NOTE
Operators (For details, see Section Appendix.3.9.)
･ If the calculable maximum recording length is set, calculation formulas Z1 to
Z8 are enabled. If recording length is less than half the calculable maximum
recording length, calculation formulas Z1 to Z16 are enabled.
･ For multiplication, always use the "
*
" sign.
･ Out of the MOV, SLI, DIF, DIF2, INT, and INT2 operators, up to four can
be used in the same equation (for example four MOV operators or two MOV
and two SLI operator, etc.).
･ The maximum number of digits for a constant is 30.
･ If division by 0 is specified (1/0), an overflow value is output.
･ Equations are calculated in ascending order, from Z1 to Z16.
･ The data that can be used in an operational equation (channel data and
results of operation) must be smaller than in the preset operation numbers
(for example, Z10 cannot be used on Z8).
･ Up to eighty characters can be entered in an operational equation. However,
only the first line of the expression is displayed on the waveform operation
screen.
