3 Basic Information (General)
3.1 Proper 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.
3.2 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 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.
3.3 Warranty
Warranty claims shall be voided in case
•
Our conditions in the operation manual are ignored
•
The appliance is used outside the described use
•
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
EOB/EOE_L/EOE_XL/EOS-BA-e-1633 13
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 Transportation & 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 glass wind screen, the weighing platform, power unit etc. against shifting and damage.
14 EOB/EOE_L/EOE_XL/EOS-BA-e-1633
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.
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.
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.
6.2 Unpacking and placing
Open package, take out the appliance and accessories. Verify that there has been no damage and that all packing items are present.
The balance must be installed in a way that the weighing plate is exactly in horizontal position.
Mount the display unit in a way that facilitates operation and where it is easy to see.

16 EOB/EOE_L/EOE_XL/EOS-BA-e-1633
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 Battery operation
On the rear side of the display unit remove the battery cover and connect 6 x 1.5V mignon cells. Reinsert the battery cover.
In order to save the battery, the balance switches automatically off after 3 minutes without weighing. Further shutdown times can be set in the Menu (Function
"A.OFF"), see Section 9.
If the batteries are exhausted, the battery symbol will appear (see chap. 2.1). Switchoff balance and replace batteries at once.
If the balance is not used for a longer time, take out the batteries and store them separately. Leaking battery liquid could damage the balance.
6.5 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.
EOB/EOE_L/EOE_XL/EOS-BA-e-1633 17
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.
Observe stable environmental conditions. A warming up time (see chapter 1) is required for stabilization.
In weighing mode press the UNIT key and keep it pressed until „ CAL “ followed by the weight value of the required adjustment weight in displayed. „ LOAd “ is displayed alternatively.
Example
Carefully place the required adjustment weight (see tab. 1 „Technical data“) in the centre of the weighing plate
Press TARE key, adjustment is started.
Wait until the stability display appears, after that the adjustment is finished. The balance will automatically return to Weighing mode upon successful completion of the adjustment and will display the weight of the adjustment weight.
Take away adjustment weight.
An error message will be displayed in the event of an adjustment error or incorrect adjustment weight. Remove the adjustment weight and repeat the adjustment process.
Keep the adjustment close to the balance. Daily control of the weighing exactness is recommended for quality-relevant applications.
