VIEWING THE NET WEIGHT/GROSS WEIGHT Press the key to toggle between the net weight and the gross weight and vice versa. The value displayed is signaled by the LED NET (lit: net weight).
  • Page 15 The reset command of the gross weight does not run if there is even one of the following conditions: • Unstable weight (with control of the stability of the weight enabled). In this case, the reset command takes effect only if the weight stabilizes within 3 seconds or if the control of the weight stability is disabled (parameter “MOTION “...
  • Page 16 PROGRAMMING THE WEIGHT SETPOINTS The set setpoint values are compared with the weight to drive its logic output. The comparison criterion is established in the process of set-up of the logic I / O (see relevant paragraph). To access the Setpoint setting, press the key and follow the instructions on the table below.

  • Page 25: Calibration

    CALIBRATION The calibration described herein should be performed with the use of sample masses and/or product pre-weighed on a weighing scale. Before proceeding with the calibration of the full scale, always perform the zero calibration. During the calibration phase, the display shows the weight intermittently with the inscription CaL. ATTENTION: If you turn off the instrument without exiting the set-up menu, the programming executed is not stored.

LINEARIZATION PROCESS When planning the sample weight, values greater than the full scale, or lower than the previous point, or when the weight is not stable, are not accepted. If the entered value is accepted, it is proposed the next step, otherwise still the same.
