CreateVoltageRmsChannel

[zhangchang]

myTask.AIChannels.CreateVoltageRmsChannel(physicalChannelComboBox.Items[i].ToString(), "",

(AITerminalConfiguration)(-1), Convert.ToDouble(minimumValueNumeric.Value),
Convert.ToDouble(maximumValueNumeric.Value), AIVoltageAcrmsUnits.Volts);

Get the  following error

Who can tell me how to fix it，Thanks

Hi zhangchang,

I think you should try using myTask.AIChannels.CreateVoltageChannel instead of myTask.AIChannels.CreateVoltageRmsChannel. The error seems to indicate your device does not support that measurement type.
