This function enables the user to adjust with ease the light axis of the through-beam fiber with the light source flashing. All E3X models have this
function.

2. If the axis of the light emission fiber head and that of the
light reception fiber head do not agree with each other
and the amount of light reception becomes 90% of the
peak value or less, the flashing function of the E3X will
work. The E3X retains the peak value when the mode
setting selector is set to FLASH and the axes of the
fiber heads are adjusted to agree with each other.
