2. BASIC INFORMATION 2.1. Intended use Precision balance APPC series is designed to determine the weighing value of loads in laboratory environment. It is intended for application as a nonautomatic 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 – stability pictogram is visible on balance’s display. 2.2.
2.4. Monitoring 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.
4. UNPACKING, ASSEMBLING AND STARTUP 4.1.
• • Remove the weighing pan from balance’s housing and remove the transport protections, as shown on above figure. After unpacking, unscrew bolt (1) locking balance’s adjustment mechanism. • Assembly the weighing pan. Pay attention to correct positioning of the weighing pan on balance’s mandrels – the weighing pan must not touch balance’s housing, and it should rest steadily.
• Level the balance by turning its adjustable feet. Then using a wrench (3) tighten up the nut (2) on the adjustable foot (1) to balance’s basis until refusal point. Setting Before plugging to mains, level the balance using adjustable feet. Turn the feet in a way that the air bubble of the level is located centrally. • Only then plug the balance to mains (power socket is located at the back of balance’s housing). 4.3. • • • • 4.4. Standard delivery components Balance. Weighing pan. Power adapter.
