General information
The software structure consists of five operating modes and four menus, which will be described in
more detail in the following sections. Measured values are continually shown in the display and/or in
the menus. The displayed TOC value is calculated from the difference in the ultrapure water
measuring cell and TOC-measurement measuring cell values.
Should an error occur, the corresponding fault message is transmitted via the potential-free output and
is shown in clear text in the 4th line of the display. In the case of several errors occurring at one time,
they are alternately shown in the display.

Operating modes
Interval operating mode after switching on
Initially press the ON/OFF button. Then the display will show at first the system version, the system
serial number and the software version number to display for 3 seconds. The system then automatically
switches to the Interval operating mode (see
“Interval operation” on page 45 ), whereby the green
backlighting of the display is switched on and remains on until system control is switched off via the
ON/OFF-button. The “UV” text message is displayed when the UV-lamp is switched on. The “TC”
message is displayed when measured values are subject to temperature compensation. Further to these,
the measured values for ultrapure water (measuring cell LF1) and temperature are also displayed. The
displays of messages and measured values are independent of the operating mode.
The TOC value is not shown in Interval mode.
