3 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! 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.
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. Versions in other languages are non-binding translations. The only binding version is the original document in German. 4.2 Personnel training The appliance may only be operated and maintained by trained personnel. 5 Transport and storage 5.
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.
6.6 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.

7.2.4 Display background illumination Switch on the balance and the zero display, then call-up the balance menu as specified in chapter 1. Select menu item „Backlight“ using the button necessary for the respective model. Acknowledge by pressing the „YES“ button in order to switch on the background illumination permanently. By pressing the „NO“ button, the background illumination is switched off.
7.3 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.
7.4 Interface RS 232C Data output via interface RS 232C General Information The previous condition for the data transfer between balance and a peripherical device (e.g. printer, PC ...) is that the appliances are set to the same interface parameters (e.g. baud rate, parity ...). 7.4.1 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 PC should be disabled for this process.
7.5 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.
8 Service, maintenance, disposal 8.1 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. 8.
