7.OPERATING INSTRUCTION
7.1 PLACING THE SCALE
Place this scale on a hard and strong
enough surface where is free from RF
interference, vibration, fire, direct
sunlight and excessive moisture.
Page 10
For best weighing result, always place
this scale on a level surface. This scale
is equipped with a bubble level. If
required, adjust the adjustable feet
underneath the scale to obtain a level
condition.
7.2 POWER ON/OFF THE SCALE
7.2.1To turn scale on, press ON/ZERO.
7.2.2To turn scale off, press OFF.
7.3 BACKLIGHT MODE
7.3.1Turn backlight on
a. press SET during normal operation.
b. Backlight is turned on.
NOTE: The backlight function is monitored by
a power saving program. Backlight will
be automatically turned off after
weight displayed is unchanged for about
30 seconds. Backlight will
automatically be turned on again by
pressing any key or when a new weight
is detected.
7.3.2 Turn backlight off
When backlight is on, press SET to turn
backlight off.
7.4 TARE FUNCTION
7.4.1 To Tare Off the Weight of a Container
Place a container onto platter, then
press TARE to tare off the weight of it.
After the TARE is pressed, the tare sign
will appear.
7.4.2 To Clear the Weight of a Container from
Memory
Remove the container from the platter
then press TARE. The tare sign will go
off indicating no container weight is
resided in memory.
7.5 ZERO FUNCTION
If Zero Status Sign does not appear when
scale is unloaded, press ZERO to reset
weight displayed to zero. Refer to
general specification table for maximum
zero range.
7.6 PLACING LOAD
Always place a load onto the platter
gently. Sudden shock, excessive force
Page 11
or overloading the scale may cause
damage to the weight sensor inside.
It is a good practice to remove all load
from platter when not in used. This would
prolong the lifetime of weight sensor.
7.7 WEIGHING FUNCTION

Status Sign is on.
b. Press MODE until the required weight
unit appears.
c. Place subject matter on platter and the
weight of it is displayed.
For best weighing result, refer to
general specification table for
recommended minimum weight to be
applied.
7.8 COUNTING FUNCTION
7.8.1 Turn scale on. Press MODE until the PCS
sign appears. Make sure that the Zero
Status Sign is on.
7.8.2 Sampling
Sampling is the first step of counting
transaction. By means of sampling
process, the unit piece weight is
obtained. The unit piece weight forms
the foundation of quantity calculation.
a. If a container is used, place the
container onto the platter first then
press TARE to tare off the w eight of it.
b. Place a sample size with known quantity
onto the platter. The number of the
sample size must equal to one of the below
value:
5, 10, 20, 50, 100, 200, 500 or 1000pieces
c. Press HI/LO/SAMPLE until 5 PCS
appears.
d. Press TARE until corresponding sample
number appears.
e. Press SET to confirm. The unit piece
weight is obtained and scale is now ready
for counting transaction.
Hint: It is usually true that the more the
sample size, the more accurate the
subsequent counting result.
NOTE: For best counting result, refer to
general specification table for
recommended minimum piece weight.
NOTE: An error sign will appear if the unit
piece weight is less than the feather
unit weight. Refer to Appendix E for more
Page 12
information.
7.8.3 Counting Transact ion
Put more subject matter or remove part
of the subject matter, the new piece
value is shown on the display.
7.9 AUTO PIECE WEIGHT ENHANCEMENT FUNCTION
In order to obtain the best counting
result and to avoid sampling error, this
scale is equipped with Auto Unit Piece
Weight Enhancement function.
This function is resided in memory once
the unit piece is obtained by the
sampling method as described in 7.8.2.
NOTE: Auto Unit Piece Weight Enhancement
Function will be terminated if a zero
weight is detected during the
transaction process. It is strongly
piece weight is unknown or individual
piece weight is not standardized.
7.9.1 How Auto Piece Weight Enhancement
Function Works.
7.9.1.1After a unit piece weight is obtained
by method as described in 7.8.2 then
place more/remove some subject matter
onto the platter. The new quantity will
be shown on the display.
7.9.1.2The Auto Unit Piece Weight Enhancement
Function will update the unit piece
weight if both of the below requirements
are met:
a. The quantity added to platter is more
than 4 pieces of previous maximum counts
previously attained from the same
transaction.
b. The quantity added to platter is less
than 100% of previous maximum counts
previously attained from the same
transaction.
7.9.1.3If the above requirements are met, a
new unit piece weight will be displayed
on the Unit Weight window and confirmed
by an audio "beep".
7.10 WEIGHT CHECK FUNCTION
This scale is equipped with Weight Check
Function. An audio and video signal is
generated to reflect the weight check
result.
Page 13
7.10.1 Set Audio Alarm Output
If an audio alarm output is required,
enter function 30 and set appropriate
parameter. Refer to INTERNAL FUNCTIONS
for more information.

d. Utilize MODE , TARE and ON/ZERO to
achieve required upper weight limit.
e. Press SET to confirm.
7.10.2.2Set Lower Weight Limit
a. Press MODE until the desired weight
unit appears.
b. Press HI/LO/SAMPLE twice.
c. The LO indicator appears.
d. Utilize MODE , TARE and ON/ZERO to
achieve required lower weight limit.
e. Press SET to confirm.
NOTE: Change of function, (e.g. from
weighing mode to counting mode) or
turned scale off will not result in the
lost of weight limits set.
NOTE: Weight Check will not function if a
weight unit, other than the weight unit
used to set the limits, is employed.
7.10.3Weight Check Transaction
Place a subject matter onto the platter.
The Weight Check result is displayed on
the display.
a. The HI indicator will appear when weight
detected exceeds the upper weight limit
preset.
b. The GO indicator will appear when weight
detected falls within the upper and
lower weight limit.
c. The LO indicator will appear when
weight detected is below the lower
weight limit preset.
NOTE: The scale will not display or generate
and comparison result/alarm if weight
detected is less than 40 d. Refer to
Appendix E for minimum weight required.
7.11 PERCENTAGE CHECK FUNCTION
7.11.1 Sampling
Page 14
Sampling is the first step of Percentage
Check function. By means of sampling
process, the weight of subject matter
at 100% is determined. Follow the below
steps for sampling.
a. Press MODE until the % sing appears.
b. Make sure that the Zero Status sign is
on.
c. If a container is used, place the
container onto the platter first then

piece weight is less than the feather
percentage weight. Refer to Appendix E
for more information.
7.11.2 Percentage Checking Transaction
Add/reduce something to/from the
subject matter, the new relative
percentage value will appear on the
display.
