3 Basic instructions

3.1 Proper use

The balance you purchased is intended to determine the weighing value of material

to be weighed. It is intended to be used as a non-automatic balcance, i.e. thematerial to be weighed is manually and carefully placed in the centre of the weighingpan.. As soon as a stable weighing value is reached the weighing value can be read.

3.2 Improper Use

Do not use balance for dynamic weighings. In the event that small quantities areremoved or added to the material to be weighed, incorrect weighing results can bedisplayed due to the stability compensation. (Example: Slowly draining fluids from acontainer on the balance.)Do not leave permanent load on the weighing pan. This may damage the measuring

system.Impacts and overloading exceeding the stated maximum load (max) of the balance,minus a possibly existing tare load, must be strictly avoided. Balance may bedamage by this.Never operate balance in explosive environment. The serial version is not explosionprotected.The structure of the balance may not be modified. This may lead to incorrectweighing results, safety-related faults and destruction of the balance.The balance may only be used according to the described conditions. Other areas ofuse must be released by KERN in writing.

3.3 WarrantyWarranty claims shall be voided in case

1. Our conditions in the operation manual are ignored2. The appliance is used outside the described uses3. The appliance is modified or opened4. Mechanical damage or damage by media, liquids, natural wear and tear

The appliance is improperly set up or incorrectly electrically connected

The measuring system is overloaded

3.4 Monitoring of Test Resources

In the framework of quality assurance the measuring-related properties of thebalance and, if applicable, the testing weight, must be checked regularly. Theresponsible user must define a suitable interval as well as type and scope of this test.Information is available on KERNs home page (www.kern-sohn.com with regard tothe monitoring of balance test substances and the test weights required for this. InKERNs accredited DKD calibration laboratory test weights and balances may becalibrated (return to the national standard) fast and at moderate cost.

4 Basic Safety Precautions

4.1 Pay attention to the instructions in the Operation Manual

Carefully read this operation manual before setup andcommissioning, even if you are already familiar with KERNbalances.

4.2 Personnel training

The appliance may only be operated and maintained by trained personnel.

5 Transport and storage

5.1 Testing upon acceptance

When receiving the appliance, please check packaging immediately, and theappliance itself when unpacking for possible visible damage.

5.2 Packaging / return transport

Keep all parts of the original packaging for a possibly required return.

Only use original packaging for returning.

parts.

Reattach possibly supplied transport securing devices.

Secure all parts such as the glass wind screen, the weighingplatform, power unit etc. against shifting and damage.


17/82


6 Unpacking, Setup and Commissioning

6.1 Installation Site, Location of Use

The balances are designed in a way that reliable weighing results are achieved in

common conditions of use.You will work accurately and fast, if you select the right location for your balance.On the installation site observe the following:

Place the balance on a firm, level surface

Avoid extreme heat as well as temperature fluctuation caused by installing nextto a radiator or in the direct sunlight

Protect the balance against direct draughts due to open windows and doors

Avoid jarring during weighing

Protect the balance against high humidity, vapours and dust

Do not expose the device to extreme dampness for longer periods of time.Non-permitted condensation (condensation of air humidity on the appliance)may occur if a cold appliance is taken to a considerably warmer environment.In this case, acclimatize the disconnected appliance for ca. 2 hours at roomtemperature.

Avoid static charge of goods to be weighed and weighing container.

Major display deviations (incorrect weighing results) may be experienced shouldelectromagnetic fields (e.g. due to mobile phones or radio equipment), staticelectricity accumulations or instable power supply occur. Change location or removesource of interference.


18/82


6.2 Unpacking, Scope of delivery

Remove device and accessories carefully from packaging, remove packaging

material and place device at the planned work place. Verify that there has been no

damage and that all packing items are present.

Scope of delivery / serial accessories:

Balance, see chap. 2

Mains adapter

Protective cover

Operating instructions

Transport Securing

6.3 Placing

The right place is decisive for the accuracy of the weighing results of high-resolutionanalytical and precision balances (see chap. 6.1).

Remove transportation lock

On the left lower side of the balance replace the golden-coloured screw with thesilver-coloured one (see label).

20/82


Levelling balance

Level balance with foot screws until the air bubble of thewater balance is in the prescribed circle.

Check levelling regularly.

6.4 Connect and switch-on power supply

Before connecting the mains adapter check if the printed voltage value is the sameas the local supply voltage. Only use KERN original mains adapter. Using othermakes requires consent by KERN.

Supply power to balance via mains adapter.

The balance will carry out a self-test Then the balance is set into stand-bymode, OFF is displayed.

