1.9 Computation and Report Functions (/M1 and
/PM1 options)
Computation Functions
Expressions can be defined in special computation channels by using measured data or
computed data as variables. The computation channel data can be displayed or saved.
For configuration instructions, see section 10.1.

x
Relational
computation
001.LT.002 The result is 1 when [001] is less than [002] and 0
otherwise.
001.LE.002 The result is 1 when [001] is less than or equal to [002]
and 0 otherwise.
001.GT.002 The result is 1 when [001] is greater than [002] and 0
otherwise.
001.GE.002 The result is 1 when [001] is greater than or equal to [002]
and 0 otherwise.
001.EQ.002 The result is 1 when [001] is equal to [002] and 0
otherwise.
001.NE.002 The result is 1 when [001] is not equal to [002] and 0
otherwise.
Logical
computation
001AND002 The result is 1 when [001] and [002] are nonzero and 0
otherwise.
001OR002 The result is 1 when [001] or [002] is nonzero and 0 when
neither of them are.
001XOR002 The result is 0 when [001] and [002] are both zero or both
nonzero, and 1 otherwise.
NOT001 The result is 1 when [001] is zero and 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].
TLOG.AVE(001) Determines the average value of [001].
TLOG.P-P(001) Determines the difference between the maximum value
and minimum value of [001].
