6703/6704 Calibration Procedure

Installing NI-DAQ
Since 6703/6704 boards are PC-based measurement devices, you must
have the proper board driver installed in the calibration system before
attempting any calibration. For the 6703/6704 calibration procedure, you
will need the latest version of the National Instruments NI-DAQ driver
installed on the calibration system. This driver, which configures and
controls the DAQ device, is available at
www.natinst.com
.
The driver supports a number of programming languages, including
LabVIEW, LabWindows/CVI, Microsoft Visual C ++, Microsoft Visual
Basic and Borland C ++. When you install the driver, you need only install
support for the programming language that you intend to use.
For documentation that explains the use of the driver, install the following
PDF files:
•
NI-DAQ Function Reference Manual for PC Compatibles
•
NI-DAQ User Manual for PC Compatibles
These two manuals provide detailed information on using the NI-DAQ
driver. The function reference manual includes information on the
functions in the driver. The user manual provides instructions on installing
and configuring National Instruments DAQ devices and detailed
information on creating applications that use the NI-DAQ driver. These
manuals will be your primary references for writing your calibration utility.
For further information on the products you will be calibrating, you may
also want to install the device user manual.
You will also need a copy of the
ni6704Cal.dll
,
ni6704Cal.lib
, and
ni6704Cal.h
files. The
.dll
provides calibration functionality that does
not reside in the standard NI-DAQ driver, including the ability to protect the
calibration constants, update the calibration date, and write to the factory
calibration area. The factory calibration area and the calibration date should
only be modified by a metrology laboratory or another facility that
maintains traceable standards. You can access the functions in this
.dll
through any 32-bit compiler. These files are available on the National
Instruments Web site at
