Four measurement modes are available: REF/KRT measurement, REF measurement
and KRT measurement and pupillometry can be selected.

REF/KRT measurement mode (R/K) : REF and KRT measurements are performed con-

tinuously.

REF measurement mode (REF)

: Only REF measurement is performed.

KRT measurement mode (KRT)

: Only KRT measurement is performed.

Pupillometry mode

: Brightness of the fixation target is changed and

pupil measurement is performed.

Tap the Mode button. A popup menu is displayed.
