As when using this method the scale need not determine the reference value, after the reference unit weight is confirmed the scale will be switched directly to the piece counting mode.

  • Page 63: Automatic Optimization Of The Reference Value

    12.1.3 Automatic optimization of the reference value To improve the counting accuracy, the reference value can be optimized by adding new pieces. For every reference value optimization, the reference weight will be recalculated. As the additional pieces increase the calculation base, the reference value also becomes more accurate.

    17 Ionizing unit (factory option for KERN ALJ-A03) 17.1 General information The ionizing unit has blades supplied with high voltage. In their immediate vicinity, there are ions generated with a positive and negative charge as a result of corona discharge. The ions are attracted by the weighed material with static charge, neutralizing the interfering static charge.
  • Page 98 Protect from any damage resulting from any fall, vibrations or impacts, see the label to the left. Always use the original power supply. The printed voltage value must be consistent with the local mains voltage. Injury hazard, the ion source blades are very sharp. The ionizing unit generates toxic ozone, ensure appropriate ventilation.

  • Page 101: Intended Use

    17.6 Intended use The ionizing unit should be used solely with electronic scales! • Discharging solid bodies or scale containers. Improved ionization results are obtained when the blower is on, the sample discharging time is reduced. • Discharging powdery samples. Discharging prevents swirls which are a problem for toxic samples.
