when repeatedly pressed, will toggle through specific parameter settings (discrete steps). The
first time a
soft key is pressed, the parameter located in the display box directly above the key
will be highlighted using inverse video.
4.5 INC/DEC Arrow Keys
The Increase/Decrease arrow keys may also be used to change parameter settings. The
parameter being adjusted will be displayed in inverse video directly above one of the menu soft
keys. Holding these keys down will cause the rate of adjustment to be increased over time.
4.6 Main Menu Keys
Referring to the front panel view, the PULSER, RCVR, RANGE, GATE 1, GATE 2, THICK,
ANGLE, SPCL, DAC, and MAIN keys are all used to select menus. The parameter to be
adjusted or selected is shown in inverse video above one of the five soft keys. The
microprocessor keeps track of which parameter was last adjusted for each menu. It then returns
the operator to that parameter when the menu key is struck again after moving to a different
menu. The following sections show the different menus and briefly describe the parameters in
each.
There are ten types of menu keys associated with normal inspection procedures that may be
displayed in the soft key Display. Each menu key contains up to five parameters associated
with instrument operation which may be adjusted. The ten primary menus are organized so that
the most important instrument parameters are accessible within two key presses. The SPCL
menu contains a grid of less frequently adjusted parameters.
