16.2 Calculating Waveform Data
────────────────────────────────────────────────────
When the equations have been input, pres
s
the F5 [ exit ] key. If there are any syntax
errors in the equations (incomplete
bracketing, missing "
*
", more than eight
MOV, SLI, DIF, DIF2, INT, INT2
operators, etc.), a "?" is displayed, and the
cursor rests on the error, so that the
problem can be corrected. When there are
no syntax errors, a "=" is displayed.
Make settings for Z2 to Z16 as for Z1.
ABS Absolute value DIF2 2nd differential
EXP Exponential INT2 2nd integral
LOG Logarithm SIN Sine
SQR Square root COS Cosine
MOV Displacement average TAN Tangent
SLI Parallel displacement o
n
time axis
ASIN Arc-sine
DIF 1st differential ACOS Arc-cosine
INT 1st integral ATAN Arc-tangent
NOTE
Operators (For details, see Section 21.3.9.)
・For multiplication, always use the "
*
" sign.
・Out of the MOV, SLI, DIF, DIF2, INT, and INT2 operators, up to eight can
be used in the same equation (for example eight MOV operators or five
MOV and three 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.
