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.
