1 Introduction

Thank you for purchasing a KERN WTB scale. These scales are rugged, simple to operate, and can be used without connection to an external power supply. The scale has a menu system which allows it to be adapted to your needs.

Please read through these Operating Instructions carefully, and always follow them!

1.1 Safety and the environment

– Read through these Operating Instructions carefully, even if you already have ex-

perience of KERN scales. Only ever use your scale as described in the Operating Instructions. Be sure to follow the instructions for putting your new scale into operation.

– Do not use the scale in a explosive environment. – For connection to the power supply use only the AC adapter delivered with the scale.

Before you connect the scale to the power supply check that the voltage stated on the AC adapter is the same as the local power supply voltage. If it is not, do not connect the AC adapter under any circumstances but contact your dealer.

– Although your scale is very ruggedly constructed, it is nevertheless a precision

instrument. Impacts to the weighing pan, or placing excessively heavy loads on it, can damage the scale.

– Observe local and national environmental regulations when disposing of the scale.

The scale is fitted with a storage battery that contains heavy metals. Do not dispose of the battery as normal waste! Observe local regulations for disposal of environmentally harmful substances.

1.2 Selecting a location

Selecting a suitable location makes a decisive contribution to precise measurement results and lengthens the service life of the scale: – Choose a stable, vibration-free surface which is as horizontal as possible.

– Ensure there are no excessive fluctuations in temperature, and no direct sunlight.

– Make sure that the environmental conditions are met (Chapter 9.1).

– Avoid drafts (e.g. from fans or air conditioning).

– After any major change of geographical position, the scale should be newly adjusted

(calibrated) (Chapter 4.3).

2 Putting the scale into operation

2.1 Remove the transport arrestment

• Remove the 3 screws of the transport arrestment in the weighing-pan support and the 3 plastic inserts between the weighing-pan support and the scale housing.

• Place the weighing pan on the scale.

2.2 Leveling the scale

• Level the scale horizontally by turning the leveling screws. The air bubble of the level indicator must lie within the black inner circle.

2.3 Power supply

The scale is normally powered by the built-in storage battery. The AC adapter is only used for charging the storage battery. While the battery is being charged, the scale receives power from the power supply network, so you can still work with the scale even if the battery needs recharging. Battery charging also continues while the scale is switched off. The time required for recharging depends on how low the charge in the battery has become. However, to avoid overcharging the battery, do not leave the scale connected to the power supply with the AC adapter for more than 24 hours.

Battery operation (AC adapter not connected) Observe the red LED above the battery symbol Y:

LED is not lit: The battery is sufficiently charged. LED flashes: The charge of the battery is almost exhausted. Connect

the AC adapter as soon as possible to recharge the battery.

Charging the battery/operating from the power supply

The connecting socket for the AC adapter is located underneath the balance adjacent to the front-left leveling screw. Remove the rubber plug and connect the AC adapter to the scale and to the power supply. Observe the red LED above the battery symbol d: LED flashes: The scale is receiving power from the power supply network, the battery is being charged. LED is continuously lit: The battery is fully charged, the AC adapter can be disconnected again.

3 Daily operation

3.1 Switching the scale on and off

To switch the scale on: Check that there is nothing on the weighing pan.

Press the ON/OFF key until the display appears. After the scale has been switched on, it performs a self-test in which all the segments and then various items of information about the scale are briefly displayed. When the weight display appears, the scale is ready to weigh and is automatically set to zero (the LED above the a symbol is lit).

To switch the scale off: Press the ON/OFF key and hold it down until “OFF” appears in the display. The display then goes out, and the scale is switched off.

Energy-saving function and automatic switchoff

For battery operation the scale has an energy-saving function and an automatic switchoff function which can be both activated and deactivated in the menu (Chapter 4).

If the energy-saving function is activated (factory setting), when the scale is powered from the battery it automatically switches into “Standby” mode after two minutes if no weight change takes place and no key is pressed. The display is filled with decimal points instead of digits. As soon as a weight is placed on the pan or a key is pressed, the scale returns to normal weighing mode.

If the automatic switchoff function is activated (it is deactivated at the factory), the scale switches off automatically after 15 minutes in “Standby” mode.

3.2 Simple weighing

• Set the scale to zero with the a key. The LED above the a symbol lights as confirmation.

• Place the item to be weighed on the pan. The LED above the a

symbol goes off.

• Read off the weighing result. The LED to the right of the weighing result shows the current weighing unit (the unit can be changed in the menu, see Chapter 4).

3.3 Weighing with tare

• Place the empty weighing container or packaging component on the weighing pan and press the TARE key to tare the scale. The zero display appears and the LED above the NET (net weight) symbol is lit.

• Place the item to be weighed on the scale and read the result (net weight of the item being weighed).

