If the LED turns off
If the LED is illuminated but then turns off, the computer has lost communication with the USB-1408FS. To
restore communication, disconnect the USB cable from the computer, and then reconnect it. This should restore
communication, and the LED should turn back on.
Allow the USB-1408FS to operate for at least 30 minutes before using the device. This warm up time is
required to achieve the specified rated accuracy of measurements.
