Whenever sensor receives this command it supplies the latest measurement data to the host. If the laser is
switched off, it should be switched on by sending BM-Command (see section 7.2) before the measurement.
Laser should be switched off if necessary by sending QT-Command (see section 7.3) after measurement is
complete.
