Test Equipment
The following table lists the test instruments required for calibrating the PXIe-4322.
Instrument | Recommended Model | Requirements |
---|---|---|
DMM | Agilent HP 3458A | Use a DMM that can provide both voltage and current measurements. Accuracy in voltage of 165 ppm or better. Accuracy in current of 20 ppm or better. |
PXI Express Chassis | PXIe-1062Q | — |
Connection Accessory | TB-4322 | — |
Test Conditions
The following setup and environmental conditions are required to ensure the PXIe-4322 meets published specifications.
- Keep connections to the device as short as possible. Long cables and wires act as antennas, picking up extra noise that can affect measurements.
- Verify that all connections to the TB-4322 are secure.
- Use shielded copper wire for all cable connections to the device. Use twisted-pairs wire to eliminate noise.
- Maintain the ambient temperature between 23 °C ±5 °C.
- The PXIe-4322 temperature will be greater than the ambient temperature.
- Keep the relative humidity below 80%.
- Allow a warm-up time of at least 15 minutes to ensure that the PXIe-4322 measurement circuitry is at a stable operating temperature.
- 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. For more information, refer to the Maintain Forced-Air Cooling Note to Users document available at ni.com/docs.
Device Setup
- Install the PXIe-4322 in the PXI Express chassis according to the instructions in the NI PXIe-4322 and TB-4322 Installation Guide and Terminal Block Specifications.
- Configure the hardware using Measurement & Automation Explorer (MAX).
- Remove the exterior cover to expose the individual channel screw terminals as described in the NI PXIe-4322 Calibration Procedure.
- Ensure that the TB-4322 is correctly connected to the PXIe-4322; the terminal block will appear in the MAX Devices list below the PXIe-4322 module.
- Launch the Calibration Executive procedure. Calibration Executive guides you through the required connections.
Test Limit Equations
The following test limits are derived from the published specifications.
Equation Type | Equation |
