4.19 MAIN Menu
The MAIN key invokes the main menu and its parameters. The main menu contains
parameters that offer one touch storage and feature control.
GAIN See GAIN parameter description in the Receiver menu section.
FREEZE The FREEZE control activates and deactivates the freeze feature. The FREEZE
function will “freeze” the current A-Scan display and allow thickness measurement. Pressing
the PULSER, RCVR, RANGE, or SPCL key turns off the Freeze function.
ZOOM The ZOOM feature allows the operator to expand the contents of the gate 1 region to
full screen width. Toggle ZOOM off and on for the desired display.
T-STORE With this parameter highlighted, repeated presses of the T-STORE soft key store
the displayed thickness reading in the specified location and increment the location numbers.
The arrow key may be used to increase or decrease the storage location. The instrument will
not advance the location number beyond the limit of the block. To use T-STORE, T-gauge
must be on and a data logger block defined.
A-LOC The A-LOC function stores the displayed A-Scan in the specified storage location and
automatically increments the location number. If the selected location is FULL, the location
number will have an “(F)” next to it, the store operation will NOT take place, and an
“INVALID” indicator will be displayed on the status line. The instrument will not advance the
location number beyond the A-Scan storage limit of 100.
