Test Equipment

The following table lists the test equipment required to calibrate the PXIe-4353 device.

Table 155. Test equipment for calibrating the PXIe-4353
Instrument Recommended Model Requirements
Voltage calibrator Fluke 5520A If this instrument is unavailable for voltage accuracy verification and adjustment, use a high-precision voltage source with an accuracy of at least 70 ppm when sourcing up to 50 µA.
Resistance calibrator* Fluke 5520A If this instrument is unavailable for resistance accuracy verification and adjustment, use a high-precision resistance source with an accuracy of at least 150 ppm 2-wire compensation.
PXI Express chassis PXIe-1062Q —
Calibration accessory CAL-4353 This accessory is used for module verification and adjustment.
Connecting wires Banana-jack terminated copper wire Copper wire is used for validating the voltage accuracy and adjustment of the analog input channels. Copper wire is also used for validating the resistance accuracy and calibration of the CJC resistance input channels.
Note *When connecting the resistance calibrator, keep the lead wires 1.0 Ω less than the maximum lead compensation specification of the resistance calibrator. When using the Fluke 5520A, keep the lead wires <1.1 Ω.
Note Though the Fluke 5500 has specifications matching those named in the PXIe-4353 Calibration Procedure, there are physical interactions of the DUT which cannot properly read resistance values sourced by this calibrator at all test points.

Test Conditions

The following setup and environmental conditions are required to ensure the PXIe-4353 meets published specifications.

  • Keep connections to the PXIe-4353 device as short as possible. Long cables and wires act as antennas, picking up extra noise that can affect measurements.
  • Use shielded copper wire for all cable connections to the device. Use twisted-pair wire to eliminate noise and thermal offsets.
  • Maintain an ambient temperature of 23 °C ±5 °C. The module temperature will be greater than the ambient temperature.
  • Keep relative humidity below 80%.
  • Allow a warm-up time of at 15 minutes to ensure that the measurement circuitry of the PXIe-4353 and CAL-4353 are at a stable operating temperature.
    Note If you are using the Fluke 5520A, allow the calibrator to warm up for 30 minutes and maintain an ambient temperature of 23 °C ±3 °C. Refer to the Fluke 5520A user manual for the latest set up requirements and recommendations to achieve the best accuracy.
  • Temperature change affects the measurement characteristics of an instrument. To take these changes into account, the tested specifications include the effects of temperature drift. For the PXIe-4353, valid temperature drift is ±10 °C.
  • Ensure that the PXI Express chassis fan speed is set to HIGH, that the fan filters are clean, and that the empty slots contain filler panels.

Device Setup

To set up the PXIe-4353 for calibration, complete the following steps:

  1. Install and configure the PXIe-4353 module with Measurement & Automation Explorer (MAX). Refer to the Measurement & Automation Explorer Help for DAQ for more configuration information.
  2. Attach the CAL-4353 to the PXIe-4353 so that the connection pane is flush with the chassis and tighten the connection screw. Ensure the connection between the two devices is stable by confirming that MAX shows the CAL-4353 in the PXIe-4353 device drop down list.
  3. Launch the Calibration Executive procedure. Calibration Executive guides you through the required connections.
