3 Basic Information (General)

3.1Proper 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 plate. As soon as a stable weighing value is reached the weighing value can be read.

3.2Improper Use

Do not use balance for dynamic weighings. In the event that small quantities are removed or added to the material to be weighed, incorrect weighing results can be displayed due to the “stability compensation“ in the balance. (Example: Slowly draining fluids from a container on the balance).

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 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.

3.3Warranty

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 and damage caused by media, liquids, natural wear and tear

•The appliance is improperly set up or incorrectly electrically connected

•The measuring system is overloaded

3.4Monitoring 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

4.1Pay 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.

4.2Personnel training

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

5 Transport and storage

5.1Testing upon acceptance

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

5.2Packaging

Keep all parts of the original packaging in case you need to return the appliance. Only use original packaging for returning.

Before sending, disconnect all connected cables and loose/movable parts.

Attach possibly existing transport safeguards. Secure all parts, e.g. weighing plate, power unit etc., to prevent slipping and damage.

6 Unpacking, Setup and Commissioning

6.1Installation 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.

Therefore, observe the following for the installation site:

•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. Nonpermitted 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 charging of the material to be weighed, weighing container and windshield.

Major display deviations (incorrect weighing results) may be experienced should electromagnetic fields (e.g. due to mobile phones or radio equipment), static electricity accumulations or instable power supply occur. Change location or remove source of interference.

6.2Unpacking

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

6.2.1 Setup

The balance must be installed in a way that the weighing plate is exactly in horizontal position.

6.2.2 Scope of delivery

Serial accessories:

•Balance

•Weighing plate

•2 x transport security

•Mains power supply

•Protective cover

•Operating Manual

6.2.3 Basic structure

•Place the balance on a horizontal and solid base.

•Remove the transport security on the 4-point support.

•Pull off the protection foil from the weighing plate if existing.

•Attach the weighing plate.

6.3Mains connection

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

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

KERN.

6.4Operation using a (rechargeable) battery (optional)

Lift-off the battery cover on the lower side of the balance. Connect 9 V compound battery.

Reinsert the battery cover.

For battery operation the balance has an automatic switch-off function which can be activated or deactivated in the menu (chapter 8.1). Proceed as follows:

Switch-on the balance using the key and wait for the „0“ display.

Press the key and keep it pressed until „UNIT“ appears on the display.

Press the key four times, in the display appears „AF“.

Confirm by pressing the key.

Use the key to choose between the two following settings:

1)	„AF	on“:	To save the battery, the balance switches off automatically
			3 minutes after having finished the weighing procedure.
2)	„AF	off“:	Switch-off function deactivated.

Use the key to confirm your selected setting.
