• DA - Material-thickness depth from the probe-contacted side of the test-piece surface to the reflector, represented by the Gate A echo.
• DB - Material-thickness depth from the probe-contacted side of the test-piece surface to the reflector, represented by the Gate B echo.
• LA - Leg number of the reflector, represented by the Gate A echo.
• LB - Leg number of the reflector, represented by the Gate B echo.
• PA - Projection distance from the probe BIP to the reflector, represented by the Gate A echo.
• PB - Projection distance from the probe BIP to the reflector, represented by the Gate B echo.
• RA - Projection distance from the probe BIP to the reflector, represented by the Gate A echo, minus the current X-VALUE.
• RB - Projection distance from the probe BIP to the reflector, represented by the Gate B echo, minus the current X-VALUE.
• A%rA - Amplitude of the signal crossing Gate A, as a percentage of the active EVAL MODE reference amplitude.
• A%rB - Amplitude of the signal crossing Gate B, as a percentage of the active EVAL MODE reference amplitude.
• dBrA - dB equivalent height difference between the signal crossing Gate A and the active EVAL MODE reference height.
• dBrB - dB equivalent height difference between the signal crossing Gate B and the active EVAL MODE reference height.
