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 weighing.
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.
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. 6.2 Unpacking/erection Carefully remove the balance from the packaging, remove plastic cover and setup balance at the intended workstation. The balance must be installed in a way that the weighing plate is exactly in horizontal position.
6.4 Operation using a (rechargeable) battery (optional) Lift-off the battery cover on the lower side of the balance. Connect 9 V compound battery. Replace the battery compartment cover. For battery operation the balance has an automatic switch-off function which can be activated or deactivated in the menu (chapter 9). In weighing mode keep the PRINT-key pressed until [Unit] appears. Press MODE key repeatedly until „AF“ appears. Use the SET key, to confirm.
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. 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. 6.
6.9 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 closing cover at the balance bottom. • Suspend hook for underfloor weighing carefully and completely. • Place weighing balance over an opening. • Attach load to hook and carry out weighing procedure.

8 Basic Operation Start-up ON OFF Press ON button. The balance will carry out a self-test The balance is ready for weighing when the weight display appears. 8888 Switching Off ON OFF Weighing 0.0 g Press OFF button, the display disappears 0.0 g Place goods to be weighed on balance Wait for standstill control, after the standstill control, the weighing unit appears right hand in the display (e.g. g or kg) Read weighing result.
Weigh the material, the net weight will be indicated. 47.2 g The taring process can be repeated any number of times, e.g. when adding several components for a mixture (adding). The limit is reached when the whole weighing range is exhausted. The weight of the weighing container will be displayed as a minus number after removing the weighing container. The tare weight is saved until it is deleted. Delete tare TA R E Unload the balance and press the TARE button, the zero display appears. 0.
Plus/minus weighings TA R E For example unit weight control, fabrication control etc. Put the nominal weight on the weighing plate and tare using the TARE button. Remove the nominal weight Put the test objects subsequently on the weighing plate, the respective deviation from the nominal weight is displayed with the respective sign to „+“ and „-“. According to the same procedure also packages with the same weight can be produced, referring to a nominal weight.
• Back to weighing mode by pressing the MODE button. • Error message „Er 1“ Piece below minimum weight of piece (See chpt. 1 “Technical specifications“): Press MODE key and restart reference determination. • Taring The tare vessels can also be used for piece counting. Before starting piece counting use the TARE button to tare out the container.
Percent determination MODE CAL Percentage calculation facilitates weight display in percent related to a reference weight equivalent to 100 %. In weighing mode press MODE key repeatedly, until [100 %] is displayed. Put a reference weight which corresponds to 100 %. Store by pressing the SET key. Remove reference weight. SET M Place goods to be weighed on balance. The weight of the sample is displayed in percentage in terms of the reference weight.

Dosing and The Auto-Zero function is used to tare small variations in weight automatically. Zero-tracking 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). When apportioning involves small variations of weight, it is advisable to switch off this function.

9.4 Interface parameters Data output is carried out via interface RS 232 C.

rE Cr: The remote control commands s/w/t are sent from the remote control unit to the balance as ASCII code. After the balance having received the s/w/t commands, it will send the following data. Take into account that the following remote control commands must be sent without a subsequent CR LF.
10.4 Output on bar code printer The data transfer mode has to be set on „BA Pr“ (chapter 9.4). As bar code printer the Zebra printer model LP2824 is provided. Take into account that the output format of the balance is fixedly defined and cannot be changed. The printer format is stored in the printer, i.e. in case of a failure the printer cannot be changed with a new one from factory, previously it is necessary that KERN installs the respective software.
12 Instant help In case of an error in the program process, briefly turn off the balance and disconnect from power supply. The weighing process must then be restarted from the beginning. Help: Fault Possible cause The displayed weight does not glow. • The balance is not switched on. • The mains supply connection has been interrupted (mains cable not plugged in/faulty). • Power supply interrupted. Batteries are inserted incorrectly or empty No batteries inserted.
