300S Digital Readout

Features:
The 300S can be configured for 2-, 3- or 4-axis display in the turning and milling modes. The 300S is fluent in numerous languages (DE, EN, FR, ES, PT, IT, NL, SV, FI, HU, PL, etc.). This applies to the user interface as well as the entire on-line help documentation. The easy-to-use display contains many new and advanced features, which, however, do not complicate daily operations.

Operation:
The 300S is equipped with a 5.7” LCD monitor that replaces the cathode-ray monitor of the VRO300. The “soft keys” are used for diverse functions, mainly for operation and parameterization. The monitor is the same one currently used in the 200S series. In addition, the 300S is capable of all the functions of a programmable counter, such as the creation, editing, storing and running of programs. Numerous programs with differing names can be saved in the program list.

Mechanical compatibility:
The 300S can be installed on all counter mounting bases as well as in the existing mounting frames.

Electrical connection:
All digital ACU-RITE scales with D9 connectors can be connected directly to the 300S.
