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.

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.
