Step 4:
If you select the AUTO zeroing procedure, the instru-
ment will zero the probe on its own. If instead you selected
manual zeroing, zero the instrument-probe combination by
using the following procedure.
•
With the probe uncoupled (not touching any material),
press
.
•
Couple the probe’s measurement surface (after applying
couplant) to the ZERO BLOCK on the front of the DMS 2.
•
The instrument display will indicate when the zeroing
process is complete.
NOTE:
Couplant must be used between the measurement
surfaces of all probes and the material being tested. Thickness
readings can not be obtained without the use of couplant.
Step 5:
Determine the material velocity by performing a one-
point calibration. Note that while the default velocity setting
represents common steel (0.2313
×
10
6
inches per second),
you must calibrate the instrument to match the specific
material that you’re inspecting.
In
Step 3
, you selected the dual
measurement mode. Most probes will allow you to perform a
one-point calibration and operate in this mode. See Sections
3.3.1 and 3.3.4 for additional calibration options. Otherwise,
use the following procedure to calibrate your instrument.
