3 Basic Information (General)

3.1 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.

3.2 Improper Use

• Our balances are non-automatic balances and not provided for use in dynamic weighing processes. However, the balances can also be used for dynamic weighing processes after verifying their individual operative range, and here especially the accuracy requirements of the application.
• Do not leave permanent load on the weighing plate. 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 damage by this.
• Never operate the 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.

3.3 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

3.4 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.

4 Basic Safety Precautions

4.1 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.

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 the appliance 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.
→ Prior to dispatch disconnect all cables and remove loose/mobile parts.
→ Reattach possibly supplied transport securing devices.
⇒ Secure all parts such as the wind screen, the weighing plate, power supply unit etc. against shifting and damage.

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 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.

- Do not operate in areas with hazard of explosive material or in potentially explosive atmospheres due to materials such as gasses, steams, mists or dusts.

- Keep away chemicals (such as liquids or gasses), which could attack and damage the balance inside or from outside.

- In the event of the occurrence of electromagnetic fields, static charges (e.g., when weighing / counting plastic parts) and unstable power supply, large display deviations (incorrect weighing results, as well as damage to the scale) are possible. Change location or remove source of interference.

6.2 Unpacking

Carefully remove the balance from the packaging, remove plastic cover and setup balance at the intended workstation.

6.2.1 Placing

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

6.2.2 Scope of delivery / serial accessories:

• Balance, see chap. 2
- Mains adapter
- Protective cover
- Operating instructions
- Tripod (only for H models)

6.3 Mains connection

Power is supplied via the external mains adapter. The stated voltage value must be the same as the local voltage.

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

Important:

Before starting your weighing balance, check the mains cable for damage.
➢ Ensure that the power unit does not come into contact with liquids.
➢ Ensure access to mains plug at all times.

6.4 Storage battery operation (optional)

The optionally supplied battery is charged with the supplied power supply. Before the first use, the battery should be charged by connecting it to the mains power supply for at least 14 hours.

- The appearance of the battery symbol is the display windows indicates that the battery is almost exhausted. Charge the battery with the help of the supplied power pack.

Fix the tripod using the two side screws of the tripod holder.

Switch on the balance and check if the tripod display works.

Should this not be the case, detach the tripod from the balance and check the connections.

6.6 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. During this warming up time the balance must be connected to the power supply (mains, accumulator).

The accuracy of the balance depends on the local acceleration of gravity.

Strictly observe hints in chapter Adjustment.

6.7 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.

• Carry out adjustment as near as possible to the balance's maximum weight (recommended adjustment weight see chap. 1). Weights of different nominal values or tolerance classes may be used for adjustment but are not optimal for technical measuring. The accuracy of the adjustment weight must correspond approximately to or, if possible, be better than, the readability [d] of the balance. Info about test weights can be found on the Internet at: http://www.kern-sohn.com
• Observe stable environmental conditions. A warm up time (see chapter 1) is required for stabilization.
• Ensure that there are no objects on the weighing plate.
• Avoid vibration and air flow.
• Always carry out adjustment with the standard weighing plate in place.
• The adjustment is locked in weighing scales with type approval certificate.

To disable the access lock, destroy the seal mark and actuate the adjustment switch. Position of the adjustment switch, see chap. 6.8.1.

- Attention:

After destruction of the seal the balance must be re-verified by an authorised agency and a new verification wire/seal mark fitted before it can be reused for applications subject to verification.

Procedure when adjusting:

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.

	The weight value of the adjustment weight on the weighing plate will be displayed.Now the process of adjustment has been finished successfully.

In case of an adjustment error or incorrect adjusting weight the display will show an error message; repeat adjustment process.

6.8 Verification

General:

According to EU directive 2014/31/EU balances must be officially verified if they are used as follows (legally controlled area):

• For commercial transactions if the price of goods is determined by weighing.
• For the production of medicines in pharmacies as well as for analyses in the medical and pharmaceutical laboratory.
• For official purposes
• For manufacturing final packages

In cases of doubt, please contact your local trade in standard.

Balances in the legally controlled area (-> verified balances) must keep the error limits in the verification validity period – normally they are the double of the verification error limits.

When this verification validity period expires, a re-verification must be carried out. Should be necessary an adjustment of the balance to keep the verification error limits to satisfy the reverification requirements, this is not deemed a warranty case.

Verification notes:

An EU type approval exists for balances described in their technical data as verifiable. If the balance is used where obligation to verify exists as described above, it must be verified and re-verified at regular intervals.

Re-verification of a balance is carried out according to the respective national regulations. The validity for verification of balances in Germany is e.g. 2 years.

The legal regulation of the country where the balance is used must be observed!

Verification of the balance is invalid without the seal.

The seal marks attached on balances with type approval point out that the balance may only be opened and serviced by trained and authorised specialist staff. If the seal mark is destroyed, verification looses its validity. Please observe all national laws and legal regulations. In Germany a reverification will be necessary.

6.9 Checking the balance verification settings

For the adjustment, the balance must be switched over to service mode.

In the service mode the parameters of the balance can be modified. If this happened accidentally, please contact KERN.

In calibrated scales the service mode is locked individually for each switch. To disable the access lock, destroy the seal and actuate the switch.

Attention:

After destruction of the seal the balance must be re-verified by an authorised agency and a new verification wire/seal mark fitted before it can be reused for applications subject to verification.
