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

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.
