  • Page 30: Balance Calibration

    11. BALANCE CALIBRATION 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).
  • Page 31 Cycle of automatic calibration proceeds as follows: - balance software detects necessity of calibration and signalizes it by marker of Celsius degree or by black marker - from this moment time of 5 minutes is counted in which weighings can be performed - when this time elapses display indicates CAL_30 message and starts count down 30..29..28 do 0 (indicated value is the counter)
