Table 105. Test equipment for calibrating the FD-11634
Instrument Recommended Model Requirements
Calibrator Fluke 5522A or 5560A Voltage source with gain uncertainty of <25 ppm and offset uncertainty of <94 μV in the 10 V range and <12 μV in the 1 V range.
SHM125M-Pigtail I/O Cable (0.3 m, 1 m, 3 m lengths) (x4) NI part number 785950-0R3/01/03 —
Banana Plug (optional) (x2) — Use banana plugs with an opening large enough to accommodate four 22 AWG signal wires

Test Conditions

The following setup and environmental conditions are required to ensure the FD-11634 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 device are secure.
  • Use shielded copper wire for all cable connections to the device. Use twisted-pairs wire to eliminate noise and thermal offsets.
  • 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 FieldDAQ device measurement circuitry is at a stable operating temperature.

Device Setup

To set up the device for calibration, complete the following steps:

  1. Set up the FD-11634 as outlined in the FD-11634 Quick Start.
    Note NI recommends that you use a dedicated Ethernet network adapter to connect the FD-11634 to a computer or controller. Use a second Ethernet network adapter for additional network access.
  2. Configure the hardware using Measurement & Automation Explorer (MAX).
  3. Launch the Calibration Executive procedure and complete the setup wizard.
Note If the device fails after calibration, return it to NI for repair or replacement.

Test Limit Equations

The following test limits are derived from the published specifications.

TestLimits = TestValue ± ( |TestValue| * [ppm of reading/1000000] + Range * [ppm of range/1000000] )
