To set a minimum depth alarm

2. Position the gate to cover the desired area.
3. Select 2/5 > Gate<n> > Alarm = MinDep.

less than the gate width value.
6.9.4 Minimum Depth Alarm with Gate Tracking
The EPOCH 1000 Series can use the minimum-depth alarm when making echo-to-
echo thickness measurements with gate tracking. When gate tracking is active, the
tracking gate moves side-to-side, tracking the position of the echo in the non tracking
(first) gate. With gate tracking active, the Min Depth alarm threshold is relative to the
position of the echo in the non tracking gate (first gate).
To set up a minimum depth alarm with gate tracking, follow the steps described in
section
6.9.3 on page 121.
