C. Temperature – Indicates the current temperature of either the temperature
sensor, or manual value entered.
D. Feature Status Bar – Indicates the features currently enabled and in use:

Alarm

Quantity

Pulser Voltage

Q-Factor (wave correlation)
E. RF A-Scan Display (split screen) – Displays the radio frequency sound wave
reflection returned the opposite end of the bolt being measured. The RF view
displays both the positive and negative cycles.
F. Quantity – Displays the current quantity setting used (elongation, load, stress,
strain or time).
G. Digital Measurement – Display in inches, millimeters, KSI, KIPS, %strain,
time (nanoseconds).
H. Rectified A-Scan Display – Displays either the positive or negative half cycle
wave reflection returned from the opposite end of the bolt being measured,
depending on the polarity selected.
I. Time & Date – Feature to display either the time, date, or both time and date
on the main measurement screen.
J. Length Division Markers – Measurement scale of length.
K. Units – Displays the current measurement units being used (English, Metric).
L. Gain – The current gain setting can be adjusted at any time while in
measurement mode.
M. Temperature – Refer to (C) above. The location of the temperature is
displayed in this location when the hot menus are shown. Notice in (C) the
view is split screen and temperature is displayed in the top right corner of the
display. When the temperature mode is set ‘manual’, the value can be
changed at any time.
N. Digital Measurement – Display in inches, millimeters, KSI, KIPS, %strain,
time (nanoseconds).
O. Hot Menu items – We call this menu section our “hot menu”, as these items
are the most commonly adjusted features, requiring quick access from the
user. They can be displayed and scrolled by pressing the key at any
time. The key advances forward and the key backwards to the next
hot menu item.
P. Detect/Gate/Threshold – The broken dotted line demonstrates where the
MiniMax
is currently detecting on the waveform. Notice the horizontal line
with an arrow pointing at the detection point. This is the ‘gate’, and the height
of the line from the baseline is the ‘threshold’ level.
