ByVal scaleMin As Long, ByVal scaleMax As Long, ByVal
scalePoint As Long, ByVal iRange As Long) As Long
Parameters
daqmx Specify the device descriptor.
refChNo Specify the reference channel using a channel number.
startChNo Specify the start channel number.
endChNo Specify the end channel number.
spanMin Specify the span minimum.
spanMax Specify the span maximum.
scaleMin Specify the scale minimum.
scaleMax Specify the scale maximum.
scalePoint Specify the decimal point position for scaling.
iRange Specify the range type for the input of the target channel.
Description
• Sets the specified channel range to difference computation.
• If the minimum and maximum values of the span are equal, the span is
considered to be omitted.
• If the minimum and maximum values of the scale are equal, the scale is
considered to be omitted.
• The setup data is retrieved collectively, changed, and sent collectively.
• Channels from unsupported modules are ignored.
• The alarm setting is initialized.
• If, when specifying the input range for the target channel, “Reference range” is
specified for the range type, the same range as the reference channel is used for
