Installation
 Place the scale on a table.
 Carefully place the pan to the four holes on the top cover.
 Adjust the water mark bubble level.
 Connect the adaptor pin to the adaptor jack.
Adaptor jack is located below the right side of the scale.
 Adaptor connects into your AC power socket.
Pluggable equipment must be installed near an easily accessible socket
outlet with a protective ground/earth contact.
 Turn on the power switch.
On / Off switch is located below the right side of the scale. Press switch
forward to turn on the scale. If you want to turn off, press the switch
backward.
 Display will show the scale capacity and will start self-checking.
 After self-checking, display will return to normal weighing mode.
 Then you can start your operation.
Note: Initial Start Up.
Warm-up time of 15 minutes stabilizes the measured values after switching on.
Level Adjusting
Place the scale on a table.
Check the water mark. If bubble is not centered, adjust the leveling feet until it
becomes centered. Check the level when you change the location.

Connect Adaptor and Charging
 To charge the battery, insert the adaptor pin to jack. Adaptor simply plugs
into the main power. The scale does not need to be turned on.
 The battery should be charged for 12 hours for full capacity.
 Left to the count display is an LED to indicate the status of battery charging.
When the scale is plugged into the mains power, the internal battery will
be recharged. If the LED is green, the battery is fully charged. If it is red,
the battery is running low on battery and if yellow, the battery is being
charged.
 Do not use any other type of power adaptor than the one supplied with the
scale.
 Verify that the AC power socket outlet is properly protected.
Note: Please charge the battery before using the scale for the first time.

5. OPERATION
Initial Start-Up
Warm-up time of 15 minutes stabilizes the measured values after switching on
1. Power ON/OFF
Power switch is located below the right side of the scale. Press the key
forward until to turn on. The display is switched on and the self test is
started. If you want to switch off press the key forward again.
2. Zero
Environmental conditions can lead to the balance exactly zero in spite
of the pan not taking any strain. However, you can set the display of
your balance to zero any time by pressing key and therefore
ensure that the weighing starts at zero.
3. Tare
The weight of any container can be tared by pressing tare button so that
with subsequent weighing the net weight of the object being weighed is
always displayed.
 Load weight on the pan.
 Press key. Zero is displayed, and tare is subtracted.
 Remove weight from the platform. Tared weight is displayed. It can set
only one tare value. It can display with a minus value.
 Press key. Zero is displayed, tare weight is cleared.
4. Weighing Units
In the zero point and stable indicator on, press key to select the
weighing units(kg/lb)
5. PARTS COUNTING
5.1. Setting Unit Weight
 For this function you need to know the average weight of the objects to
count. This value can be obtained by weighing a known number of pieces
so that the balance calculation.
 Scales can be used to calculate the unit weight or the manual input of unit
weight can be used. It can increase the precision of the unit weight at any
time during the process of counting by the count displayed and pressing

. Make sure that the amount shown is the amount on the scale before
pressing the button.
 The weighing may be amended on the basis of greater numbers of
samples improves the accuracy of counting large quantities.
5.2. Entering a Known Unit Weight.
If the unit weight is known can be entered from the keyboard.
 Place the goods on the platform
 Enter the unit weight by using numeric keys
and press and hold key
For e.g.: 50.00
 Unit weight display will show the entered value
and count display will show pcs of the goods.
 Press key to clear the unit price.
5.3. Parts Counting.
Weigh a sample to calculate the unit weight to determine the average weight of
items to count, put a known number of pieces on the scale and insert their
content. The scale will perform the total weight divided by the number of samples
and will display the unit weight.
 Zero the scale by pressing the zero if necessary. If using a container, put it on
the scale and the tare weight gain by following the steps above.
 Place a known amount of pieces on the scale.
 When the viewer "Weight" is stable enter the quantity
Of pieces using the numeric keys.
 and press the . The number of units is shown
by the viewer "Count"

and the average weight shown
is calculated from the viewer "Unit Weight".
 Adding pieces on the scale,
increase the weight and count.
5.4. Automatic Part Weight Updates
After entering into parts counting, the display shows number of parts
corresponding to previous reference weight. So that continuity will be maintained
with previous parts counting this was interrupted due to power failure.
