9.1 Getting Started
Until you are completely comfortable operating the EPOCH 1000 Series, we
recommend that a basic review and setup procedure be used prior to starting the
actual calibration.
To setup the EPOCH 1000 Series conventional UT mode before calibrating
1. Press [GAIN] to select an initial gain value that is appropriate for the calibration.
If the appropriate gain level is unknown, set the initial gain at 20 dB and adjust it
as necessary during calibration.
2. Choose 1/5 > Basic > Vel oc ity, and then enter an approximate velocity for the test
material. Refer to Appendix
A on page 321 for a table with sound velocities for
various materials.
The Velo city parameter is disabled when the instrument is in time-of-flight mode.
Select 3/5 > Meas Setup > Unit = mm or in to enable the Velo ci ty parameter.
3. Choose 1/5 > Basic > Zero, and then adjust the zero offset of the instrument to
0.000
µs.
4. Choose 1/5 > Basic > Range, and then set the range based on the sound path range
within the selected calibration block.
