KeyNotFoundException

Throw when the function key isn't found.

SetRange(object)

Sets the measuring range.

public void SetRange(object range)

Parameters

range object

A range as floating point value (e.g. 10.0 means from -10.0V to +10.0V), or a string representing a range: "AUTO", "MIN" or "MAX.
