Depending on the sensor and operation mode, the user may see slightly different options. The available user

options for all measurement modes are described in Table 2

Description

Measurement Control

Scan the bus for sensors connected to the ESCom board.

This

“Open” option allows the loading of previously recorded csv files into the

EVK software when having the same csv file column structure. In case raw

data are included it allows post-processing of previously recorded CSV files

with the latest algorithms. For this usage, it is not necessary to connect the

EVK hardware.

The “Export” can be used to export a data file that was loaded

and post-processed with the latest GUI algorithms.

Clicking the

“Start Measurement” button starts running a continuous

measurement and changes the button function to

”Stop Measurement.”

Clicking the button again stops the measurement. All data captured during the

measurement session is stored in a CSV formatted output file. The name of

the output file can be selected either with an auto-name format or customized

file name. The sensor results will be saved in a comma-separated file (CSV)

which is user-selected via the file and path selection dialog when the sensor is

started. This CSV file contains multiple sensor parameters (the sensor

tracking number, the production lot number, calibration parameters, etc.) In

addition, typically all raw sensor signals (for example, resistances) for each

measurement step and temperature are recorded.

Note: Additional information and parameters are usually used for debugging

and validation only and the focus needs to be on the relevant parameters,

such as the algorithm results.

A comment (for example

, “Start gas exposure”) can be added to the recorded

data. After clicking the

“Comment” button, a position in the graph must be

clicked to place the comment. Use the ESC key to escape this function.

In this section it is possible to:

▪ Activate cursor in the visualization plot

▪ Open a dialog for more settings such as default log parameters

▪ Switch to a Simple Mode to display results without any graphs

▪ Provide help for GUI controls (first click

“Help” then click the object you

want information about)

▪ Exit the software

Sensor Select

This widget is used to select sensors for configuration and to configure

whether they are shown in the GUI and logged in the graph. After a bus scan,

all sensors and interface boards detected on the computer are listed here.

Measurement data is collected for all sensors and logged in the output file. To

remove a sensor or sensor type from data acquisition, right-click on the

corresponding element and chose ‘remove’. A new bus scan is required to

add the sensors again.

In addition, the first of each sensor type is displayed in the graphs. The

checkbox in front of each sensor is used to enable or disable plot

visualization.

Note: Only one sensor of each type can be plotted.
