Math tool outputs can be sent out via a Communications tool and/or used as an input to a Test tool (or another Math
tool).
Multiple Operand Functions
Returns Min (X
1
, X
2
, ..., X
n
).
Returns the operand with the lowest value.
Min (Minimum)
Returns Max (X
1
, X
2
, ..., X
n
).
Returns the operand with the highest value.
Max (Maximum)
Returns Count (X
1
, X
2
, ..., X
n
).
Returns the count of operands.
Count
Returns Sum (X
1
, X
2
, ..., X
n
).
Returns the arithmetic sum of operands.
Sum
Returns Sum (X
1
, X
2
, ..., X
n
) ÷ Count (X
1
, X
2
, ..., X
n
).
Returns the mean value of operands.
Mean
The statistical median is middle number of a group of numbers that ha ve been arranged in order
by size. If there is an even number of terms, the median is the mean of the two middle numbers.
Median
The standard deviation and variance are measures of how spread out operands values are.
StdDev (Standard
Deviation) and
Variance
Use of Constants
In general, a user-defined constant can be selected as one of the Operands for the Math tool. This allows for a number
of things, including scaling the output of a vision tool in real units (by dividing that output by a known conversion
factor). Along the same lines, dynamic scaling of outputs is also possible by dividing one Operand by another and then
multiplying by a constant conversion factor. In this case, two Math tools would be used: one set for Division, the other
for Multiplication. The output of the first Math tool would be an Operand for the second Math tool.
Results
The output of the math operation selected for the inputs is diplayed in the results area of the Math tool Input tab.
Math Tool and the Remote Command Channel (RCC)
Description Syntax
Sets the specified tool operand, if it is a constant.
Value should be a floating number.
set mathtool tool_name|tool_number value operand_1|operand_2
Gets the value of the specified tool operand, if it
is a constant.
get mathtool tool_name|tool_number operand_1|operand_2
