Light Axis Adjustment with Flashing Function

E3X-T

jj

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.

1. Set the mode setting selector to FLASH.

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.
