REF/CAL FULL. The REF/CAL FULL control saves the currently displayed
STORE or VIEW curve in the reference waveform memory and displays the
entered curve as a REF (reference) curve. The STORE or VIEW curve can be
displayed together with the REF curve.
If the SAVE button is pressed while the REF curve is displayed, it is saved along
with front panel settings as part of the setup. The REF curve remains on the CRT
until the REF button is pressed again or NON STORE display mode is selected.
Pressing the REF button while holding down the FAST/SHIFT button changes
button function to CAL FULL, which displays a dot in the upper right corner of
the screen.
The CAL FULL dot provides a reference for checking the CRT deflection at the
10th graticule lines (vertical and horizontal).
While in the calibration mode, “CAL” is displayed in the upper right corner of
the display graticule.
VIEW. The View control displays the previously entered curves from the mass
storage. The Memory Index display indicates the display curve identification
number. The CURVE ID number is displayed at the bottom right corner of the
CRT for about 5 seconds and is then automatically erased. If any setting (except
REF) is changed while in the ViEW mode, the display mode is changed to the
STORE mode automatically to reflect the setting change result.
If the VIEW button is pressed while holding down the FAST/SHIFT button, the
function of this button changes to COPY. This copy function can be used to copy
simultaneously up to 16 characteristic curves and up to 16 front-panel setups
from floppy disk to non-volatile IC memory.
Before using this function, the MEMORY buttons must be set to the starting
position in memory for the source of the data to be copied.
If the VIEW button is pressed while holding down the FAST/SHIFT button, the
“PRESS VIEW” message is displayed for approximately five seconds. If the
VIEW button is pressed during this period, copying begins. If the VIEW buttons
is not pressed, the function is cancelled, and the “COPY CANCELLED”
message is displayed. Copying starts with the characteristic curve data, followed
by front panel setup data. Copying of curve data starts by writing this data at the
specified starting position in memory position number 1, followed by the next
curve data being copied into memory position number 2, and so on.
At the point at which 15 curves are written from floppy disk into non-volatile IC
memory, the copying of the curve data is terminated. However, should the
number of stored curves be less than 16 when the memory position for identifier
number 80 is reached, the copying of the curves is completed when all the curves
are copied. In this case, all the contents stored into IC memory will not be
