A touch-screen interface provides access to all analyzer functions. The user interface consists
of a home screen from which all user operations initiate. The home screen displays the
current status of the analyzer and analysis results based on the current run mode selection.
The software can display data in a number of user-selected formats, including TOC,
compensated and uncompensated conductivity, resistivity, and temperature in engineering
units, with data logging and graphing of the data.
You may connect a USB flash drive to the analyzer and download the contents of the data
buffer, audit trail, alarm log, and bottle analysis reports. You can interact with the analyzer
remotely, including downloading data records, by querying the analyzer through an RS-232
communications port. You can communicate with the analyzer using Modbus
®
protocol via
the Ethernet port. Printing may be done automatically or on demand through an RS-232 port
to a serial printer.
The PAT700 allows for compliance to 21 CFR Part 11 with password protection and an audit
trail of all user actions.

1.3 RFID technology
The Anatel PAT700 on-line TOC analyzer Onboard Automated Standards Introduction
System (OASIS™) employs Radio Frequency Identification (RFID) technology, a registered
radio frequency device. The RFID system in the PAT700 operates over a very short distance
to eliminate any interference with other wireless communications.
The term RFID describes a system that transmits data wirelessly using radio waves. An RFID
system is comprised of a “tag” and a “reader/writer”. In the PAT700 analyzer, the tag is
attached to the standards bottles used in calibrations (conductivity and TOC), validations,
system suitability tests, and excursion mode. The RFID tag consists of a microchip attached
to a radio antenna mounted on a substrate. The RFID tag is attached to the bottom of the
standards bottle. The microchip contains data about the standard contained in the bottle. The
PAT700 OASIS system contains four RFID reader/writers permanently mounted inside the
analyzer that align with the bottle RFID tags when the bottles are fully loaded in the analyzer.
