3 Basic instructions 3.1 Proper use The balance / counting system you purchased is intended to determine the weighing value of material to be weighed. It is intended to be used as a “nonautomatic balance”, 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 / counting system for dynamic weighing.
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 / counting systems 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 / counting system.
6.3 Installing / removing transport fittings Remove transport lock, if applicable. KERN CFS 3K0.5, CFS 6K0.1: KERN CFS 300-3: Bulk scales KERN KFP (illustration example): KERN KFP 6V20M, KFP 6V20LM, KFP 15V20M. Please take further details from the installation manual, added to the platform.
Install weighing plate and wind screen, if applicable, if needed. Level balance with foot screws until the air bubble of the water balance is in the prescribed circle. Check levelling regularly Interconnect reference scale and bulk scales via the second-scale interface in the counting systems KERN CCS. 6.4 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.
6.6 Connection of peripheral devices Before connecting or disconnecting of additional devices (printer, PC) to the data interface, always disconnect the balance from the power supply. With your balance, only use accessories and peripheral devices by KERN, as they are ideally tuned to your balance. 6.7 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).
7 Basic Operation 7.1 Switching on/off Actuate power switch (cf. chapter 2) at the right bottom of the scale to the front. The balance will carry out a self-test As soon as the weight display appears, the balance is ready for weighing. To switch-off push backward the switch-on/switch-out on the right lower side of the balance. 7.2 Zeroing Resetting to zero corrects the influence of light soiling on the weighing plate. The resetting range of the balance was adjusted to ± 2% max. by factory.
Display example model CFS 6K0.1: (1) Reference balance KERN CFS (2) Bulk scales, e.g.
7.4 Weighing with tare A tare value can be entered for the reference as well as for the bulk material balance. Before setting a tare value select active balance, see chap. 9.3. 7.4.1 Taring Deposit weighing vessel. After successful stop check press the TARE button. Zero display and the indicator [] above NET appear. The weight of the container is now internally saved. Weigh the material, the net weight will be indicated.
8 Parts counting Before the balance can count parts, it must know the average part weight (i.e. reference). Proceed by putting on a certain number of the parts to be counted. The balance determines the total weight and divides it by the number of parts, the socalled reference quantity. Counting is then carried out on the basis of the calculated average piece weight. As a rule: The higher the reference quantity the higher the counting exactness.
8.1 Determination of the average piece weight by weighing 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. Input the number of reference pieces via the number keys. Wait for stability display and confirm with or (model CFS 50K-3) within 5 sec. The scale shall detect the average piece weight and will then display the number of pieces. Display example model CFS 6K0.
Display example model CFS 50K-3: CFS/CCS-BA-e-1422 29
Count the items Tare if necessary, place weighing good and read off the number of items. Display example model CFS 6K0.1: Display example model CFS 50K-3: Interconnecting an optional printer, the display value will be output by pressing (menu adjustments F1 oFF ACC off; F2 Prt P mode Print Au OFF, cf. chapter 12.2).

8.2 Numeric input of the average piece weight Set reference Input known average piece weight, e.g. 10 g, with the numeric keys and confirm with or (models CFS 50K-3) within 5 sec. 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]. Display example model CFS 6K0.
Display example model CFS 50K-3: Count the items Tare if necessary, place weighing good and read off the number of items. Interconnecting an optional printer, the display value will be output by pressing , display and printout examples cf. chapter 10.1.
8.3 Automatic reference optimization If at the reference determination the placed weight or the placed piece number is too small, in the display of the average piece weight the triangle symbol will appear over [ ] or [ ]. To optimize the calculated average piece weight automatically, add further parts whose number is smaller than that of the first reference determination. After the reference optimization sounds a signal tone. For each reference optimization the average piece weight is newly calculated.
8.4 Counting with counting system (Illustration 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 platform. • Smallest parts (max < 3kg) are counted on the precise KERN CFS.
Display example model CFS 6K0.1: In order to avoid errors at the piece number determination, both balances must be adjusted with the same acceleration due to gravity (see chap. 14).
9 Fill-to-target function The balance allows weighing of goods to a certain target 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 ). Audio signal: The acoustic signal is dependent of the adjustment in the menu block „F1 oFFBEEP“.
