Software

Calibrating the NI 9216/9226 requires the installation of NI-DAQmx 14.5 or later on the
calibration system. You can download NI-DAQmx from
supports LabVIEW, LabWindows
Basic .NET, and Microsoft Visual C#. When you install NI-DAQmx you only need to install
support for the application software that you intend to use.

    • Keep relative humidity below 80%. • Allow a warm-up time of at least 10 minutes to ensure that the NI 9216/9226 measurement circuitry is at a stable operating temperature. Initial Setup Complete the following steps to set up the NI 9216/9226.

  • Page 4: Verification

    Complete the following procedure to determine the As-Found status of the NI 9216/9226. Set the calibrator to Standby mode (STBY). Connect the desired channel of the NI 9216/9226 to the calibrator as shown in Figure 1. Connect only one channel at a time.
  • Page 5 Note Set the calibrator to Operate mode (OPR). Acquire and average samples from one channel. Create and configure a 4-wire AI resistance task on the NI 9216/9226 according to Table 3. Configure the ADC Timing Mode to High Resolution. Table 3. NI 9216/9226 Voltage Configuration...

  • Page 6: Adjustments

    Complete the following procedure to adjust the accuracy performance of the NI 9216/9226. Set the calibrator to Standby mode (STBY). Connect the desired channel of the NI 9216/9226 to the calibrator as shown in Figure 1. Connect only one channel at a time.

  • Page 7: Eeprom Update

    EEPROM Update When an adjustment procedure is completed, the NI 9216/9226 internal calibration memory (EEPROM) is immediately updated. If you do not want to perform an adjustment, you can update the calibration date and onboard calibration temperature without making any adjustments by initializing an external calibration, setting the C Series calibration temperature, and closing the external calibration.
