ChronoA.DataCol()

Type: INSTANCE FUNCTION

Purpose: Create and return an object of the class DATACOL.

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

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

Usage:

DataCol = ChronoA.DataCol(ColumnCode)
     
DataCol DATACOL The new object containing the data extracted from the CHRONOA data array.
ColumnCode INDEX

A code identifying the column to be used.

0 = Time

1 = Applied Voltage

2 = Uncompensated Voltage

3 = Measured Current

4 = Signal sent to Control Amplifier

5 = Measured Aux Channel Voltage

6 = I/E Range used

7 = Overloads

Or use the predefined constants:

CHRONOA_T = Time

CHRONOA_Vf = Applied Voltage

CHRONOA_Vu = Uncompensated Voltage

CHRONOA_Im = Measured Current

CHRONOA_Sig = Signal sent to Control Ampllifier

CHRONOA_Ach = Measured Aux Channel Voltage

CHRONOC_IERange = I/E Range Used

CHRONOA_Over = Overloads
