The balance purchased by you is intended to define the weighing value of weighed goods. 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.

• Our balances are non-automatic balances, not provided for the 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 pan. This can damage the measuring mechanism.

• Impacts and overloading exceeding the stated maximum load (max) of the balance, minus a possibly existing tare load, must be strictly avoided. The balance could be damaged.

• 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 beyond 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

Within the scope of quality assurance the metrological properties of the balance and of an existing test weight must be checked at regular intervals. 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.16 TPES-B_TPEJ-B-BA-def-2319 English 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 staff. 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.

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 shield, weighing pan, power unit etc. against shifting and damage.TPES-B_TPEJ-B-BA-def-2319 17 English 7 Unpacking, Installation 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 e.g. 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 appliance to heavy moisture over a longer time period. 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 weighed goods and 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.18 TPES-B_TPEJ-B-BA-def-2319 English

7.2 Unpacking and check

Remove the appliance and the accessories from the package, set aside the packaging material and install the appliance on the working place. Check if all parts of the scope of delivery are present and free of damage. Scope of delivery: Content Models up to 620 g Models from 1200 g to 15 kg Models with 31 kg

3. Weighing plate support

already pre-installed

7.3 Assembling, Installation and Levelling

The correct implantation site is important for the accuracy of the weighing results of high-resolving precision balances (see chap. 7.1).

7.3.1 Implantation of the balance

1. Place the weighing plate support of the balance (in PES 31000-1M the

weighing plate support is pre-installed)

2. Fix the weighing plate support with the screw

3. Put the weighing plate on the weighing plate support

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

the prescribed circle

Check levelling regularly

5. Connect the mains adapter (Installation of the mains adapter: see chap.

1. Plug the long side parts from above onto the short side parts. Ensure that

the sides point upwards with their flat guidance.

7.4 Mains connection

Select the country-specific mains plug and insert it into the mains adapter.

Check, whether the voltage acceptance on the scales is set correctly. The balance may only be connected to the power supply, when the data on the balance (sticker) and the local mains voltage are identical. Only use KERN original mains adapters. Using other makes requires consent by KERN.

Important: ➢ Prior to start-up check the mains cable for damages. ➢ Ensure that the mains adapter does not come into contact with liquids. ➢ The mains plug must be accessible at any time.

1. Place the country-specific power plug at a slight angle in the recess of the

mains adapter so that the spring points in the direction of the locking arrow of the mains adapter.

2. Push the locking mechanism of the power plug downwards and press the

power plug into the recess of the mains adapter. Then release the lock (make sure that the power plug is engaged).

Side view of the power plug (simplified):

Connect the balance to the power supply

Switch-on the balance by pressing the [ON/OFF]- button

7.5 Initial Commissioning

In order to obtain exact weighing results with the electronic balances, your balance must have reached the operating temperature (see warm-up time chap.1). For this warm-up time the balance must be connected to the power supply (mains connection). The accuracy of the balance depends on the local acceleration of gravity. Strictly observe hints in chapter Adjustment.

7.6 Connection of peripheral appliances

Before connecting or disconnecting the auxiliary equipment (printer, PC) to the data interface, the balance must be disconnected from mains without fail! With your balance, only use accessories and peripheral devices by KERN, as they are ideally tuned to your balance.

Press and hold the [F]- key for about 2 seconds.

9.6 Underfloor weighing

Objects unsuitable for placing on the weighing scale due to size or shape may be weighed with the help of the flush-mounted platform. Proceed as follows: Switch off the balance Open the closing cover in the balance’s bottom. Place the balance over an opening. Screw-in the hook completely. Hook-on the material to be weighed and carry out weighing.

• Always make sure that all attached objects are stable enough to keep safely the desired weighing goods (danger of breaking).

• Never suspend loads that exceed the stated maximum load (max) (danger of breaking) Always ensure that there are no persons, animals or objects that might be damaged underneath the load.

NOTICE After completing the underfloor weighing the opening on the bottom of the balance must always be closed (dust protection).

Models from 1200 g to 15 kg The hook for the underfloor weighing is available as optional accessoryTPES-B_TPEJ-B-BA-def-2319 31 English 10 Piece counting The piece counting application allows you to count several pieces placed on the weighing plate. Before the balance is able to count pieces, it must know the average piece weight, the so-called reference. For this purpose a certain number of the pieces to count must be put on the plate. The balance determines the total weight and divides it by the number of pieces, the so-called reference quantity. Counting is then carried out on the basis of the calculated average piece weight. As a rule: The higher the reference quantity the higher the counting exactness.

Select weighing application <1. SEt 2> (selection see chap. 9.4)

Press and hold the [F] key for about 2 seconds.

Either you can determinate one tolerance value only (minimum value as lower limit) or a tolerance range (several limits).

• Weighing with tolerance range is available for the following applications: Weighing, percent weighing, piece counting

Weight values can be evaluated in two ways when weighing with a tolerance range:

• Evaluation of absolute values o The evaluation is based on the permissible maximum and / or minimum value specified.

• Evaluation with difference values o The evaluation is based on a specified reference value and the permissible difference values. Example: A sample may weigh a minimum of 900.0 g and a maximum of 1200.0 g. The table below shows which values must be specified for the respective differentiation methods. Distinguishing method Reference value Lower tolerance limit Upper tolerance limit Absolute values

The following steps are needed to use weighing in the tolerance range:

1. Select function (see chap. 13.1)

2. Set differentiation condition (see chap. 13.2)

3. Set differentiation range (see chap. 13.3)

4. Set the number of tolerance limits (see chapter 13.4)

5. Set differentiation method (see chap. 13.5)

6. Activate / deactivate acoustic signal (see chapter 13.6)

7. Set the display of the results presentation (see chap. )

13.1 Selection of weighing function with tolerance range

13.2 Set distinction condition

The distinction condition defines whether the evaluation of weight values is performed only if there are stable weight values or continuously (in case of fluctuating / non-stable weighing values). The continuous assessment of weight values enables you to follow in real time on the display during dynamic weighing processes (e.g. when filling a container) whether your sample is within the tolerance limits.

13.3 Setting the distinction range

The differentiation range determines the weight value from which the scale starts to evaluate this value. If the entire range is set, the balance starts at 0 g. If 5d is set, the evaluation for the weighing systems is carried out according to the following table: Model Minimum weight for assessment to 620 g 0,005 g from 2200 g to 6200 g 0,05 g from 15 kg to 31 kg 0,5 g

Take over the measurement incertainty from the adjustment or the adjustment test with external adjustment weight66 TPES-B_TPEJ-B-BA-def-2319 English 17 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 warm up time (see

chapter 1) is required for stabilization.

• Ensure that there are no objects on the weighing plate.

• Avoid vibration and air draught.

• Always carry out adjustment with the standard weighing plate in place.

• The adjustment record is printed if an optional printer is connected and the GLP function has been activated.

• 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 re- verification will be necessary.72 TPES-B_TPEJ-B-BA-def-2319 English 19 Interfaces The balance can communicate with external peripherals using the interface. Data can be sent to a printer, PC or control displays. In the same way, control commands and data inputs may occur via the connected devices (such as PC, keyboard, barcode reader).

19.1 RS-232C interface for data input and output

The balance is equipped as per standard with an RS232C interface to connect a peripheral device (e.g. printer or computer).
