2 Basic Information (General) It is absolutely necessary that you read and understand the operating instructions prior to installation and commissioning and follow the instructions during the process! 2.1 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.
3 Basic Safety Precautions 3.1 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. 3.2 Personnel training The appliance may only be operated and maintained by trained personnel. 4 Transportation & Storage 4.
5 Unpacking, Setup and Commissioning 5.1 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.
5.6 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 during the initial start-up, after change in location and variation of surrounding temperature.
6 Operation 6.1 How to turn on/off balance To turn on touch the screen surface Turn off by touching the OFF surface command All fields with rounded corners are touch fields.

8.2 Data output RS 232 C Technical data: 8-bit ASCII Code 1 start bit, 8 data bits, 1 stop bit, no parity bit Baud rate selectable from 2400, 4800, 9600 Baud (factory setting) and 19200 Baud. Sub-D plug 9-channel required For operation with interface faultless operation is only ensured with the correct KERN – interface cable (max. 2m) Pin allocation of the balance output socket (front view) Sub-D jack 9-channel 5 1 9 6 Pin 2: Transmit data Pin 3: Receive data Pin 5: Signal ground 8.
8.3.1 There are 4 kinds of data output via RS 232C Data output using the PRINT key The printing process can be triggered by pressing the PRINT key. The settings AUTOPRINT and AUTOPRINT should be disabled for this process. AUTOPRINT (data output according to weight application) The setting AUTOPRINT is located on the PRINTER path where you can turn it on or off.
8.4 Printer The serial interface RS 232 facilitates the connection of a printer. The printout shows the weight in grams. In counting mode either the piece number or the weight details will be printed out. In percentage mode the percentage proportion or the weight details will be printed out. Printout will take place after pressing the PRINT key. It is possible to number each printout continuously with the help of the numerator.
9 Service, maintenance, disposal 9.1 Cleaning Before cleaning, please disconnect the appliance from the operating voltage. Please do not use aggressive cleaning agents (solvents or similar agents), but a cloth dampened with mild soap suds. Ensure that no liquid penetrates into the device and wipe with a dry soft cloth. Loose residue sample/powder can be removed carefully with a brush or manual vacuum cleaner. Spilled weighing goods must be removed immediately. 9.
10 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.
