Turn on the power switch. On /
Off switch is locating below the right side of the scale. Press switch forward to
turn on the scale. If you want to turn off, press backward the switch.
Display will be show the scale capacity and will be starting self-checking.
After self-checking, display will be come 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 center adjust the leveling feet until reach
center. Check the level when you change the location.
Connect Adaptor
To charge the battery insert the adaptor pin to jack. Adaptor
simply plug into the mains power. The scale no needs to be
turned on.
The battery should be charged for 12 hours for full capacity.
Right side of the display there 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 has a full charge. If it is red,
the battery is nearly discharged 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.

4. 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. Switch on the scale
by pressing on/off. The display is switched on and the self-test is started. If you
want to switch off press again the key.
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 zero 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 tare 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 tare key. Zero is displayed, tare weight is cleared.

5. PARTS COUNTING
1. Setting Unit Weight
For this function you need to know the average weight of objects to count.
This value can be obtained by weighing a known number of pieces so that
the balance calculation, the average unit weight or manually entered
through the keyword.
Both scales can be used to calculate the unit weight or the manual input
that can be used to count on both scales. It can increase the precision of
the unit weight at any time during the process of counting by the count
displayed and pressing Smpl. 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.
2. Entering a Known Unit Weight.
If the unit weight is known can be entered from the keyboard.
Enter the value of unit weight using the numeric keys then press U.Wt.
While the display flashes. If nothing is done within seconds, the display
"UNIT WEIGHT" back to the previous value, otherwise it shows the new
value entered.
The sample is then stored in the balance and the net weight is
displayed together with the calculated amount based on the weight
per unit.
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 balance of the total weight divided by the number of samples and
displays the unit weight.
Zero the scale by pressing the zero if necessary. If you use 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
Smpl.
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.
If the scale is not stable, the calculation is completed.
If the weight is less than zero, the viewer "Count" shows a negative count.
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.

5. Setting High / Low limits.
Pressing Pst the user can select count or weigh and set limits. For example: Press
Pst will display "Hi Cnt" pass counting by weighing Press Tare “Hi cnt” “1.999”
appears at the upper limit current count, press the CE to cancel and change if
necessary. Press Tare “Lo cnt” “0.999” appears lower limit of the current count, press
the CE to cancel and change if necessary. Back to Press Tare weighing limits. i.e.,
possible to delete one or both of the limits. The cancellation of both the limits also
disables the function. If weight control is selected on the first display shows “Hi n e t”
and “Lo Ne t” .
5.1 Checking Alarm
Press and hold CE will display “Check net” (for weight checking), “Check PCS” ( f o r
Count C hecking) and “Check off”(for not use) .
6. Accumulation
The values ( weight and counting) displayed may be added to the values
aggregated by pressing the M +. The "weight" display will show the total
weight, the display "Count" will show the total counts aggregated and the
display "Unit Weight" shows the number of times Articles are saved in
memory. These values will appear for 2 seconds.
The balance must return to zero or a negative value before another sample
can be stored.
Other products may be added by pressing the M + key. It may take up to 99
entries or up to the capacity of the display "Weight".
To view the total value stored, press the MR when the balance is zero. The
total will be displayed for 2 seconds,
To free memory, press MR to call the stored value then press the CE to clear
all values.
7. Automatic Accumulated Totals
After entering into accumulation (by pressing M+), it will store values into memory.
The “weight” display will shows total weight and number of a cc umu l a tio n .
8. Auto Off
The scale can set Automatic power off. The function makes power down
when a scale is not operated by user to save battery power. It can set
different time options. For settings see the parameter.
9. Display-Back light
The scale has the option of back light. It can help to see white background and more
bright.
