Description

Create and return an object of the class DATACOL.

The object is filed with data extracted from one column of the Pwr object's data array. The data, once extracted, can then be submitted to other objects for further calculation. For example, a class LINFIT object performs a linear regression analysis on two DATACOL objects.

A new DATACOL object is automatically created by the call to Pwr.DataCol(). It is usually transient, existing only for one function call.

Usage

DataCol = Pwr.DataCol(ColumnCode)

ColumnCode

INDEX

A code identifying the column to be used. Use the following Predefined constants:

•PWR_T = Time

•PWR_Vf = Applied Voltage

•PWR_Vu = Uncompensated Voltage

•PWR_Im = Measured Current

•PWR_Pwr = Measured Power

•PWR_R = Measured Resistance

•PWR_Temp = Measured Temperature

•PWR_IERange = IE Range used during measurement

•PWR_Ach = Measured Voltage Aux Channel

•PWR_Sig = Signal sent to Control Amp

•PWR_Over = Overload column

DataCol

DATACOL

The new object containing the data extracted from the PWR data array.
