Switching on the indicating instrument first shows
the software version and date on the LCD, and
then switches to a 

Configuration Display

showing the gas being measured, the purge gas
required for the CO

2

 sensor, and the membrane

model number for this sensor. 

A configuration
screen appears
briefly, before
switching to a

C a l i b r a t i o n

 screen for several seconds before

finally switching to an 

O2 Measurement Display

.

This display then alternates every few seconds

with one of the CO

 or °Brix/%Diet measurement

displays (illustrated left).

Once the ProBrix Plus PC Program software is installed on your PC, it is recommended that no screen
savers are set and that the PC is not switched off unless absolutely necessary. 
The PC Program maintains a window for each active LINE, which are activated via the 

Start Line A/B

command in the 

Configuration menu

, or by the 

A/B buttons

 on the toolbar at the top left of the screen.

The 

Numerical Indicator Panel

shows information relating to the last
measurement, and is divided into
four, containing the CO

2

 data, the

Brix/Diet data, the O

2

 data and the

temperature information. For each of
these, the units of measurement, the
most recent measurement value and
a vertical bar graph are shown.
The background colors show: 
•

GREEN

 measurements are within 

High and Low limits
•

ORANGE

 measurements are 

outside High or Low limits, but inside 
High/High and Low/Low limits
•

RED

 measurements are outside 

High/High or Low/Low limits or an 
error has occurred

The 

Status Panel

 is displayed below the indicator panel and shows the status for CO

2

, Brix/Diet and O

2

indicating 

Standby

, 

Measure

 or 

Fault

.

The 

Graphic Panel

 contains four charts showing the measurements over a one-hour period. Any one-

hour period within the last 7½ hours can be viewed using the horizontal scroll bar. The lines on the graph
are color-coded as per the description at the top of the panel. Placing the mouse cursor over a data point
on the graph will cause the cursor to change to a hand symbol. Clicking the mouse when the hand
symbol is visible will cause a message box to appear giving the values of the measurements, including
the time they were taken.
The 

Buttons Panel

 at the bottom of the window contains eight additional options.
