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.

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.

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 overloaded11 CPB-N / CPB-DM-BA-def-2432 English

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. Versions in other languages are non-binding translations. The only binding version is the original document in German.

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.

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 glass wind screen, the weighing platform, power unit etc. against shifting and damage.CPB-N / CPB-DM-BA-def-2432 12 English 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.

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

Level balance with foot screws until the air bubble of the water balance is in the prescribed circle.13 CPB-N / CPB-DM-BA-def-2432 English

Ensure that transport guard has been removed (only existing in 6 kg models)

To loosen the transport guard screw out transport screw [1] anticlockwise. For transportation carefully screw-in transport screw clockwise till to the stopper and then fix it using locknut.

6.2.2 Scope of delivery

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

6.4 Rechargeable battery operation (optional)

The internal battery is charged with the supplied mains cable. Before the first use, the rechargeable battery should be charged by connecting it to the mains power cable for at least 12 hours. The operating time of the battery is about. 70h. Charging time until complete recharging ca. 12h. AUTO-OFF function can be selected after 3, 5, 15, 30 min. to save the rechargeable battery (see chap.12). If an arrow appears on the weight display above the battery symbol or "bat lo" when turning on the balance, this is an indication that the capacity of the rechargeable battery will soon be exhausted. The balance will be ready to operate for about another 10 hours, then it will switch off automatically. Connect the power cable as soon as possible to load the rechargeable battery. The LED display under the piece number window informs you during charging about the charging status of the rechargeable battery. red: Battery is almost discharged green: Battery is completely discharged

6.5 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.

6.6 Initial Commissioning

A warming up time of 2 hours after switching on stabilizes the measuring values. The accuracy of the balance depends on the local acceleration of gravity. Strictly observe hints in chapter Adjustment.15 CPB-N / CPB-DM-BA-def-2432 English

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. 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 plate. Provide calibration weight, for details, see chapter 1 "Technical Data. "

After successful adjustment the balance automatically returns to weighing mode. In case of an adjustment error or incorrect adjusting weight the display will show an error message; repeat adjustment process.

6.8 Linearization (non-verified models only)

Linearity shows the greatest deviation of a weight display on the scale to the value of the respective test weight according to plus and minus over the entire weighing range. If linearity deviation is discovered during a testing instrument control, you can improve this by means of linearization.

• Carrying out linearization is restricted to specialist staff possessing well acquainted with the workings of weighing scales.

• The test weights to be used must be adapted to the weighing scale’s specifications; see chapter 3.4 “testing instruments control”.

• Observe stable environmental conditions. Stabilisation requires a certain warm-up time.

• After successful linearization you will have to carry out calibration; see

chapter 3.4 “Testing instruments control”

General introduction: According to EU directive 2009/23/EG balances must be verified if they are used as follows (legally controlled area): a) For commercial transactions if the price of goods is determined by weighing. b) For the production of medicines in pharmacies as well as for analyses in the medical and pharmaceutical laboratory. c) For official purpose. d) For manufacturing final packages. In cases of doubt, please contact your local trade in standard. After verification the balance is sealed at the indicated positions. Verification of the balance is invalid without the "seal".

Verification notes: An EU type approval exists for balances described in their technical data as verifiable. If a balance is used where obligation to verify exists as described above, it must verified and re-verified in 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! Balances with obligation to verify must be taken out of operation if:

• The weighing result of the balance is outside the error limit. Therefore, in regular intervals load balance with known test weight (ca. 1/3 of the max. load) and compare with displayed value.

• The reverification deadline has been exceeded.23 CPB-N / CPB-DM-BA-def-2432 English
