8.3 MAIN MENU ITEM OPERATION
If in Impedance Plane-Resonance Mode
8.3.1 DOTS
•
Dots selects a sub menu where screen position is stored for up to 8 places. A
ring, square or elliptical gate can then be set, sized and an alarm can be
activated for that gate. The following are the sub gate functions
•
DOT# - Activates a specific dot to work on when multiple dots have been set
on screen.
•
STORE – Sets the current flaw screen position when pressed and identifies it
by applying a number to the location. Once set, the DOT# will auto increment
to DOT#2 and so on.
•
ERASE – Erases the selected DOT#. Renumbers any dot over the number
selected if they exist.
•
GATE – Selects gate type. Either RECT, ELIPSE or OFF
•
WID – Gate Width. Makes the gate wider or narrower.
•
HT – Gate Height. Increases or decreases gate height.
NOTE: A relative number is displayed in the status line below the active screen to aid is setup. A square gate would be had by selecting equal WID
& HT
NEXT ROW
•
X – Manually sets the X or horizontal position of the selected DOT#
•
Y – Manually set the Y or vertical position of the selected DOT#
•
ANGLE – Sets the DOT’s angle
•
ALM – Sets alarm trigger to either IN or OUT of the selected gate geometry
•
BUZZ – Turns the Audible alarm ON or OFF
•
CLEAR – Clears ALL Reference DOTS from the screen to start over.
•
ROT – Rotates the screen with the DOTS following in tact to allow for optimal positioning of DOT geometry
with reference to screen location
·
In this image example, the screen has the same stored dot positions as “Resonance 1 - Dot Screen” except the
screen has been optimized to allow for increase in scale by repositioning the NULL
cross hair to a more lower left position. The SCALE could then be increased and, one
of the GATES was set to elliptical. These functions are generally not offered in
competitive instruments.
8.3.2 FREQ - FREQUENCY
Permits manual adjustment of frequency. Nominal frequency is set when probe is
attached. Balanced Frequency is set at any user selected balance interval.
8.3.3 ROT – ROTATE
Rotates the screen with the DOTS following in tact to allow for optimal positioning of DOT
geometry with reference to screen location
