Section 2 Instrument Overview
Check the indicated mains voltage at the instruments type plate, it should be
the same as within your laboratory. If not, you are not allowed to use the
instrument or connect it to the local mains supply.
PT-Node is used to collect serial data from Pharma Test instruments and stores
on a SD card inside of PT-Node. The data can be accessed through an FTP server
via ethernet (TCP/IP) or via a HTTP server through a web interface. This way the
supported Pharma Test instruments can be connected to a network with minimal
effort.
