Testing
Once a proper reference has been taken the instrument will continuously update the return loss value or insertion loss
value depending on what mode it is in. The OPM and IL screens will show the optical power reading and insertion loss
values, respectively, for both channels simultaneously. Each channel has its own return loss mode so that the distance
and the value can be displayed simultaneously.
