USB-1608HS User's Guide Installing the USB-1608HS

If the ACT LED turns off

If the ACT (active) LED lights up but then turns off, the computer has lost communication with the USB-

1608HS. To restore communication, disconnect the USB cable from the computer, and then reconnect it. This

should restore communication, and the LED should light up again.

Calibrating the USB-1608HS

The USB-1608HS is shipped fully-calibrated. Calibration coefficients are stored in EEPROM.

You can calibrate the analog inputs on the USB-1608HS with InstaCal. The normal calibration interval is once

per year.

Calibrate the device whenever the USB-1608HS's ambient temperature changes by more than ±10 °C. Allow

the USB-1608HS to warm up for at least 30 minutes before starting the calibration.
