  • Page 21: Scope Of Delivery

    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.

  • Page 22: Adjustment

    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).
  • Page 23 How to carry out adjustment:  Confirm menu setting „noLin“ by Ensure that there are no objects on the weighing plate. Wait for stability display, then press The currently set adjustment weight will be displayed. (example) To change by using the navigation buttons (see chap. 2.2.1) select the desired setting, the active digit is flashing.

  • Page 24: Linearisation

    6.9 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 monitoring of test equipment, you can improve this by means of linearization.

  • Page 29: Weighing With Tolerance Range

    7.8 Weighing with tolerance range You can set an upper or lower limit when weighing with tolerance range and thus ensure that the weighed load remains exactly within the set limits. During tolerance tests such as dosing, portioning and sorting the unit will indicate exceeded or undershot limits by emitting an optical or acoustic signal.
