DATA LOGGING TAB

Select the 

Data Logging

 tab to change the parameters 

for logging the data.  

By default, the software collects one data point every 
1.3 seconds and stores the last 5000 data points in 
memory for display. The display can show up to 108 
minutes of data for each sensor. 

Where 

1.  Put the file location and name into the 

Where

 box 

either manually or by using the 

Browse...

 button.

 

File name:

 The date and the file name extension 

*.csv are automatically added to the file name.

2. Set the number of data points to be stored in each 

log file. 

NOTE: The default is 10,000 points. The maximum is 
64,000 points.

When the data point limit entered is reached, the data 
log automatically rolls over to a new file with the 
same name originally specified and a new time stamp.

What (Data Set) 

1.  Select the ports from which to log data.

2. Select the data types to log:

  a.  Basic data: 

    • Concentration 

    • IoR@20 

    •  Fluid temperature

  b.  All data: 

    • Concentration 

    • IoR@20 

    •  Fluid temperature 

      – Sensor temperature*

      – Pixel position 

      – Index of refraction (IoR)

*Expert mode only.

Figure 20. Data logging tab.

When 

1.  Select how often data is stored in the data log file:

  •  Every data point 

  •  5 seconds

  •  10 seconds 

  •  30 seconds 

  • Minute 

  •  5 minutes

2. Check the 

Also Save Existing Data

 box to continue 

storing raw data when averaged data is being 
displayed.

3. Enter a time to stop logging data, in hours or 

fraction of an hour as a decimal value. 

  •   For continuous data logging, leave the value  

at “0.”

4. Press 

Start Now

 to begin logging. 

The program maintains a count of the logged points 
on the left side of the screen. This confirms that the 
data is being logged.
