In the SETTINGS tab, you can view and adjust various SensorControl settings, and clear alarms.

Figure 1: SETTINGS Screen

The settings are described in the sections below:

Measurement Settings

The settings in the Measurement settings area are:

  • Full spectrum — Full spectrum measures data points from the entire wavelength range of the sensor.

    Figure 2: Full Spectrum
    Full Spectrum
    • First WL (nm) — The first wavelength to be measured.

    • Last WL (nm) — The last wavelength to be measured.

    • Step WL (nm) — The step or separation of each consecutive spectral data point.


    In Full spectrum mode, the step calculation is started from the first wavelength value. For example, if the first WL is 1605, the last WL is 1800, and the step is 40 nm, the spectrum wavelengths will be 1605, 1645, 1685, 1725, and 1765.

  • Manual selection — In Manual selection, you can enter all the wavelengths that will be measured, manually into a list.

    Type the wavelengths (in nm) to the list, and press Return on the keyboard to add a new row. When done, press the UPDATE button, whereupon the program will check the entered values against the sensor’s wavelength range. The points outside of the sensor’s range will be discarded. It is possible, however, to measure a single spectral wavelength multiple times in a single measurement.

  • Points — This field indicates the number of points that will be measured.

  • Sensor's wavelength range — This field indicates the first and last wavelength to be measured.

  • Lamp mode — The lamp mode options are:

    • Manual — The lamp is on manual mode. This is the recommended mode for measuring, for example, moving samples, or when using the SMA connector and an external light source.

    • Auto lamp mode — The lamp is on automatic mode.

    • Auto lamp with dark substraction — The lamp is on automatic mode, but it measures the dark reference prior to each measurement. This is the recommended mode for measuring static samples with reflection optics and the integrated light source.

Port Settings

The settings in the Port settings area are:

  • Port selection mode — Select the port selection mode. The options are:

    • Automatic detection — The software automatically detects the sensor port.

    • User Selectable Port — If the automatic detection of the sensor does not work, select the port manually. If you select this option, select also the desired port from the COM-port drop down list.

Saving Settings

The settings in the Save settings area are:

  • Save path — The location on your computer for saving data.

    Click the folder icon to select the file saving location.

  • File name — The file naming convention for saving data.

    The file name will be automatically updated, when the Measurement settings are adjusted, by pressing the UPDATE button in the Measurement settings area. The default file name is the current date and time in format YYYY-MM-DD_hh-mm-ss.

  • Number of measurements — The number of spectra that will be saved in one cycle.

  • Interval — The time between each spectrum saving, in seconds. Each save cycle is started, when you press the SAVE button on the Measurement screen. If you set this value to 0, every single spectrum will be measured.

    For example, if the Number of measurements is 10, and the Interval is 6, a spectrum will be saved every 6 seconds, and the total save cycle time will be 60 seconds.

  • Save following data — With these options, you can save both the raw data and absorbance data values at the same time, as well as the results of the active analysis method. All three datasets will be saved into separate files. The different saved files can be identified by their suffixes: raw, absorbance, and analysis. By default, only raw data is saved.

Device Identification

Device identification information is automatically updated for every connected sensor. This screen displays sensor-specific identification data, such as the type and version of the sensor, serial number, manufacturing date and firmware version.

In this area, you can read the sensor temperature by pressing the READ TEMP button. The temperature reading will be updated as soon as the measurement cycle is finished.
