  • Page 9: Basic Information

    BASIC INFORMATION 2.1. Intended use The purchased balance serves to determine the weighing value of loads in laboratory environment. 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. Weighing result should be read only after stable reading has been obtained.
  • Page 10: Monitoring The Metrological Parameters Of The Instrument

    2.4. Monitoring the metrological parameters of the instrument Metrological characteristics of the balance requires periodical inspection carried out by its operator. Inspection frequency is conditioned by ambient conditions in which the balance is used, types of performed processes and accepted quality management system in an organization. 2.5.
