  • Page 2: Required Software

    Required Software Calibrating the PXIe-4136 requires you to install the following software on the calibration system: • NI-DCPower. The PXIe-4136 was first supported in NI-DCPower 15.1. • Supported application development environment (ADE)—LabVIEW or ™ ™ LabWindows /CVI • Supported operating system—Windows.

  • Page 3: Test Equipment

    Vishay PTF563K0000BYEB Remote sense 0.1% 250 mW accuracy Test Conditions Follow the setup and environmental information below to ensure the PXIe-4136 meets the published specifications. Test limits in this document are based on the June 2015 edition of the NI PXIe-4136 Specifications. •...

  • Page 4: Safety Guidelines For System Operation

    ±40 V DC, and is the internal device temperature recorded by the PXIe-4136 at the completion of the last self- calibration. Call the niDCPower Get Self Cal Last Temp VI to query T from the PXIe-4136.

  • Page 5: As-Found And As-Left Limits

    The as-left limits are equal to the published NI specifications for the device, less guard bands for measurement uncertainty, temperature drift, and drift over time. NI uses these limits to determine whether the device will meet the device specifications over its calibration interval.

  • Page 6: Verification

    You must complete all verification procedures in the specified order. You do not need to separately verify both measurement and output. The architecture of the PXIe-4136 ensures that if measurement is accurate, then output is as well, and vice versa. Related Information...

  • Page 7: Testing The Safety Interlock

    Disconnect or disable all connections to the PXIe-4136. Allow the PXIe-4136 30 minutes to warm up with the PXI chassis fans set to HIGH. Initialize an NI-DCPower session. Call the self-calibration function. Close the NI-DCPower session. Testing the Safety Interlock In order to ensure safe operation of the PXIe-4136, test the safety interlock for proper functionality before completing any verification procedures.

  • Page 8: Verifying Voltage Measurement And Output

    0.025% + 20 mV 0.0081% + 10 mV 200 V Set the first specified level range, limit range, and limit on the PXIe-4136. Set the niDCPower Sense property or NIDCPOWER_ATTR_SENSE attribute to Local. Measure the internal device temperature and perform self-calibration if necessary.

  • Page 9: Verifying Remote Sense Voltage Offset

    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 PXIe-4136 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 10 Sense HI Load1 Sense LO Set the first specified level range, limit range, and limit on the PXIe-4136. Measure the internal device temperature and perform self-calibration if necessary. If the internal device temperature exceeds T ±1 °C, wait up to five minutes for the temperature to stabilize to within T ±1 °C.

  • Page 11: Verifying Current Offset

    Load2 Sense LO Verifying Current Offset Remove all connections from the PXIe-4136 and confirm the current measured by the PXIe-4136 at 0 V falls within the test limits. Refer to the following table as you complete the following steps. Complete this procedure only after successfully completing all previous verification procedures.

  • Page 12: Verifying Load Regulation

    Note Although load regulation is listed as a typical specification for the PXIe-4136, verification is required. If the PXIe-4136 fails the load regulation verification procedure, discontinue use of the device and contact an authorized NI service representative to request a Return Material Authorization (RMA).

    Verify that the calculated DMM Measured Current value falls within the test limits. 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 PXIe-4136 up to this step. Adjustment This section describes the steps needed to adjust the PXIe-4136 to meet published specifications.

  • Page 19: Adjusted Specifications

    Note You do not need to separately adjust both measurement and output. The architecture of the PXIe-4136 ensures that if measurement is accurate, then output is as well, and vice versa. Initiating the Adjustment Session After completing verification, wait a minimum of five minutes for the internal device temperature to stabilize.
  • Page 20 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 PXIe-4136 up to this step. Update the output calibration constants by configuring and calling the niDCPower Cal Adjust Voltage Level VI or niDCPower_CalAdjustVoltageLevel function.
  • Page 21 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 PXIe-4136 up to this step. Adjusting the 100 µA and 1 mA level ranges automatically adjusts the following ranges: 1 μA, 10 µA, 10 mA, and 100 mA.
  • Page 22 Adjusting 1 A Current Output and Measurement Compare a set of measured currents reported by the PXIe-4136 to the currents measured by an external DMM. Refer to the following table as you complete the following steps.
