashes on the screen, the battery needs to be recharged.

Dolphin 9903 V 1.1 SME300000041 7 CHAPTER 4 BASIC FUNCTION OPERATION 1. Switch On When the scale is off, press the key to switch on the scale 2. Re-Zero When there is no load on the platter, if the displayed weight is not zero and is within the zero range, press the key to re-zero the scale, and the indicator “à0ß” is on. 4 Zero range: OIML & NTEP: ±2% of full scale; Sri Lanka: ±4% of full scale 3. Unit Selection Press the key to choose the weight unit “kg”, “lb” or the counting unit “Pcs”. The unit indicator “kg”, “lb” or “Pcs” will be on. 4 When the scale is switched off, it will memorize the active unit in use, and when it is switched on again, the previous active unit will be shown on the display. UNITS ON ZERO ON ZERO

The weight of the container is thus deducted, and the “Net” indicator is on. (2) Put the object to be weighed into the container, and the display shows the net weight of the object. (3) Remove the container and the object together from the platter. The display will show the negative value of the container weight. (4) Press the key again, the negative value is cleared and the display returns to zero. The “Net” indicator is off. 4 Tare continuously: When the container weight increases or decreases continuously, it can all be deducted by pressing the key. 4 Tare value can be up to the full capacity of the scale. 5. Net/Gross Weight Conversion In the Tare mode, when the “Net” indicator is on, press the key once. The display will show the gross weight, the “Net” indicator is off, and the Gross indicator “6” is on. Press the key again, the display will show the net weight, the “Net” indicator is on, and the Gross indicator “6” is off. Thus by pressing the key, the net weight and the gross weight can be displayed alternately. 4 The key is functional only under Tare mode. 4 When the gross weight is displayed, no key but the key is functional.

Simple Counting 6-1 Counting mode access Press the key to select the “Pcs” unit, and the scale enters the simple counting mode. 6-2 Sampling This important procedure is to let the scale calculate the unit weight: (1) Press the key to select a sample size 10, 20, 50, 100 or 200. (2) Put enough samples onto the platter according to the selected number, and then press the key. The display shows “- - - - - -” first. When the scale becomes stable, the display shows the number of samples on the platter. (3) Remove the samples from the platter, and the scale is ready to count. 6-3 Counting Place the objects to be counted onto the platter, and the quantity shows on the display. 4 When any of the following indicator is on, the scale can still count, but inaccuracy may occur: Sample too small ( ): total sample weight is less than 20 divisions Unit weight too small ( ): unit weight is less than 1/5 division. 4 The scale will memorize the last sample size when switched off, and the same can be used when the scale enters the counting mode next time. 4 If the number of samples changes by 5 pieces from the last sample used, the scale will calculate the new unit weight automatically.
