Section 6. Data Table Declarations and Output Processing Instructions
Parameter
& Data Type Enter STDDEV PARAMETERS
Reps
Constant
The number of standard deviations to calculate. When repetitions are greater than 1, the source must be
an array.
Source
Variable
The name of the Variable that is the input for the instruction.
DataType A code to select the data storage format. Read More: See Section 4.2.4.4 Data Types
Constant Alpha Code Numeric Code Data Format
IEEE4 24 IEEE 4 byte floating point
FP2 7 Campbell Scientific 2 byte floating point
UINT2 21 2 Byte unsigned integer
Long 20 4 Byte Integer value
DisableVar
Constant,
Variable, or
Expression
A non-zero value will disable intermediate processing. Normally 0 is entered so all inputs are processed.
For example, when the disable variable is
≠0 the current input is not included in the standard deviation.
The standard deviation that is eventually stored is the standard deviation of the inputs that occurred
while the disable variable was 0.
Value Result
0 Process current input
≠ 0 Do not process current input
Totalize (Reps, Source, DataType, DisableVar)
The Totalize instruction is used to store the total(s) of the values of the
source(s) over the given output interval.
Parameter
& Data Type Enter TOTALIZE PARAMETERS
Reps
Constant
The number of totals to calculate. When repetitions are greater than 1, the source must be an array.
Source
Variable
The name of the Variable that is the input for the instruction.

DisableVar
Constant,
Variable, or
Expression
A non-zero value will disable intermediate processing. Normally 0 is entered so all inputs are processed.
For example, when the disable variable is
≠0 the current input is not included in the total. The total that
is eventually stored is the total of the inputs that occurred while the disable variable was 0.
Value Result
0 Process current input
≠ 0 Do not process current input
