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 balcance”, i.e. the material to be weighed is manually and carefully placed in the centre of the weighing pan.. 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 weighings.
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.
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.
6.3 Transport Securing Ensure that transport guard has been removed (only existing in 6 kg models) 1 To loosen the transport guard screw out transport screw [1] anticlockwise. For transportation carefully screw-in transport screw clockwise till to the stopper and then fix it using locknut.

6.6 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. 6.7 Rechargeable battery operation (optional) The rechargeable battery is charged via the delivered power cable. Before the first use, the rechargeable battery should be charged by connecting it to the mains power cable for at least 15 hours.
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.

8 Linearisation Linearity shows the greatest deviation of a weight display on the scale to the value of the respective test weight according to plus and minus over the entire weighing range. If linearity deviation is discovered during a testing instrument control, you can improve this by means of linearization. Carrying out linearization is restricted to specialist staff possessing well acquainted with the workings of weighing scales.

10.2 Automatic adding-up With this function the individual weighing values are automatically added into the summation memory when the balance is unloaded without pressing and edited, when an optional printer is connected. CFS 3K-5, CFS 6K0.1, CFS 15K0.2, CFS 30K0.5 models: Menu settings: „F1 off“ „ACC“ „ON“ and „F2 Prt“ „P mode“ „Print“ „Au ON“, (see chap. 13.2) When using as counting system there can be totalized on the reference as well as on the bulk material balance.
11 Counting During piece counting parts can either be counted into a container or out of a container. To count a greater number of parts the average weight per part has to be determined with a small quantity (reference quantity). The larger the reference quantity, the higher the counting exactness. High reference must be selected for small parts or parts with considerably different sizes. The average piece weight can only be determined by stable weighing values.
11.1 Determination of the average piece weight by weighing 11.1.1 CFS 3K-5, CFS 6K0.1, CFS 15K0.2, CFS 30K0.5 models: Set reference Reset balance to zero or tare the empty weighing container if necessary. Place on the weighing plate a known number (e.g. 10 items) of individual pieces as a reference. Wait for the stability display, than enter the number of individual items via the numeric keypad. Confirm within 5 sec by pressing . The balance determines the average piece weight.
11.1.2 CFS 50K-3 models: Set reference Reset balance to zero or tare the empty weighing container if necessary. Place on the weighing plate a known number (e.g. 10 items) of individual pieces as a reference. Wait for the stability display, than enter the number of individual items via the numeric keypad. Confirm within 5 sec by pressing . The balance determines the average piece weight. Count the items Tare if necessary, place weighing good and read off the number of items.
11.2 Numeric input of the average piece weight Set reference Input known average unit weight with numerical keys and confirm within 5 secs. with or (CFS 50K-3 models). If in the weight display as weighing unit [kg] is active, the average piece weight will be displayed in [g]. If as weighing unit [lb] is active, the average piece weight is also displayed in [lb]. Count the items Tare if necessary, place weighing good and read off the number of items.
11.4 Counting with counting system (Display example) Bulk material balance e.g. KERN KFP Reference balance KERN CFS Here pieces of huge quantities will be counted. Due to its high resolution it is useful for accurate determination of the average piece weight. Big parts (max > 3kg) are counted on the weighing bridge. Smallest parts (max < 3kg) are counted on the precise KERN CFS.
12 Weighing to a certain target weight /target quantity and tolerance control The balance allows weighing of goods to a certain target weight (net weight) or target piece number within defined tolerances. With this function one can also check if the weighing good is within a defined tolerance range. Tolerance control is possible in weighing or target mode. Reaching the target value is indicated by an acoustic (if activated in menu) and an optic signal (tolerance mark ). 12.
CFS 3K-5, CFS 6K0.1, CFS 15K0.2, CFS 30K0.5 models: Press , tolerance control is started. The symbol over appears. Place the weighing goods and with help of the tolerance mark check if the net weight of the weighed goods is under, within or over the specified tolerance.
