Software
The SCXI-1520 calibration procedure requires the latest version of the
NI-DAQ driver on the calibration system. The driver supports a number
of programming languages, including LabVIEW, Measurement Studio,
Microsoft Visual C++, Microsoft Visual Basic, and Borland C++. When
you install the driver, you need to install support only for the programming
language you are using.
Documentation
The
NI-DAQ Function Reference Help
and the
NI-DAQ User Manual for

Test Conditions
Follow these guidelines to optimize the connections and the environment
during calibration.
•
Keep connections to the SCXI module short. Long cables and wires act
as antennae, picking up extra noise and thermal offsets that can affect
measurements.
•
Use shielded copper wire for all cable connections to the device.
Use twisted-pair wire to reduce noise.
•
Maintain the temperature between 18 and 28 °C.
•
Keep relative humidity below 80%.
•
Allow a warm-up time of at least 15 minutes for the SCXI module
and 30 minutes for the DAQ device to ensure that the measurement
circuitry is at a stable operating temperature.
