INSTRUCTIONS FOR USE
1) Please keep the scale in a cooland dry place. Do not store at high temperatures.
2) Please keep the scale clean and free frominsect infestation.
3) Avoid objects impacting with the scale.
4) The load placed on the weigh pan must not exceed the maximumweighing 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) If the scale is not going to be used for some time, the internalrechargeable battery
should be recharged every three months. (If using dry batteries, take the dry
batteries out before storing)
7) Remove the plastic drip cover fromthe scale for best accuracy.
PREPARING TO USE THE SCALE
1. Locate the scale on a firmlevelsurface free fromvibrations for accurate weight
readings.
2. Adjust the four levelling feet to set the scale pan levelusing the spirit levelbubble
located at the front of the scale.
3. Avoid operating the scale in direct sunlight or drafts of any kind.
4. If possible avoid connecting the scale to ac power outlet sockets which are adjacent
to other appliances to minimise the possibility of interference affecting the
performance of the scale.
5. 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.
6. Once the scale has been switched on, it will go through a LCD display test and then
re-zero to be ready for use.
7. The scale requires 15~20 minutes warmup before operation to ensure best
accuracy.
8. Please note when symbolappears on the screen, the internalbattery needs
to be recharged.
9. 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.

CHAPTER 2 OPERATION
2-1 SWITCH SCALE ON
To switch on the scale, ensure that the weigh pan is empty and press the ON/OFF
switch towards the (“|”) position and the scale will power on and set zero ready for
weighing or counting operations.
4If the scale has a RS232 option fitted, the interface card number will be displayed
during the power up sequence.
2-2 SWITCH SCALE OFF
To switch the scale off, press the ON/OFF switch towards the (“¡”) position.
2-3 DISPLAYBACKLIGHT
AUTO BACKLIGHT
Press Z key, the unit weight displays followed by pressing 5
When the weight is over 10 divisions or any key is pressed, the display backlight
will be switched on. When the weight returns to zero or the weight on platformis
less than 10 divisions, the display backlight will switch off after 5 seconds.
BACKLIGHTON
Press Z key, the unit weight displays followed by pressing 4
Backlight is on all the time.
BACKLIGHTOFF
Press Z key, the unit weight displays followed be pressing 6
Backlight is off.
4The backlight mode is stored in memory and will restored when the scale is
switched off and back on again.

2-4 SAMPLING SPEED & BACK TO ZERO SETTING
Sampling speed: 01 ~ 15 (01 = slow, 15 = Very fast)
The slower the sampling speed the more accurate the count will be.
The faster the sampling speed the less accurate the count may be.
Zero display mask:
The standard auto zero tracking facility will normally ensure that the
zero remains stable despite fluctuations in temperature or ac mains
voltage etc. However in exceptionalcircumstances particularly mist
conditions & other unstable environments a usefuladditionalfacility
is available.
With the zero display mask it is possible to configure the scale not to
showthe first division of the weight. When configured the weight
display will showzero as long as the weight is less than two display
divisions.
1= 1st division is displayed as zero
0= normalmode (1st division is displayed)

Value of full capacity of the scale
•Place weights on the scale equivalent to full load capacity. When the scale
is stable, it will calibrate automatically. While the scale is counting back to
zero, remove all the weights fromthe scale. The Calibration procedure is
finished.
4If full load is not available in weights it is possible to enter a weight value of less
than full load. Enter the weight value to be used and then place the weight on
the scale, when the reading is stable the scale will automatically calibrate.
While the scale is counting back to zero, remove all the weights fromthe scale.
The Calibration procedure is finished. The newcalibration will be stored and
recalled when the scale is switched off and on again.
Press CE key to exit fromthe calibration mode.
4Restore to the default setting: When the Auto calibration is miss-operated, and
the scale should be restoredto the default setting, please hold CE key and
press U.W. PST key, the default setting will be restored after the scale counting
back to zero.
2-6 ZERO FUNCTION
Press the Z key to re-zero the display with no load on the weigh pan. When the zero
is set correctly the 3”icon will be displayed adjacent to the (à0ß) symbolon the
weight display.
The zero setting range is ±2%of the capacity of the scale.

2-7 UNIT WEIGHT CALIBRATION
♦Two methods of unit weight calibration are available depending on the scale
configuration they are either:-
1. Auto Calibration ⇒if weight is over 10%of the last sampling value, the scale
will automatically re-calculate the unit weight.
Example:
Say the current unit weight is 2.5g. If the next batch of product of the same
type has a slightly different unit weight say 2.8g, then because the difference
between the to unit weights is greater than 10%the scale will average the two
values and set a newunit weight of 2.65g. If the difference in unit weights are
less than 10%then the unit weight is not re-calculated.
2. ManualCalibration ⇒Press SMPL key to determine the unit weight.
♦The Auto Unit Weight calibration is setting is a factory set option. If it is set to off
then the auto unit weight calculation is disabled.
