Automatic setting
After calculation, the upper and lower limit is determined from the result,
and the variable display settings are made accordingly.
Depending on the type of calculation, automatically display scale setting may
not be satisfactory. In such a case, use the manual setting procedure.
Manual setting
Use the variable display setting function on the VARIABLE screen to set the
upper and lower limit and units. (See Section 5.2.)
Calculation result with overflows
The values shown using cursors A and B and the printed values obtained
when the printer recording type is set to "numerical value" are not accurate.
If the display scale is set to "AUTO," the waveform is shown at the top or
bottom of the screen. This indicates that the calculation result has
overflowed.
Calculation Result Units
There is no specified unit for calculation results, but you can assign one by
turning on the scaling setting for the channel being recorded. For details on
the scaling function, see section 5.3.
