Auto
Used to automatically set the PRF value based on the chosen screen range.
Manual
Used to manually set the PRF value.
To adjust the PRF value in Manual PRF Mode
1.
Select
Pulser > PRF Mode = Manual
.
2.
Select
PRF
, and then adjust the PRF in either coarse or fine increments.
The EPOCH 650 is a
single-shot
instrument. This means that the instrument acquires,
measures, and draws the complete A-scan with each pulse rather than using multiple
acquisitions to construct a full waveform. The measurement rate in the EPOCH 650 is
always equal to the PRF rate unless you are using a multiplexer.
5.4.2
Pulse Energy (Voltage)
The EPOCH 650 ultrasonic flaw detector can adjust the pulse energy from 0 V to
400 V in increments of 100 V. With this flexibility, you can set the pulse energy from to
a minimum when you want to extend the battery life, or provide a very high power
pulser for the most difficult materials.
To adjust the pulser energy
Choose
Pulser > Energy
, and then vary the value. In the
Energy
adjustment,
coarse and fine steps are equal (100 V).
To maximize instrument battery life and transducer life, it is recommended that you
use lower energy settings when the application permits. For most applications, the
energy setting does not need to exceed 200 V.
