(GEOMETRY)
QUANTITY
Select the units of measure:
TIME, ELONGATION, LOAD, STRESS or % STRAIN
LOAD FACTOR
The conversion factor from elongation to Load. This value is typically
determined by performing a field calibration and running a regression or
vector using the gauge or utility software. Alternatively, the load factor can
be determined using the bolt calculator in the Bolt Link software. How-
ever, if extreme accuracy is required, you must perform a field calibration.
You can edit this value at any time.
LOAD OFFSET
Normally LOAD OFFSET is set to zero. However, when a field calibration
is performed and regression calculated a small offset (y intercept) will
result. This value is a constant added or subtracted from the measure-
ment, and will result in correction to the load quantity. You can edit this
value at any time.
AREA
The cross sectional area of the fastener being measured. Used to convert
load to stress. Set to zero if QUANTITY is not set to STRESS. You can
edit this value at any time.
EFFECTIVE LEN.
The length of the region of the fastener under stress (the distance
between the nut plus some amount of additional stress that occurs in the
head and nut(s) of the fastener).
You can edit this value at any time.
DISP
(display)
VIEW
Choose between RF wave, RECT (rectified) wave and DIGITS (large dig-
its) views.
BACKLIGHT
Select OFF, ON, AUTO, or INVERT screen backlight.
CONTRAST
Adjust the screen contrast for variable light conditions.
DELAY
Adjust where the left side of the display window starts according to time
(which is converted to length), in millimetres or inches.
WIDTH
Set the overall depth of the viewable measurement area. It functions a lot
like a zoom on a camera.
TUNE
GAIN
Increases or decreases the overall amplitude of the signal.
Gain is similar to the volume control on a stereo receiver.
THRESHOLD
Sets the sensitivity level of the gauge. The amplitude of the signal must
reach or exceed this threshold level before a measurement is detected.
POLARITY
The gauge operates on a zero crossing detection principle. This feature
toggles which stroke of the cycle the crossing detection uses, either posi-
tive or negative.
PULSE
Your gauge has adjustable pulse width for both high penetration and res-
olution applications. The pulse width refers to the duration of time the
pulser is on. The options are SPIKE, THIN, and WIDE.
RECT WAVEFORM
Toggles between an outlined or filled view option when the display setting
is in RECT (rectified) wave mode.
AUTO
AUTO SET
Automatically locates the detection point if the measurement is out of the
viewable display area.
Used when measuring reference lengths only.
APPROX. LEN.
To use the AUTO SET function, an approximate length of the bolt must be
entered. The approximate length gives the gauge an indication of when to
switch on the receiver and look for the detection, or end of the bolt.
You can edit this value at any time.
MEASURE MODE
Select the measurement mode for different application requirements.
The mode options are:
P-E (pulse-echo)
P-E GT (pulse-echo with gate).
GATE
Sets the start of the gate, according to time/distance.
The gate allows you to view areas of the waveform and ignore others.
You can edit this value at any time.
