Integration time
It allows you to modify the gain during
acquisition. Increasing the integration time
increases the intensity, but moves the zero

Caution: increasing the integration time also
increases the noise intensity.
The checkbox next to the value lets you
manage integration time automatically or
manually. In manual mode (box unchecked),
you can enter the desired value directly in the
display field.

Black measurement
This function allows you to measure a
