Non verified weighing systems: Indicator [] next to symbol displays: 1 that the weight value is stable GROSS 2 that the displayed weighing value is a gross weight value 3 that the balance is set to unit counting mode PRETARE HOLD M+ 4 that a PRE-TARE value is stored 5 that the indicated weight value is held in the display, until it is deleted. 6 that data are stored in an accumulative memory 7 That the current selected unit of weight is „oz“.
3 Basic Information (General) 3.1 Proper use The display unit acquired by you is used in combination with a load cell and serves to determine the weighing value of material to be weighed. It is intended to be used as a “non-automatic weighing system”, i.e. the material to be weighed is manually and carefully placed in the centre of the weighing plate. As soon as a stable weighing value is reached the weighing value can be read. 3.2 Improper Use Do not use weighing system for dynamic weighing.
3.4 Monitoring of Test Resources In the framework of quality assurance the measuring-related properties of the display unit 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 display units’ test substances and the test weights required for this.
6 Unpacking and placing 6.1 Installation Site, Location of Use The display units are designed in a way that reliable weighing results are achieved in common conditions of use. Precise and fast work is achieved by selecting the right place for your display unit and your weighing plate.
6.4 Transport Securing Remove the transportation safety device at the four marked positions: Transport Securing 6.5 Placing Mount the display unit in a way that facilitates operation and where it is easy to see. In order to raise the display, the display device can be mounted on an optional stand. 6.6 Mains connection Power is supplied via the external power supply unit. Insert the mains plug into the wall socket. Once connected, the instrument performs a self check.
6.8 Adjustment As the acceleration value due to gravity is not the same at every location on earth, each display unit with connected weighing plate 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 weighing system has not already been adjusted to the location in the factory).

7 Basic Operation 7.1 Start-up Press on/ off key, the equipment completes a self check. As soon as the weight display appears, the instrument will be ready to weigh. 7.2 Switching Off Press the on/ off key approx. 3 seconds, the display will turn off. 7.3 Zeroing Resetting to zero corrects the influence of light soiling on the weighing plate. Manual To unload the weighing system Press the ZERO button, the zero display and the indicator will appear.
7.5 Switch-over weighing unit Press the UNIT-key The weight gauge changes between „kg“and "g". 7.6 Weighing with tare After taring no numeric input of a tare weight can follow. After the numeric input of a tare weight, the system can only be tared if „tare weight > PRE TARE value“ 7.6.1 Taring Deposit weighing vessel. Wait for stability display, then press the TARE button Zero display and indicator net appear. The weight of the container is now internally saved.
7.6.3 Numerical input of tare (PRE-TARE) The known dead weight of a weighing container can be tared off by entering its weight as pre-tare deduction in order to ensure the net weight of the goods to be weighed in subsequent weighings is always displayed. Press the TARE- key, the active position flashes. Enter the known tare weight, e.g. 2 kg and acknowledge with TARE button. Numerical input, see chap. 2.1.1. The entered weight will be stored as tare weight and displayed with negative sign.
8 Applications: 8.1 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. Determine the unit weight and count 1.
Switch between number of items and weight With the UNIT key you can switch between number of items and weight: By switching the scale off and then on again the scale starts in the unit counting mode. The current reference weight remains stored until the reference is set again or the power supply is interrupted. The counting function is not active, if the weight is under 20d or if below the minimum piece weight (< 0.2 D) is reached.
8.2 Totalization Required settings in the menu: 1. Function „rSi 04“: Setting „M_Plus“, see chapter 12.4 2. Function „rSi 03“, setting F_M 10 or F_M11 (sample print-out see following overview, see chapter 12.3. F_M 10 (M+ accumulating mode 1): F_M 11 (M+ accumulating mode 2): Total = sum of net weight of each weight reading Total = Sum of gross weight of each weight reading Printout example (KERN YKB-01N) Printout example (KERN YKB-01N) 1.

The number of weighings, followed by the total weight will be indicated. The indicator above M+ shows. Remove the weighed good. More weighed goods can only be added when the display ≤ zero.
Place goods to be weighed, e.g. 7 kg. Wait for stability then press the M+/PRINT, it calculates. The weight value is added to the accumulative memory and given out when connecting an optional printer. Number of weighings, followed by the total weight will be displayed for 2 sec. Then the current weight value appears, the indicator above M + appears. Add more weighed goods as described before. Please note that the weighing system must be unloaded between the individual weighing procedures.
Display and output sum „Total“: When the scale is unloaded (zero indicator) press the M+/PRINT key, the number of weight readings followed by the total weight are indicated for 2 seconds. Press M+/PRINT to print out this display. Delete accumulative memory: 1. With M+/PRINT : At the display “Number of weighings” press M+/PRINT key again. The data in the accumulative memory are deleted. The indicator above M+ turns off. 2.

10.10 Auto Zero This function is used to tare small variations in weight automatically. In the event that small quantities are removed or added to the material to be weighed, incorrect weighing results can be displayed due to the “stability compensation“. (e.g. slow flow of liquids from a container placed on the balance, evaporating processes). When apportioning involves small variations of weight, it is advisable to switch off this function.
11 External adjustment "Unverified weighing systems „ (menu block "02 EC”) • • Prepare the required adjustment weight. The weight to be used depends on the capacity of the scale. Carry out adjustment as near as possible to the scale’s maximum weight. Info about test weights can be found on the Internet at: http://www.kern-sohn.com. Observe stable environmental conditions. Stabilisation requires a certain warm-up time.
Ensure that there are no objects on the weighing pan. Press the TARE key. The weight value of the required adjustment weight will be displayed.
