It is intended for application as a non-automatic weighing instrument only, i.e. the material to be weighed is manually and carefully placed in the center of the weighing pan.

  • Page 8: Monitoring The Metrological Parameters Of The Instrument

    2.4. Monitoring the metrological parameters of the instrument Metrological features of the balance should be tested by the user within regular intervals of time, within scope of quality assurance. 2.5. Data included in this user manual Please read the user manual carefully before erecting and commissioning, even if the user has is experienced with this kind of weighing instruments.

  • Page 9: Unpacking

    Please take special safety measures when weighing magnetic loads, as part of this balance is a strong magnet. If there is a necessity to perform measurement of such load, please use option of under hook weighing, which removes the load from area influenced by the magnet. For installation place of under hook device, please look at the bottom casing of the balance,.
