3 Fundamental information (general) It is essential to read through and observe the complete operating instructions before installing and commissioning. 3.1 Intended use The balance you have acquired serves to determine the weighing value of the 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.
4 4.1 Fundamental safety information Observe the information in the operating instructions 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 Staff training The device may only be operated and looked after by trained members of staff. 5 Transport and storage 5.
6 Unpacking, installation and commissioning 6.1 Place of installation, place of use The balance is constructed in such a way that reliable weighing results can be achieved under normal application conditions. By selecting the correct location for your balance, you will be able to work quickly and precisely.
6.4 Battery operation FKB To insert the batteries (6 x 1.5 V) remove the battery compartment cover. Remove it with the help of a coin. In the each battery tube insert three batteries in the same polarity sense. Screw down again the battery cover. To save the battery, the background illumination can be switched off (see chap. 7.3). Moreover the AUTO-OFF function can be activated (see chap. 7.2.10).
6.8 Adjusting (go to 7.2.6) Using a precision weight, the accuracy of the balance can be checked at any time and adjusted. Warning: With verified balances, this precision adjustment is not possible. Exception: model KBJ with internal adjustment weight. Adjustment procedure: Check that the surrounding conditions are stable. A short warm-up time of about 15 minutes is recommended for stabilisation. 6.8.
6.8.2 Adjustment of the balance KBJ with internal adjustment weight After expiring of the warm-up time (wait > 299s), the balance KBJ is automatically adjusted, whenever switched-on again. Additionally, at any time another adjustment can be released manually via the keyboard. In order to carry out an exact adjustment, the environmental influences (draught/ vibration) must be kept to an absolute minimum. The weighing pan must be placed without load. An adjustment weight is not necessary here.

Printing and deleting of the average value can be triggered by the PRINT key Simple deleting is possible by pressing the TARE key.

7.3 Display background illumination After having switched on your balance and the zero display, press the „MODE“ button to select the menu point „Backlight“. Acknowledge by pressing the „YES“ button in order to switch on the permanent background illumination. By pressing the „NO“ button, the background illumination is switched off.
7.5 RS 232 C Data output via interface RS 232 C RS 232 C Data output via interface RS 232 C General information As a condition for the data transfer between the balance and a peripheral device (for instance printer, PC ...) both devise have to be set on the same interface parameter (for instance baud rate, parity ...). There are 5 methods for the data output via RS 232 C Data output via PRINT-Key The printing process can be released by the PRINT-key.
7.5.1 Description of the data transfer Structure of each data transfer: Bit-Nr. N B*: .

Blank or weighing value with unit, depending on the load on the weighing plate. Unit Carriage Return Line Feed 7.5.2 Numerator The Numerator is found under the menu point “Printer” and can be activated and deactivated.
7.7 Underfloor weighing Objects which, because of their size or shape, cannot be put on the scale, can be weighed by means of underfloor weighing. Proceed as follows: • Switch off the balance. • Turn the balance over, without loading the balance plate. • Open the cover plate on the base of the balance. • Hang on the hook for underfloor weighing . • Place the balance over an opening. • Hang the item to be weighed on the hook and carry out weighing.
8 Maintenance, upkeep, disposal 8.1 Cleaning Please disconnect the device from the operating voltage before cleaning. Only use a cloth dampened with mild suds and not aggressive cleaning agents (solvents or similar). Please ensure that fluids are not able to get into the device and rub off using a clean, soft cloth. Loose sample residue/powder can be removed carefully using a brush or hand vacuum cleaner. Remove any spilt material to be weighed immediately. 8.
9 Troubleshooting The balance should be switched off for a short time following an interruption in the programme sequence and disconnected from the mains supply. It is then necessary to repeat the weighing process from the beginning. Help: Interruption Possible cause Weight display is not illuminated. • The balance is not switched on. • The mains supply connection has been interrupted (mains cable not plugged in/faulty). • Power supply interrupted. .
