Test Conditions
The following setup and environmental conditions are required to ensure the NI 4113 meets
published specifications:
•
Keep cabling as short as possible. Long cables act as antennas, picking up extra noise that
can affect measurements.
•
Verify that all connections to the device, including front panel connections and screws,
are secure.
•
Ensure that the PXI chassis fan speed is set to HIGH, that the fan filters (if present) are
clean, and that the empty slots contain slot blockers and filler panels. For more
information about cooling, refer to the
Maintain Forced-Air Cooling Note to Users
document available at

If you make measurements using only one DMM, sequentially set up the DMM connections as
specified by the procedure steps.
