Documentation
The
NI-DAQ Function Reference Help
and the
NI-DAQ User Manual for
PC Compatibles
contain information on using NI-DAQ. The function
reference file includes detailed information on the functions in the driver.
The user manual provides instructions on installing and configuring
National Instruments DAQ devices and describes how to create
applications that use NI-DAQ. These documents are your primary
references for writing a calibration utility. For more information on the
products you are calibrating, refer to the device user manuals.
Software
NI-DAQ supports a number of programming languages, including
LabVIEW, Measurement Studio, Microsoft Visual C++, Microsoft Visual
Basic, and Borland C++. When you install NI-DAQ, install support for the
programming language you are using.
The
niECal.dll
,
niECal.lib
, and
niECal.h
files provide calibration
functions that are not provided by NI-DAQ. These functions include
protecting the calibration constants and updating the calibration date.
You can access the functions in this
.dll
through any 32-bit compiler.

The calibration process is described in the
section. The
description includes step-by-step instructions on calling the appropriate
calibration functions. Unless otherwise specified, the calibration functions
are C function calls in NI-DAQ. These function calls are also valid for
Visual Basic programs. While LabVIEW virtual instruments (VIs) are not
discussed, the translation from NI-DAQ function calls to LabVIEW VIs is
