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
recharged.

4. Tare Function
(1) Put the container on the platter. When the weight displayed is stable, press the
TARE
key. 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
TARE
key again, the negative value is cleared and the display returns to
zero. The “Net” indicator is off.
Tare continuously: When the container weight increases or decreases continuously, it

6. Simple Counting
6-1 Counting mode access
Press the
UNITS
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
NET
GROSS
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
UNITS
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 (
Unit weight too small (
4
): total sample weight is less than 20 divisions
): unit weight is less than 1/5 division.
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.
