Nowadays,
the
eddy

testers
used
by
NDT
industries
are
either
with
too
big

or without

and
advanced
functions.
These
have
influenced
the applications
of
eddy

technology
in
aviati
on,
power,
petrochemical
and defense
industry.
With
the
improvement
of
electronic
component
integration,
especially
the creation
of
high-performance
data
acquisition
system
chip
and
low-power
LCD
monitor
as
well
as
high-energy
battery,
it
makes
the
design
of
small
and
hand-held
tester
become
more
and
more
possible.

probes
for
HEF-301:
Operation step for phase analysis of block defect
Instrument: HEF-301 eddy current tester
Probe: pencil probe with frequency 50k-500KHz
Block: Al block
Operation:
1. Select “DISP.”, and set “Disp.Mode” as “Line”.
2. Select “PARA.”, set “Freq.Val.” as 100KHz, “Filter” as 8, “Gain” as 40dB, “Lo.Pass” as 99.5Hz, other parameters as default.
3. Select “DEB.”, set “Pro.Gain” as 15dB, “Driver” as 3, other parameters as default.
4. Select “OTHE.”, set “Y/X Ratio” as 2.0 (usually the Y/X Ratio is between 2.0-5.0 for pencil probe, and 1.0 for welding probe), other parameters as default.
5. Exit by pressing three times of exit key. Press ↑ key to set the center point, a dialog box will come out. Press “OK”, and adjust the center point to the bottom right corner by pressing the four arrow keys.
6. Press Enter key to confirm. Place probe vertically on block area without defect, press BAL key and shake the probe, shaking signal will be on the screen. Select “ANAL.”, and adjust frame to select shaking signal. Adjust phase to make shaking signal to horizontal direction.
7. Enter into testing by pressing two times of exit key. Place probe on block area without defect. Shake the probe to see shaking signal on the level, and then scan the three cracks on the block.
