Test Equipment

The following table lists the test equipment required for calibrating NI 9260.

Instrument Recommended Model Requirements
DMM PXI-4070 If this instrument is unavailable, use a multiranging 6 1/2-digit DMM with an accuracy of at least ±40 ppm.
Chassis cDAQ-9178

Test Conditions

The following setup and environmental conditions are required to ensure the NI 9260 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.
  • Use shielded copper wire for all cable connections to the device. Use twisted-pair wire to eliminate noise and thermal offsets.
  • Verify that all connections to the module are secure.
  • Maintain an ambient temperature of 23 °C ±5 °C. The device temperature will be greater than the ambient temperature.
  • Keep relative humidity below 80%.
  • Allow a warm-up time of at least 10 minutes to ensure that the NI 9260 measurement circuitry is at a stable operating temperature.

Device Setup

  1. Install the NI 9260 module in slot 8 of the cDAQ-9178 chassis. Leave slots 1 through 7 of the chassis empty.
  2. Configure the hardware using Measurement & Automation Explorer (MAX).
  3. Launch the Calibration Executive procedure and complete the setup wizard.
Note Note  If the NI module fails after calibration, return it to NI for repair or replacement.

Test Limit Equations

The following test limits are derived from the published specifications found in the NI 9260 Calibration Procedure.

Voltage Accuracy Verification

TestLimit = TestValue ± (TestValue * (GainError / 100) + (FS * (OffsetError / 100)))
