9.9.2
Operating in Standard Mode
Standard Mode is used when flaw detection is the main purpose of the application. The
EPOCH 4PLUS provides a digital thickness readout corresponding to the distance
between the echo detected in the Interface Gate and the echo detected in Gate 1.
Gate 1 and Gate 2 automatically track the Interface Gate based on the location of the echo
in the Interface Gate. The tracking distance is a result of the “Interface Gate blanking
period,” which is the distance between the Interface Gate start position and the Gate 1 start
position. Set this blanking period to optimize the inspection by ensuring that the proper
echoes are captured in the gates.
9.9.3
Operating in Echo-to-Echo Mode
Use the Echo-Echo Mode when thickness gaging is the main purpose of the application.
The EPOCH 4PLUS provides a thickness readout corresponding to the distance between
the echo detected in Gate 1 and the echo detected in Gate 2. The Echo-Echo is also capable
of ignoring the thickness associated with a painted or coated surface on the material.
Gate 1 automatically tracks the Interface Gate based on the location of the echo in the
Interface Gate. The tracking distance is a result of the “Interface Gate blanking period,”
which is the distance between the Interface Gate start position and Gate 1 start position.
Gate 2 automatically tracks Gate 1 based on the location of the echo in Gate 1. The
tracking distance is a result of the Gate 1 “blanking period,” which is the distance between
the Gate 1 start position and Gate 2 start position.
