Property: Offset for ProcessedChannel

Property: Offset for ProcessedChannel

Specifies the offset that is added when a value is read.

This property, used with the Factor property, can be used to calibrate values as they are read in. The formula for conversion is as follows:

Value = Factor*File value + Offset.

Object.Offset

Note  The properties Factor and Offset are ignored when text channels and time channels are read. For all other channel types, the conversion formula returns a Real result.

The following example generates a new MyChannel channel in the Measurements channel group. The new channel contains the values added rowwise of the second, third, and fourth channels of the Measurements channel group. Each value of the MyChannel channel is also multiplied by the factor 2 and then the offset 5 is added.

Dim oChannelGroup, oProcessedChn, i
Set oChannelGroup = Root.ChannelGroups("Measurements")
Set oProcessedChn = oChannelGroups.Channels.AddProcessedChannel("MyChannel",eR64,eAddProcessor)
oProcessedChn.Factor = 2
oProcessedChn.Offset = 5
For i = 2 to 4
  Call oProcessedChn.Channels.Add(oChannelGroup.Channels(i))
