Saved Data
By pressing M+ key, number of weighing process followed by the total
weight will be displayed for three seconds.
Deleting saved data
By pressing M+ key, during the no of weighing displayed press
SMPL key to clear the memory
Automatic Accumulation
This function is used to automatically add weighing values to the
memory and to get a print out , if printer is connected.
Place the load on the platform
After stable indicator displayed, will be hear a beep sound.
Remove the load from the platform.
The weighing value will be stored into thememory and display will
be show ACC 1, followed by the weighing value.
Then display will be come to normal weighing.
The balance should be return to zero or a negative value before
another sample can be stored.
It can continue the process; It may take up to 99 entries or up to
the capacity of the display.
4. CALIBRATION
Normal Calibration

and indicator HI or LOW will be displayed.
Enter Hi limit or Low Limitvalue by pressing numeric keys.
Press ZERO keyto confirm, display will be change to normal
display.
Note: The load weight must be greater than 20 scale divisions for the
check weighing operations.
To disable the check weighing function, enter zero into both limits
3.5Accumulation
The scale can be set accumulation; this function is used to add the
weighing values to the memory. When a weight is place on the platform, it
can add automatically to the scale or by pressing M+ key. For settings see
the parameter p5 aCC
Manual Accumulation
Place load on the platform.
After stable indicator shown, press M+ key.
Display will be shown ACC 1 and total weight will be displayed
for two seconds. Weighing value will be saved into memory. If printer
is connected data will be print.
Remove the load from the platform.
The balance should be return to zero or a negative value before
another sample can be stored.
It can continue the process; It maytake up to 99 entries or up to
the capacity of the display "Weight".

3. OPERATION
Initial Start-up
Warm-up time of 15 minutes stabilizes the measured values after
switching on.
3.1 Basic Operation
2. Power ON/OFF
Power switch is located below 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 backward the key.
3. 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.
4. 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 theplatform. 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.
Enter a tare value using by numeric keys.
This method allows you to enter a value for the tare weight from the
keypad. This is useful if all containers are the same or if the container is
already full but the net weight is required and the weight of the container is
known.
Ensure displayis in zero.
Enter the known tare weight by using numerickeys.
Press TARE to enter, weight will be stored as tare weight and
displayed with minus sign and net indicator.
Place the container on the platform, net weight will be displayed.
The tare will be rounded up according to the readability of the balance. For
example, if a tare value of 103g is entered into the 60Kg scale with 5g
readability, then the display will be shown -105g.
3.2Percent Weighing
Percent weighing allows to a display weight in percent, in relation
to reference weight.
Unload scale and set zero.
Place the reference weighton the platform.
Press %key to enter percent weighing function.
Display will be show 100.. 00 %, set as per reference
weight.
Remove the reference weight, display will return to 0.00 %
Place a sample; display will be show thepercentage of the
sample as per reference weight.
To return to normal weighing mode, press %key.

3.3Parts Counting
As per reference weight, balance will calculate average piece weight.
So, it should know the average piece weight for a reference weight.
The higher quantity of the reference weight is better to get the exact higher
counting.
Unload scale and set zero.
Press SMPL key to enter the parts counting.
Place the numberof reference weight on the platform, then
enter the reference value bypressing numeric keys and
follow to confirm ZERO key.
Then can add more goods to check as the parts.
Press MODE key to show display unit weight (g/pcs) Press
the SMPL key to return normal weighing mode.
3.4 Check Weighing
It can set an upper or lower limit when weighing with the limits range.
During the limit controls dividing the unit will indicate whether a value
upper or lower limits with an alarm sound.
See details for setting beep sound in Parameter p 12 bp
Beep 0: No beep sound in the limits. Beep function turned off.
Beep 1: When the weight is between the limits. OK indicator will
be show and beeper will be sounded.
Beep 2: When the weight is out of the limits, the beeper
will be sounded and when weight is between the limits OK
indicator will be shown.
To set Hi limit and Low limit,
Press and hold the HI LIMIT or LOW LIMIT key, display will be
show the current Hi Limit or Low Limit . Left digit will be flashing
