Spectrum

Spectrum mode is designed to represent the energy spectrum of photon radiation (X-ray and gamma).

In the Spectrum display mode, the screen represents:

status bar - at the top;

vertical graphic scale of the count rate - at the left;

histogram of the energy spectrum - at the center.

There are no rows in this table

⁠

There is a standard information of Display modes on the right side of status bar.

The following information is shown on the left side of status bar:

Linear scale of the amplitude of the energy spectrum of photon radiation.

Logarithmic scale of the amplitude of the energy spectrum of photon radiation.

Time from the beginning of spectrum accumulation: hours, minutes, seconds.

Using buttons

The following quick control options are available in this mode by using the buttons:

short press on the swing button "up" switches the scale of the spectrum amplitude between linear and logarithmic;

short press on the swing button "down" cyclically changes the scale of the energy spectrum: 1 MeV -> 2 MeV -> 3 MeV -> 1 MeV ...;

long press on the swing button "up" global turns on and off the sound signaling;

long press on the swing button "down" clears the spectrum histogram and starts a new accumulation session.
