Performing Measurements How to Adjust Gates/Threshold
The process of adjusting gates/threshold consists of:
Selecting the gates/threshold
Repositioning the gate location
Available Gates/Threshold
A gate delimits an event, such as the detection of the
cornea. There are four vertical gates and one horizontal
threshold along the horizontal and vertical axis of the
waveform. The gates/threshold are as follows:
Cornea Gate
Anterior Lens Gate (visible if the eye type is
not Aphakic)
Posterior Lens Gate (visible if lens thickness
is measurable)
Retina Gate
Threshold
The event being measured should be located to the right
of the gate and above the threshold. You can reposition
the gates/threshold if the events, gates and threshold do
not align properly.
