ComputationFunction
Equations can be defined in computation channels by using the measured data or
computed data as variables. The result of the computation can be displayed or stored.
For the setting procedure, see section 9.1.

computation
001.LT.002 The result is 1 when [001] is less than [002] or 0
otherwise.
001.LE.002 The result is 1 when [001] is less than equal to [002]
or 0 otherwise.
001.GT.002 The result is 1 when [001] is greater than [002] or 0
otherwise.
001.GE.002 The result is 1 when [001] is greater than equal to
[002] or 0 otherwise.
001.EQ.002 The result is 1 when [001] is equal to [002] or 0
otherwise.
001.NE.002 The result is 1 when [001] is not equal to [002] or 0
otherwise.
Logical computation 001AND002 The result is 1 when [001] and [002] are nonzero or
0 otherwise.
001OR002 The result is 1 when [001] or [002] or both are
nonzero or 0 otherwise.
001XOR002 The result is 0 when [001] and [002] are nonzero or
1 otherwise.
NOT001 The result is 1 when [001] is zero or 0 otherwise.
TLOG computation* TLOG.SUM(001) Determines the sum of [001].
TLOG.MAX(001) Determines the maximum value of [001].
TLOG.MIN(001) Determines the minimum value of [001].
