1. INTRODUCTION
The KW series of bench scale provides an accurate, fast and versatile series of
general purpose weighing scale with counting and check-weighing functions.
All the keypads are sealed, color coded membrane switches and the displays are
large easy to read liquid crystal type displays LCD). The LCD’s are supplied with a
backlight.
All units include automatic zero tracking, audible alarm for pre-set weights, automatic
tare, and an accumulation facility that allows the individual weights to be stored and
recalled as an accumulated total.
2. KEY DESCRIPTION
Zero or 0
Set the zero point for all subsequent weighing. The display shows zero.
A secondary function , of "Enter" key when setting parameters or other functions.
Tare or
Tares the scale. Stores the current weight in memory as a tare value, subtracts the
tare value from the weight and shows the results. This is the net weight. Entering a
value using the keypad will store that value as the tare value.
A secondary function , of incrementing the active digit when setting a value for
parameters or other functions.
Smpl or
Enter counting mode from weighing mode. Shift unit weight, counts and total weight
when counting mode. Move the active digit right when setting values for other
functions.
UNIT or U
Press this key to select the weight unit. Move the active digit left when setting values
for other functions.
Func or F
Used to select the function of the scale. If the scale is weighing it will select parts
counting. Of it is not in weighing mode it will return the user to weighing.
Secondary function C ) , is to act as a clear key when setting values for parameters
or other functions.
Print/M+ or
To print the results to a PC or printer using the optional RS-232 interface. It also
adds the value to the accumulation memory if the accumulation function is not
automatic.
Secondary function ESC) , is to return to normal operation when the scale is in a
parameter setting mode.
ON/ OFF or
Turn on or off the power.

3. DISPLAY

4. FUNCTIONS
4.1 Zeroing The Display
You can press the ZERO/ENTER key at any time to set the zero point from which all
other weighing and counting is measured, within 4% of power up zero. This will
usually only be necessary when the platform is empty. When the zero point is
obtained the display will show the indicator for zero.
The scale has an automatic rezeroing function to account for minor drifting or
accumulation of material on the platform. However you may need to press the
ZERO/ENTER key to rezero the scale if small amounts of weight are shown when the
platform is empty.
4.2 Taring
Zero the scale by pressing the ZERO/ENTER key if necessary. The zero indicator will
be on.
Place a container on the platform, a value for its weight will be displayed.
Press the TARE key to tare the scale. The weight that was displayed is stored as the
tare value and that value is subtracted from the display, leaving zero on the display.
The "TARE" indicator will be on. As product is added only the weight of the product
will be shown. The scale could be tared a second time if another type of product was
to be added to the first one. Again only the weight that is added after taring will be
displayed.
When the container is removed a negative value will be shown. If the scale was tared
just before removing the container this value is the gross weight of the container plus
all product that was removed. The zero indicator will also be on because the platform
is back to the same condition it was when the ZERO/ENTER key was last pressed.
4.3 Weighing a sample
To determine the weight of a sample first tare the empty container then place the
sample in the container. the display will show the weight and the units of weight
currently in use.
4.4 Parts Counting
When the scale is showing weight, pressing the SMPL key will start the parts
counting function.

Before beginning, tare the weight of any container that will be used, leaving the
empty container on the scale. Place the number of samples on the scale. The
number should match the options for parts counting, 10, 20, 50, 100 or 200 pieces.
Press the SMPL key to begin. The scale will show "SP 10" asking for a sample
size of 10 parts. Change the sample size by pressing the TARE/ key. the display
will cycle through the options: 10,20, 50, 100, 200 and back to 10.
Press the SMPL key when the number matches the number of parts used for the
sample. As more weight is added the display will show the number of parts pcs).
Press the FUNC key to return to normal weighing.
4.5 Check-Weighing
4.5.1 About check-weighing
Check-weighing is a procedure to cause an alarm to sound when the weight on the
scale meets or exceeds values stored in memory. The memory holds values for a
high limit and a low limit.
Check range:
set hi-limit and low-limit as different value, also hi-limit value is larger than low-limit.
Check key point:
set hi-limit and low-limit as same value.
Check mode 2:
When check range, the display will show OK and the beeper will sound when the
weight is between the limits.
When check key point, the display will show Ok and the beeper will sound when the
weight is under the limits.
Check mode 3:
When check range, the display will show OK and the beeper will sound when the
weight is out of the limits.
When check key point, the display will show Ok and the beeper will sound when the
weight is over the limits.
4.5.2 Set limits
Press F key, it will display “F0 H-L”, press ZERO key to enter, use TARE key to
select “SET HI” or “SET LO”, press ZERO key to enter, use SMPL key to move
active digit, use TARE key to change value, use F key to clear value. After you enter
the value, press ZERO key to sure, press Print/M+ key to escape.