The saved tare weight is retained until you either define a new tare, or press the TARE key when the weighing pan is empty, or switch off the scale.

Defining limit values

• Press the F key. The current upper limit value is displayed (the LED above the

+ symbol is lit). If you want to set an upper limit value,

continue with the next step. If you want to set a lower limit value,

press the ON/OFF key and the LED above the symbol will be lit. Every time the ON/OFF key is pressed, the scale changes between the upper and the lower limit value.

• The first digit of the selected limit value flashes and can now be

changed. If you do not want to change the first digit, press the F key and the second digit will start to flash. Each time the F key is pressed, the display moves to the next digit. After the last digit the display returns to the first digit.

• To change the selected (flashing) digit, press the TARE key repeatedly until the desired number is displayed. Then press the F key to move to the next digit and change this digit.

• To complete the input, press the a key. The scale stores the limit value and returns to weighing mode.

3.4 Weighing with limit values

You can define an upper and a lower limit value and thereby ensure that the amount of substance weighed is always exactly within the defined tolerances.

Note: Limit-value monitoring is switched off at the factory and must be activated in the menu if required (Chapter 4.2, menu item S3). You can also specify in the menu whether the balance should warn of violations of limit values.

Weighing with limit values

Weighing in Weighing Mode is made easier for you by the two LEDs above the UNDER and OVER symbols as well as a beep. The behavior of the two LEDS and the beep depend on the respective setting in the menu (Chapter 4.2, menu item S3). The table below shows how the two LEDs and the beep behave for various settings in menu item S3.

S3 = No load on balance Load < lower limit value Load between limit values Load > upper limit value

The menu can be used to change the settings of the scale and activate functions. The menu consists of two parts, the user menu and service mode (see overview in Chapter 4.2). The user menu contains frequently used settings and functions and is easy to call up. Service mode provides the same possibilities as the user menu as well as additional functions for the service technician. To call up service mode a tool is required.

4.1 Operating the menu

Calling up the user menu

With the scale switched off, press the a key and hold it down. Switch on the scale with the ON/OFF key.

“Setup” appears briefly in the display and then the first menu block of the user menu (“S1”) appears.

Calling up service mode

Remark: If the scale is verified, the offical seal has to be destroyed. Once this seal has been destroyed, the scale must be reverified by an accredited organization, and a new offical seal must be affixed before the instrument may be used as a verified scale again! With the scale switched on, remove the cover of the storage battery underneath the scale (6 screws). Remove the calibration plate (2 screws). To remove the calibration plate, the sticker has to be destroyed which covers one of the two screws.

Use a small flat-tip screwdriver to short-circuit the two contacts in the rectangular opening (see arrow). “Setup” appears briefly in the display and then the first menu block of service mode (“CTY”) appears.

Selecting the menu block

Press the ON/OFF key to confirm the setting in the current menu block and then select the next menu block.

Changing the setting

After you have selected the desired menu block, you can use the TARE key to switch between the available settings. The number of available settings differs according to the menu block.

The scale was adjusted at the factory. However, we still recommend adjusting the scale when it is put into operation for the first time, and thereafter at regular intervals, especially after a change of location.

Adjustment can only be done in service mode (see chap.4.1). Before doing the adjustment, the geo adjustment value must be checked for correctness in the “GEO” menu block (see table in Chapter 7).

• In service mode call up the “CAL” menu block. With the TARE key select “CAL YES” and then start the adjustment with the ON/OFF key.

• Select the desired weight unit for the adjustment and confirm with the ON/OFF key. The units available depend on the selected region (menu block “CTY”): for the setting “EU” (Europe) only “kg” is available while for the setting “GE” (USA) there is a choice between “kg” and “lb”.

• Select the maximum capacity of the scale (this is printed below the display, adjacent to the level indicator) and confirm it with the ON/OFF key. Note: The values in the display have a 1000x higher resolution, i.e. a displayed value of 6000 represents 6 kg or 6 l b (depending on the unit selected previously) and a displayed value of 15000 represents 15 kg or 15 lb.

• The scale prompts you to empty the weighing pan. Remove any loads on the pan and confirm this with the ON/OFF key. The scale then performs a zero setting during which a counter is displayed which counts backwards from 5 to 1.

• After the zero setting, your are prompted to place an adjustment

weight on the pan which corresponds to 2/3 of the selected capa- city (in this example 4 kg/lb, corresponding to 2/3 of the weigh-

ing capacity of 6kg/lb). Confirm that the weight has been placed on the pan with the ON/OFF key. While the weight is being measur- ed, a counter is again displayed which counts backwards from 5 to 1.

