AWS
(American Weld-
ing Society)
AWS
Toggles AWS function ON or OFF.
This function is used in the analysis of welds according to
the American Welding Society’s structural welding code
D1.1-94 to calculate the Indication Rating (IR).
SET REF GAIN
The gain (in dB) required to set the indication level to a
specific percentage of full screen height (FSH).
% SCRN
HEIGHT
Set the reference level of the AWS as a percentage of full
screen height. This value will typically be set somewhere
between 20% to 90%.
TCG
(Time Corrected
Gain)
TCG
Toggles TCG function ON or OFF.
This function displays reflectors of equal size at equal
A-Scan amplitudes, regardless of the depth of the reflector
in the test material.
DRAW
Toggles DRAW mode ON or OFF and used to draw the
TCG curve.
CURVE
Toggles drawing of the TCG correction curve on the
screen ON or OFF.
% SCRN
HEIGHT
Set the reference level of the TCG as a percentage of full
screen height.
DAC
(Distance Ampli-
tude Correction)
DAC
Toggles DAC function ON, OFF or AUDIBLE.
A Distance Amplitude Correction (DAC) curve is used to
configure a variable threshold for the gate, using the same
size reflector at different distances.
DRAW
Toggles DRAW mode ON or OFF and used to draw the
TCG curve.
MEAS
Toggles the units displayed as a relationship of either the
signal amplitude and DAC curve, or just the signal
according to screen height. The units are %FSH, %DAC,
and dB.
CURVE
Selectable signal or multi DAC curve options. The
displayed curve options are: DAC, -2dB, -6dB, -10dB,
(-6dB/-12dB), (-6dB/-14dB). Once the DAC curve has
been generated, these options can be toggled at any time.
TRIGGER
Used to set the alarm threshold for the DAC curve. The
options are; at DAC, -2dB, -6dB, -10dB, -12dB, -14dB, or
using an independent gate. The list of trigger options will
change according to which CURVE option has been
selected.
DPOLARITY
Select the polarity of the DAC curves generated, either
positive
or negative.
DGS
New function to be released soon. Please contact Elcometer NDT for more
information.