4.5.3 Set check weighing mode
Press F key to enter setting mode, press TARE until display show “F4 OFF”, press
ZERO key to enter, press TARE key until display show “BEEP”, press ZERO key to
enter, press TARE key to select BP 2 check mode 2), BP3 check mode 3), BP1 not
sound), press ZERO key to sure, press Print/M+ key to escape.
4.5.4 NOTE
The weight must be greater than 20 scale divisions for the check-weighing to
operate.
To disable the Check-Weighing function enter zero into both limits by pressing the
FUNC key when the current limits are shown then pressing ZERO/ENTER to store
the zero values.
4.6 Accumulated Total
The scale can be set to accumulate manually by pressing the PRINT key. See the
PARAMETERS Section for details of selecting the method using function "F5 P RT".
The accumulation function is only available when weighing. It is disabled during
parts counting.
The weight displayed will be stored in memory when the PRINT key is pressed and
the weight is stable.
The display will show "ACC 1" and then the total in memory for 2 seconds before
returning to normal. If the optional RS-232 interface is installed the weight will be
output to a printer or PC this type machine has no print function).
Remove the weight, allowing the scale to return to zero and put a second weight on.
Press the PRINT key, the display will show "ACC 2" and then the new total.
Continue until all weights have been added.
To view the totals in memory press enter the PARAMETER SECTION and use
function "F1 TOL". See below.
4.7 Animal Scales
KW can set as an animal scale when external resolution less than 1/3000, about how
to set it, see the technical manual of KW.
Let the animal on the platform, after some second, if reading data change between
the range you have set, you can hear beep sound and reading data will be locked,
after you let the animal leave the platform and reading data return to zero, KW will do
automatic accumulation operation, if you have connect with mini printer, KW will print
automatically.
To clear accumulation memory, press Print key when scale in ZERO point, this
function only available in animal scale mode.

5. PARAMETERS
The scale has 6 parameters that can be set by the user plus a method of entering the
calibration section.
To set parameters press the FUNC key.
The display will show the first function, "F0 H-L".
Pressing the TARE/+ will cycle through the other functions.
Pressing ZERO/ENTER will allow you to set the function. It may be necessary to
either use TARE/+ or set a value using the SMPL/ key to move the active digit and
then using the TARE/ key to increment a digit, followed by the ZERO/ENTER key
to enter the value. Use the PRINT/ESC key to leave a parameter unchanged.
For example when the display shows “F0 H-L” press the ZERO/ENTER key to
begin.
The display will show “Set Lo”, press the ZERO/ENTER key to set the low limit, or
press the TARE/+ to skip to the next parameter, “Set Hi” for setting the high limit.
After pressing the ZERO/ENTER key to set a limit, use the SMPL keys to change
the flashing digit, then use the TARE/ key to increment the flashing digit. Continue
to the next digit and set it as needed.
When all digits have been set press the ZERO/ENTER key to store the value. The
display will go back to the parameter just set, i.e. “Set Lo”. Advance to another
parameter if needed or press the PRINT/ESC key to return to weighing.

7. BATTERYFUNCTIONS
The weighing indicator can be operated from the battery if desired. The battery life is
approximately 100 hours.
When the battery needs charging a symbol on the weight display will turn on. The
battery should be charged when the symbol is on. The scale will still operate for
about 10 hours after which it will automatically switch off to protect the battery.
To charge the battery simply plug into the mains power. The scale does not need to
be turned on.
The battery should be charged for 12 hours for full capacity.
Just under the quantity 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 charged.
If the LED is green the battery has a full charge. If it is Red the battery is nearly
discharged and yellow indicates the battery is being charged.
As the battery is used it may fail to hold a full charge. If the battery life becomes
unacceptable then contact your distributor.
