Storing the Gated Reflector

You can store the gated reflector as the Ref B value.
To store a Ref B value
1. Use the GATES key to gate the echo from the reference-reflector. Move the probe
forward and backward to bring the echo to its maximum amplitude (peak), using
Peak Memory if necessary.
2. Press 2 ND F, (AUTO XX%) to bring the maximum peak of the gated echo to
reference height.
3. Choose AWS > Ref B to store the gated reflector as the Ref B value and choose
YES to confirm (see Figure 11-19 on page 252).
Once the Ref B value is stored, the instrument displays a live D rating of any gated
indication (see Figure 11-20 on page 253). This live D value, which represents the
defect indication rating used with the published "AWS Acceptance - Rejection
Criteria" tables to classify a potential flaw, can be viewed as a separate measurement
reading in one of the five boxes. To activate and view this measurement, see "Setup
Pages" on page 86.
