    The following recommendations apply for all signal connections to your DAQCard: • • • DAQCard E Series User Manual Use differential analog input connections to reject common-mode noise. Use individually shielded, twisted-pair wires to connect analog input signals to the DAQCard. With this type of wire, the signals attached to the CH+ and CH- inputs are twisted together and then covered with a shield.

  • Page 81: Calibration

    Calibration This chapter discusses the calibration procedures for your DAQCard E Series card. If you are using the NI-DAQ device driver, that software includes calibration functions for performing all of the steps in the calibration process. Calibration refers to the process of minimizing measurement and output voltage errors by making small circuit adjustments.

  • Page 82: Self-Calibration

    Your DAQCard can measure and correct for almost all of its calibration-related errors without any external signal connections. Your National Instruments software provides a self-calibration method you can use. This self-calibration process, which generally takes less than a minute, is the preferred method of assuring accuracy in your application.

    3. Is there a way I can conserve power on my PC Card when it is not in use? Yes. If you are using NI-DAQ for PC compatibles version 4.8.0 or later, a utility called DAQPOWER.EXE will switch National Instruments PC Cards between normal mode and power-down mode. Run DAQPOWER from the command line to view instructions on the proper usage.
