Parameter
& Data Type Enter
DataType A code to select the data storage format.
Constant Alpha Code Numeric Code Data Format
IEEE4 24 IEEE 4 byte floating point
FP2 7 Campbell Scientific 2 byte floating point
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
checked for a new minimum. The minimum that is eventually stored is the minimum that
occurred while the disable variable was 0.
Value
Result
0 Process current input
≠
0 Do not process current input
Time Option to store time of Minimum. When time is output, the minimum values for all
repetitions are output first followed by the times at which they occurred.
Constant Value Result
0 Do not store time
1 Store time

Parameter
& Data Type Enter
Source
Variable The variable that is tested to determine which bin is selected
DataType A code to select the data storage format.

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 histogram. The histogram that is eventually stored includes the inputs that
occurred while the disable variable was 0.
Value
Result
0 Process current input
≠
0 Do not process current input
MeanBins
Constant
This parameter allows sorting by the mean value of the signal during a stress strain cycle.
The number entered is the number of bins or subranges to sort the mean values into.
Enter 1 to disregard the signal value and only sort by the amplitude of the signal. The
width of each subrange is equal to the HiLimit - LowLimit divided by the number of bins.
The lowest bin’s minimum value is the low limit and the highest bin’s maximum value is
the High limit
AmpBins
Constant
The number of bins or subranges to sort the amplitude of a stress strain cycle into. The
width of each subrange is equal to the HiLimit - LowLimit divided by the number of bins.
LowLim
Constant
The lower limit of the input signal and the Mean Bins.
UpLim
Constant
The upper limit of the input signal and the Mean Bins.
MinAmp
Constant
The minimum amplitude that a stress strain cycle must have to be counted.
