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

• 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.
4.6. Connecting peripheral equipment The balance must be unplugged from the mains before connecting or disconnecting any peripheral equipment (printer, PC computer). Use only peripheral equipment recommended by the manufacturer with your balance. These have been ideally coordinated to your balance. On connecting a peripheral device, plug the balance to mains.
