4 Basic Information (General)

4.1 Intended 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 balance”, i.e. the material to be weighed is manually and carefully placed in the centre of the weighing pan. As soon as a stable weighing value is reached the weighing value can be read.

4.2 Improper Use

Do not use balance for dynamic add-on weighing procedures, if small amounts of goods to be weighed are removed or added. The “stability compensation” installed in the balance may result in displaying an incorrect measuring value! (Example: Slowly draining fluids from a container 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 be damaged by this.

Never operate balance in explosive environment. The serial version is not explosion protected.

The structure of the balance may not be modified. This may lead to incorrect weighing results, safety-related faults and destruction of the balance.

The balance may only be used according to the described conditions. Other areas of use must be released by KERN in writing.

4.3 Warranty

Warranty claims shall be voided in case

• Our conditions in the operation manual are ignored
- The appliance is used outside the described uses
• The appliance is modified or opened
- 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

4.4 Monitoring of Test Resources

In the framework of quality assurance the measuring-related properties of the balance and, if applicable, the testing weight, must be checked regularly. The responsible user must define a suitable interval as well as type and scope of this test. 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. In KERN's accredited DKD calibration laboratory test weights and balances may be calibrated (return to the national standard) fast and at moderate cost.

5 Basic Safety Precautions

5.1 Pay attention to the instructions in the Operation Manual

Carefully read this operation manual before setup and commissioning, even if you are already familiar with KERN balances.

5.2 Personnel training

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

6 Transport and storage

6.1 Testing upon acceptance

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

6.2 Packaging / return transport

Keep all parts of the original packaging for a possibly required return.
→ Only use original packaging for returning.
Prior to dispatch disconnect all cables and remove loose/mobile parts.
⇒ Pack weighing plate + accessories and power supply unit separately.
→ Secure glass windshield against slipping (e.g. using an adhesive strip).

→ Secure all parts against shifting and damage as depicted.

7 Unpacking, Setup and Commissioning

7.1 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 next to 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 room temperature.
• Avoid static charge of goods to be weighed or weighing container.

If electro-magnetic fields or static charge occur, or if the power supply is unstable major deviations on the display (incorrect weighing results) are possible. In that case, the location must be changed.

7.2 Unpacking, checking and installation

Open packaging and remove all parts carefully.

Verify that there has been no damage and that all packing items are present.

Scope of delivery / serial accessories

• Balance
- Mains adapter
- Operating instructions

Prior to any installation and assembly works, the balance must be separated from the mains supply.

→ Install the balance at the intended workplace.
The right place is decisive for the accuracy of the weighing results of high-resolution analytic balances (see chap. 7.1).
→ Remove the transportation lock (only models ADJ)

→ Put the following parts upon in the right order

• Carrier of weighing plate
• Weighing pan

7.3 Levelling

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

Two concentric circles with a central shaded region and an X-shaped cross, no text or symbols present.

i Check levelling regularly.

7.4 Electric power supply

Select a country-specific mains plug.

Check, whether the voltage acceptance on the scales is set correctly. Do not connect the scales to the power grid unless the information on the instrument (sticker) matches the local mains voltage.

Only use KERN original mains adapter. Using other makes requires consent by KERN.

Important:

Prior to commissioning check the mains cable for damage.
Make sure that the mains adapter will not be in touch with liquids.
The mains plug must be accessible at any time.

Connect the mains adapter to the connecting socket on the backside of the balance and to the power mains.

The display unit lights up. As soon as the balance is supplied with energy, the indicator [+] is displayed.

[Non-Text]

The error message

indicates that the balance was disconnected from power supply without pressing the ON/OFF button. Remedy:

Press ON/OFF. The device will carry out a display test.

The balance is ready for weighing once the weight indication appears.

7.5 Initial Commissioning

In order to obtain exact results with the electronic balances, your balance must have reached 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.

7.6 Connection of peripheral devices

Before connecting or disconnecting of additional devices (printer, PC) to the data interface, always disconnect the balance from the power supply.

With your balance, only use accessories and peripheral devices by KERN, as they are ideally tuned to your balance.

8 Adjustment

As 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 physical weighing 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). This adjustment process must be carried out for the first commissioning, after each change of location as well as in case of fluctuating environment temperature. To receive accurate measuring values it is also recommended to adjust the balance periodically 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.

8.1 Models ADJ

Fault Possible cause

The displayed weight does not glow.

• The balance is not switched on.
• The mains supply connection has been interrupted (mains cable not plugged in/faulty).
  • Power supply interrupted.

The displayed weight is permanently changing

• Draught/air movement
• Table/floor vibrations
• Weighing pan has contact with other objects.
• Electromagnetic fields / static charging (choose a different location / switch off interfering device if possible)

The weighing result is obviously incorrect

• The display of the balance is not at zero
- Adjustment is no longer correct.
• The balance is on an uneven surface.
• Great fluctuations in temperature.
• Warm-up time was ignored.
- Electromagnetic fields / static charging (choose a different location / switch off interfering device if possible)
