4. MEASURING PROCEDURE
Power management
* Set the " Power Slide Switch " ( 3-7, Fig. 1 ) to the
" ON " position.
* Push and release the " Power Button " ( 3-4, Fig. 1 )
will power on the scale and the LCD will be light.
Push and release the " Power Button " again

it should set the Power Slide Switch " ( 3-7, Fig. 1 )
to the " OFF " position.
1)Considering the environment satiability, before the
operation it should let the scale stay the measurement
environment at least 10 minutes.
2)a.If intend to measure the weight of small particle or
liquid, then it can use the small container as the
interface.
b.Before make the measurement, put the container ( or
bowel ) on the platform as the interface, power on the
scale, push the " Tare Button " ( 3-3, Fig. 1 ), the
display will show " Zero " weight, then put the
weighting material ( or liquid ) into the container,
LCD will show the weight value.
3)Press the " MODE Button " ( 3-5, Fig. 1 ) once, it can
select the weight unit from g ( Gram ) to oz ( ounce ).

4)Over load indication :
When the display show " EEEEE ", it means the
weight load is over indication.
Under this situation, please do not increase the
weight load, other it may harm the load cell and
without warranty.
5)TARE/Zero function
After finish the first load weight measurement, push
the " Tare Button " ( 3-3, Fig. 1 ) and release, the
display will show " Zero " weight value,
@ If the first load weight value is < 20 gram, after
push the " TARE Button " , LCD will show the
" " indicator.
@ If the first load weight value is 20 gram, after≧
push the " TARE Button " , LCD will show the "
TARE " indicator.
Then put the second load on the platform, the scale
" Display " ( 3-1, Fig. 1 ) will show the weight value of
second load exactly.

Gross Weight, Net Weight
After the display show " TARE " indicator ( If the first
load weight value is 20 gram ).≧
* Push and release the " N/G Button ( Net/Gross Weight
Button ) " ( 3-2, Fig. 1 ) will show the gross weight
value ( the first load weight value + second load
weight value ), the " TARE " indicator will be
disappeared.
* Push and release the " N/G Button " ( 3-2, Fig. 1 )
again, will return to show the net weight value ( the
second load weight value ), the " TARE " indicator
will show on LCD again.
6)Counting Scale
a.Press the " MODE Button " ( 3-5, Fig. 1 ) once
until the indicator show to the " PCS "
b.Press the " N/G Button " ( 3-2, Fig. 1 ) once
can select the counting sample no. ( S=10,
S=20, S=50, S=100 ).
c. After the counting sample no. be selected ( for example
S=20 ), then put the samples ( for example 20 PCs )
on the platform.
Press the " MODE Button " ( 3-5, Fig. 1 ) once, the
display will show " CAL " then return to counting no.,
now the scale is ready for the counting measurement.
5. BATTERY REPLACEMENT
If battery is weak, LCD display will show " " indicator.
This reminds user to replace new battery.

1)Open " Battery Cover " ( 3-9, Fig. 1 ) located at the
bottom of the scale.
2)According to the device instruction, place batteries
( 1.5V AA size battery x 6 PCs) into the battery
compartment & replace the battery cover.
6. DC 9V AC/DC ADAPTER OPERATION
1)The scale will also be operated by the household ACV
power source (110/220/240 ACV) with a DC 9V AC/DC
Adapter ( optional, capacity 300 mA min.).
2)Plug the jack from the Adapter into the " DC 9V
receptacle " ( 3-8, Fig. 1 ).
3)Now the scale is ready for ACV operation.
7. CALIBRATION PROCEDURES
1)Set the " Power Slide Switch " ( 3-7, Fig. 1 ) to the
" ON " position.
2)Let the scale not power ON ( LCD is not light ).
Press the " TARE Button " ( 3-3, Fig. 1 ) continuously
at least 3 seconds until the display show the
offset value ( for example -8326... ) then release
finger from the " TARE Button ".
3)Push the " TARE Button " ( 3-3, Fig. 1 ) once
a while, the display will show the calibration
value ( 500 g ).
4)Put the 500 gram standard weight on the platform,
push the " TARE Button " ( 3-3, Fig. 1 ) once a while,
the display will show " PASS " and finish the calibration
procedures.
