12.2 Display View Options
A key feature of the
BOLTSCOPE PRO
is the versatility of the display views
available to the user. The waveform views are a graphical representation of the
actual sound reflections traveling through a fastener and returning back to the
transducer. The waveform display shows the amplitude of the signal received on
the vertical (Y) axis and time (displayed in terms of length) on the horizontal (X)
axis. The two waveform display options are
RF
(Full) wave, and
RECT
(rectified)
half wave either positive or negative. These waveform options give the user the
ability to view the actual waveform and point of detection. In this view option the
user has better control over where the
BOLTSCOPE PRO
is detecting, selecting
the proper phase of the signal, and adjusting the gate and threshold (sensitivity)
to eliminate noise or to force a specific detection point.
The
RF
waveform view is recommended when initially setting up the
BOLTSCOPE PRO
for an application. This display view gives the user the ability
to view the entire waveform, both positive and negative cycles, to determine the
appropriate phase of the signal for measurement. The
Large Digits
display view
is a general digital display of the quantity selected. It’s a nice easy viewing
option that is typically used following setup of the initial application. The digits
view is also equipped with a limits bar that if the alarm status is activated and in a
measurement location other than an
L-REF
(reference length). If tolerance
values were setup in the
BOLTSCOPE PRO
, the user could use the limit bar and
alarm lights to view when the fastener was in the required tolerance region, and
avoid having to constantly watch the digital readout for a target value to appear.