To switch on press the ON/OFF button. During the display CAL adjustmentis automatically carried out with the internal adjustment weight (see chap.7.2). As soon as the weight display appears, the balance is ready forweighing.

To switch off, press the ON/OFF button again. The balance returns into stand-by mode.

6.5 Connection of peripheral devices

Before connecting or disconnecting of additional devices (printer, PC) to the datainterface, always disconnect the balance from the power supply.With your balance, only use accessories and peripheral devices by KERN, as theyare ideally tuned to your balance.

6.6 Initial Commissioning

In order to obtain exact results with the electronic balances, your balance must havereached the operating temperature (see warming up time chap. 1).During this warming up time the balance must be connected to the power supply(mains, accumulator or battery).

The accuracy of the balance depends on the local acceleration of gravity.Strictly observe hints in chapter Adjustment.


21/82


7 AdjustmentAs the acceleration value due to gravity is not the same at every location on earth,each balance must be coordinated - in compliance with the underlying physicalweighing principle - to the existing acceleration due to gravity at its place of location

(only if the balance has not already been adjusted to the location in the factory). Thisadjustment process must be carried out for the first commissioning, after eachchange of location as well as in case of fluctuating environment temperature. Toreceive accurate measuring values it is also recommended to adjust the balanceperiodically in weighing operation.

Observe stable environmental conditions. A warming up time (see chapter 1)is required for stabilization.

Ensure that there are no objects on the weighing pan.

10.1 Parts counting

Before the balance can count parts, it must know the average part weight (i.e.reference). Proceed by putting on a certain number of the parts to be counted. Thebalance determines the total weight and divides it by the number of parts, the so-

called reference quantity. Counting is then carried out on the basis of the calculatedaverage piece weight.As a rule:The higher the reference quantity the higher the counting exactness.

10.1.1 Determine reference by weighing

In weighing mode press MENU button. The master menu will be displayed.

Use the navigation buttons ( to select the menu item Piece counting.

Acknowledge using PRINT button, the currently set reference quantity isdisplayed.

If necessary place a weighing container, confirm the set reference piece numberby pressing the PRINT button.

Place as many pieces to add-up as required by the set reference piece number.

Acknowledge using PRINT button and wait for stability display.

As soon as the weighing result is stable, the determined average piece weight willbe taken over as reference weight.

The currently placed weight W, the reference weight MPW and the piece numberPCS are displayed.

Remove reference weight. The balance is now in parts counting mode countingall units on the weighing pan.

10.1.2 Numeric entry of the reference weight

If the piece weight (reference) is known, it can be entered directly. As the balance inthis method needs not to calculate any reference, the balance after confirming thereference piece weight will be directly in parts counting mode.

In weighing mode press MENU button. The master menu will be displayed. Use the navigation buttons ( to select the menu item Piece counting.

Acknowledge using PRINT button, the currently set reference quantity isdisplayed.

Use the MENU button to select the Manual setting.

Confirm by pressing the PRINT button.

Use the navigation buttons (see chap. 2.2.1) to enter the known reference pieceweight in grams. To set a decimal point press the CAL button long time. Theinput is deleted by pressing the TARE button a longer time.


From here on the balance is in parts counting mode and counts all pieces which areplaced on the weighing pan (see chap.10.1.1 Carry our parts counting).

If the minimum parts weight is not reached, an error message will appear. Use theON/OFF button to return to the weighing mode and restart the procedure.




53/82


10.1.3 Automatic reference optimization

In order to improve the counting exactness, the reference can be optimised byadding more pieces. At every reference optimisation, the reference weight iscalculated anew. As the additional pieces increase the base for the calculation, the

reference also becomes more exact. Leave the piece number on the weighing pan after setting the reference weight

Duplicate the number of pieces on the weighing pan and wait until the acousticsignal sounds. The reference weight is calculated anew.

Either repeat the reference optimisation by adding more pieces (max. 255 pieces)or start the counting process.

The automatic reference optimisation is not active when the referenceweight is entered numerically.

10.2 Density determination (Hydrostatic weighing)

Density is the relationship of weight [g] : volume [cm3]. The weight is determined byweighing the sample in air. The volume results from the ascending force [g] of thesample dipped in a liquid. The density [g/cm3] of that liquid is known (principle of

Archimedes).The density is determined with help of the underfloor weighing device.We recommend to switch off the automatic adjustment in the setup menu,see chap. 9.12.

10.2.1 Density determination of solids

Prepare the balance as follows:

Switch off the balance

Remove the weighing pan and carefully turn over the weighing balance.

Suspend hook for underfloor weighing (optional)
