  • Page 2: Verification

    17 Repeat the Verification section to determine the as-left status of the device. Required Software Calibrating the NI 4143 requires you to install the following software on the calibration system: • NI-DCPower. The NI 4143 was first supported in NI-DCPower 1.7.

  • Page 3: Test Conditions

    PTF65100K00BYEK sense Test Conditions The following setup and environmental conditions are required to ensure the NI 4143 meets published specifications: • Keep cabling as short as possible. Long cables act as antennas, picking up extra noise that can affect measurements.

  • Page 4: Calibration Overview

    Calibration Overview Calibration includes the steps shown in the following figure. is the internal device temperature recorded by the NI 4143 at the completion of the last self- calibration. Call the niDCPower Get Self Cal Last Temp VI to query T from the NI 4143.

  • Page 5: Self-Calibrating

    Verification or Return Device Complete Initial Setup—Install the NI 4143 and configure it in Measurement & Automation Explorer (MAX) . Verification—Verify the existing operation of the NI 4143. This step confirms whether the device is operating within the published specifications prior to adjustment.
  • Page 6 Compare a set of voltages measured by the external DMM to both a set of voltage test points requested by the NI 4143 and to the measured voltages reported by the NI 4143. Refer to the following table as you complete the following steps.

  • Page 7: Current Output And Measurement

    If more than one test point per level range is specified, repeat the previous steps for each test point, from setting the level to the test point on the NI 4143 up to this step. 10. If more than one level range is specified, repeat the previous steps using the values specified in each level range.
  • Page 8 0 mA 150 mA Set the first specified level range, limit range, and limit on the NI 4143. Set the level on the NI 4143 to the first specified test point. Take a current measurement using the DMM, and take a current measurement using the NI 4143.

  • Page 9: Remote Sense

    If more than one test point per level range is specified, repeat the previous steps for each test point, from setting the level to the test point on the NI 4143 up to this step. For zero current test points, disconnect all external equipment from the I/O connector on the NI 4143 and take a current measurement solely with the NI 4143, in order to ensure that the output current is zero.
  • Page 10 If more than one test point per level range is specified, repeat the previous steps for each test point, from setting the level to the test point on the NI 4143 up to this step. If more than one level range is specified, repeat the previous steps using the values specified in each level range.
  • Page 11 DC Current for the NI 4143. Verifying Current Remote Sense Accuracy Use the NI 4143 in constant current mode with a test circuit to simulate the voltage drop between the device and a load. Measure all of the specified resistors using the DMM before you connect equipment. Record the values.

  • Page 12: Adjustment

    If more than one test point per level range is specified, repeat the previous steps for each test point, from setting the level to the test point on the NI 4143 up to this step. If more than one level range is specified, repeat the previous steps using the values specified in each level range.

  • Page 13: Initiating The Adjustment Session

    DC Voltage for the NI 4143. Adjusting Voltage Measurement Compare a set of measured voltages reported by the NI 4143 to the voltages measured by an external DMM. You do not need to separately verify or adjust both measurement and output.

  • Page 14: Connecting And Configuring Equipment For Current Adjustment

    If more than one test point per level range is specified, repeat the previous steps for each test point, from setting the level to the test point on the NI 4143 up to this step. If more than one level range is specified, repeat the previous steps using the values specified in each level range.

  • Page 15: Adjusting Current Measurement

    If more than one test point per level range is specified, repeat the previous steps for each test point, from setting the level to the test point on the NI 4143 up to this step. For zero current test points, disconnect all external equipment from the I/O connector on the NI 4143 and take a current measurement solely with the NI 4143, in order to ensure that the output current is zero.

  • Page 16: Connecting And Configuring Equipment To Adjust Residual Offset Voltage

    Adjust Residual Voltage Offset VI or niDCPower_CalAdjustResidualVoltageOffset function. Adjusting Residual Current Offset Disconnect all equipment from the output of the NI 4143. Eliminate offset current at 0 A by configuring and calling the niDCPower Cal Adjust Residual Current Offset VI or niDCPower_CalAdjustResidualCurrentOffset function.
