Connecting the USB-3110 to your system
To connect the USB-3110 to your system, turn your computer on, and connect the USB cable to a USB port on
your computer or to an external USB hub that is connected to your computer. The USB cable provides
communication to the USB-3110.
When you connect the USB-3110 to a computer for the first time, a Found New Hardware dialog opens when
the operating system detects the device. When the dialog closes, the installation is complete. After the
USB-3110 is installed, the USB LED should flash and then remain lit. This indicates that communication is
established between the USB-3110 and your computer.
Caution! Do not disconnect any device from the USB bus while the computer is communicating with the
USB-3110, or you may lose data and/or your ability to communicate with the USB-3110.
If the USB LED turns off
If the USB LED is illuminated but then turns off, the computer has lost communication with the USB-3110. 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.
Calibrating the USB-3110
The USB-3110 is shipped fully calibrated. Calibration coefficients are stored in the device FLASH memory.
Return the device to Measurement Computing Corporation when calibration is required. The normal calibration
interval is once per year.
