Analyzer
ANALYSIS GRAPH SCALE 2000ppm ▪ ANALYSIS GRAPH SCALE (2000ppm by default) determines
the scale of the y- axis “CO2 analyzer’s ppm - CO2 readings” on
the Analysis Graph Screen (see section 2.1.4 Analysis Graph
Screen for details). This function allows the system to display
CO2 data peaks in optimal resolution on the LCD screen.
▪ The ANALYSIS GRAPH SCALE is independent of the CO2
ANALYZER RANGE described below. Note that, in certain
circumstances, when the displayed CO2 peaks on screen
exceeds the scale of the graph, the CO2 analyzer keeps
measuring and integrating the CO2 readings to obtain the TOC
result, without losing any CO2 data.
BAUDRATE 9600 ▪ BAUDRATE (9600bps by default) specifies the data
communication signaling speed of CO
2
Analyzer with the RS232
communication interface.
CO2 ANALYZER RANGE 1000ppm
▪
CO2 ANALYZER RANGE defines the full scale range of the CO
2
analyzer installed in the BioTector.
CO2 ANALYZER CAL ▪
The CO2 ANALYZER CALIBRATION menu allows the user to
change CO
2
Analyzer range and the CO
2
analyzer zero and
span parameters when necessary. If required, please contact
manufacturer or distributor for details of the procedures.
