Pv.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.

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

Usage:

DataCol = Pv.DataCol(ColumnCode)

DataCol ~ DATACOL ~ The new object containing the data extracted from the PV data array.

ColumnCode

  • INDEX
    • A code identifying the column to be used.
    • 0 = Time
    • 1 = Applied Forward Voltage
    • 2 = Applied Reverse Voltage
    • 3 = Applied Step Voltage
    • 4 = Measured Current
    • 5 = Measured Forward Current
    • 6 = Measured Reverse Current
    • 7 = Measured Current Difference between Ifwd and Irev.
    • 8 = Applied Signal
    • 9 = Measured Aux Channel Voltage
    • Or use the predefined constants:
    • PV_T = Time
    • PV_Vfwd = Applied Forward Voltage
    • PV_Vrev = Applied Reverse Voltage
    • PV_Vstep = Applied Step Voltage
    • PV_Im = Measured Current
    • PV_IFwd = Measured Forward Current
    • PV_Irev = Measured Reverse Current
    • PV_Idif = Measured Current Difference between Ifwd and Irev.
    • PV_Sig = Applied Signal (V)
    • PV_Ach = Measured Aux Channel Voltage