• The scale now prompts you to load the weighing pan with the adjustment weight which corresponds to the selected capacity (in this example 6kg/lb). Confirm that you have placed the weight on the pan by pressing the ON/OFF key. While the weight is being measured, a counter is again displayed which counts backwards from 5 to 1.

• The adjustment is complete. Press the ON/OFF key to save the result and quit service mode. If you do not want to save the result, press TARE and confirm the “Abort” message with the ON/OFF key.

7 Table of geo adjustment values

After a major change of geographical location, the geo adjustment value must be changed according to the following table, and the scale must then be readjusted accordingly (Chapters 4.2 and 4.3).

4.4 Monitoring the test substances

The metrology features of the balance and any possible available adjusting weight must be checked at regular intervals within the scope of quality assurance. For this purpose, the answerable user must define a suitable interval as well as the nature and scope of this check. Information is available on KERN’s home page (www.kern-sohn.com) with regard to the monitoring of balance test substances and the test weights required for this. Test weights and balances can be adjusted quickly and at a reasonable price in KERN’s accredited DKD calibration laboratory (return to national normal).

4.5 Verification

General:

According to the EU guideline 90/384/EEC balances must be verified officially if they are to be used as follows (legally regulated area): a) For commercial transactions if the price of goods is determined by weighing

b) For the production of medines in pharmacies as well as for analyses in the medical

and pharmaceutical laboratory

c) For official purposes

d) For the production of finished packages

In case of doubt, please contact your local office of weights and measures.

Verification information: (see chapter 9.3 Declaration of conformity)

An EU qualification approval is available for those balances marked as appropriate for verification in the technical data. In the event that the balance is applied in an area subject to verification as described above, it must be officially verified and re-verified at regular intervals.

Re-verification of a balance is carried out in compliance with the respective legal provisions of the states. The term of verification validity for balances in Germany, for example, is normally 2 years. The legal provisions of the country of use are to be observed.

5 Error messages

Display Cause and remedy E11, E16, E18 Internal error (RAM/ROM/EEPROM). Contact dealer. E48 Error in the scale configuration. Check all parameters in service mode. ERROR Software error. Restart the scale with the ON/OFF key. If the error still occurs,

replace the storage battery (Chapter 8).

------ The weight value is unstable or zero setting is not possible. Check the environ-

mental conditions (drafts, vibrations, etc.). If necessary, change the filter settings in the menu (menu block “S4”, see Chapter 4). Under certain conditions there could also be a difference of air pressure between the scale housing and the surroundings. Unscrew the rear leveling screws until the ventilation openings under them are free. If water drains out, contact you dealer.

nnnnnn Overload (load exceeds weighing capacity by more than 9 display steps). Re-

move the load and set the display to zero with the a key. Readjust (calibrate) the scale if necessary.

WWWWWW When zero was set there was a weight on the scale. When the load is removed

this error message appears. Ensure that there is no weight on the pan and then press the a key. If the error message occurs again, the scale must be adjusted (calibrated).

Note: If the setting “S11” = “Off” was selected in the menu (Chapter 4.2), when zero-setting is done with a weight on the balance and the weight is then removed, the negative weight value is displayed instead of this error message.

6 Cleaning the scale

• Disconnect the scale from the power supply before starting to clean!

• Use a soft cloth (no acids, alkalis, or strong solvents).

• Do not use abrasive cleaning agents: they can scratch the display.

• If badly soiled, remove the weighing pan and leveling screws, and clean them separately.

• Observe company-internal and industry-specific regulations regarding cleaning intervals and permitted cleaning agents.

Netherlands Belangrijke aanmerking voor geijkte weegschalen in EG-landen

In de fabriek geijkte weegschalen dragen dit kenteken op het emballage-etiket en een groene M-sticker op het ijklabel. Deze kunnen meteen in gebruik genomen worden.

Bij weegschalen die in twee stappen geijkt moeten worden en geen groene “M” op het

ijklabel hebben, staat dit kenteken op het emballage-etiket.

De tweede stap van de ijking moet door het ijkwezen uitgevoerd worden.

De eerste stap van de ijking werd in de fabriek doorgevoerd. Deze omvat alle inspecties conform

EN45501-8.2.2. Voor zover in overeenstemming met de nationale voorschriften in de individuele staten de geldigheidsduur van de ijking beperkt is, is de exploitant van een dergelijke weegschaal voor

een tijdige herijking zelf verantwoordelijk.

De eerste stap van de ijking werd in de fabriek uitgevoerd. Deze stap omvat alle tests overeenkomstig

EN45501-8.2.2. Bij weegschalen met een analoge weegbruggenaansluiting moet aanvullend de nauwkeurigheid overeenkomstig EN45501-3.5.3.3 getest worden. Deze controle is niet nodig als de

terminal het serienummer van de weegbrug heeft.
