Installing the USB-1608FS-Plus

8

If the LED turns off

If communication is lost between the device and the computer, the device LED turns off. To restore
communication, disconnect the USB cable from the computer and then reconnect it. This should restore
communication, and the LED should turn on.

Calibrating the hardware

The Measurement Computing Manufacturing Test department performs the initial factory calibration. Return
the device to Measurement Computing Corporation when calibration is required. The recommended calibration
interval is one year.

The USB-1608FS-Plus does not support field calibration.
