12.2 Display View Options
A key feature of the MiniMax 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 MiniMax 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 MiniMax for an
application. The user can consider either a full RF wave or split screen RF option.
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 is only
displayed when the alarm feature has been activated. The alarm limits are displayed
on the screen to give the user a visual idea of where they're at throughout the
fastening process. The alarm lights and beeper also work in conjunction with the
alarm limits and will display red until the lower limit is reached. Once the bolt stretch
is within the limits, the beeper will sound and the green light displayed.
