Step 4:
Follow the instructions displayed, and press
below the
to change the displayed thickness reading
until it matches the known thickness. Note that you can
freeze the
A-scan during the calibration process.
Step 5:
When the displayed and known thicknesses match,
press
.
Step 6:
This process will determine the velocity at which
sound moves through the material being tested.
Step 7:
The calibration procedure has been completed. You
may resume testing or perform another procedure.
Performing the 2-PT Calibration Procedure
Step 1:
The 2-PT procedure must first be selected in the
TGMODE submenu (Section 3.3.1).
Step 2:
With a probe connected and properly identified
(Section 3.3.1), briefly press
.
Step 3:
The current (or default) value of the thinner (LO)
known-thickness calibration standard will be displayed.
Press
below
to change the displayed thickness
reading until it matches the known thickness. Note that this
is accomplished without coupling the probe.
CAUTION:
Closely follow the information given in this
section when choosing a calibration standard.
Step 4:
Couple the probe to the thinner (LO) known-
thickness calibration standard. Be sure to use couplant.
Step 5:
Follow the on-screen instructions and press
to store the calculated velocity measurement.
Step 6:
Uncouple from the thin calibration standard. Then
follow the on-screen instructions and repeat steps 4 and 5
using the thicker (HI) known-thickness calibration standard.
Step 7:
This process will determine the velocity at which
sound moves through the material being tested.
Step 8:
The calibration procedure has been completed. You
may resume testing or perform another procedure.
NOTE:
After performing the 2-pt. Calibration procedure, the
DMS 2 will remember the 2 point calibration thickness.
