Installing the Hardware
The DAQ Getting Started Guide contains non-software-specific
information about how to install PCI and PXI Express devices, as well as
accessories and cables.
Device Self-Calibration
NI recommends that you self-calibrate your S Series device after
installation and whenever the ambient temperature changes.
Self-calibration should be performed after the device has warmed up for the
recommended time period. Refer to the device specifications to find your
device warm-up time. This function measures the onboard reference
voltage of the device and adjusts the self-calibration constants to account
for any errors caused by short-term fluctuations in the environment.
Disconnect all external signals when you self-calibrate a device.
You can initiate self-calibration using Measurement & Automation
Explorer (MAX), by completing the following steps.
1.
Launch MAX.
2.
Select My System»Devices and Interfaces»NI-DAQmx
Devices»your device.
3.
Initiate self-calibration using one of the following methods:
•
Click Self-Calibrate in the upper right corner of MAX.
•
Right-click the name of the device in the MAX configuration tree
and select Self-Calibrate from the drop-down menu.
Note
You can also programmatically self-calibrate your device with NI-DAQmx,
as described in Device Calibration in the NI-DAQmx Help or the LabVIEW Help in
version 8.0 or later.
