  • NI-DAQmx

Issue Details

I am reading voltage on the Analog Input channel of my USB-6218. I set the voltage range to be 10 Volts max, but sometimes I get 10.2 Volts. Why am I able to get more voltage than what I specify?

Solution

While the Input Range of the USB-6218 can be set to 10 V, the working range of the device can go up to 10.4 V. This can be found in the spec sheet.
