NI 6703/6704 Calibration Procedure for Traditional NI-DAQ 4 ni.com
Writing the Calibration Procedure
The calibration procedure in the Calibrating the NI 6703/6704 section
provides instructions for calling the appropriate calibration functions.
These calibration functions are C function calls from NI-DAQ that are also
valid for Visual Basic programs. Although LabVIEW VIs are not discussed
in this procedure, you can program in LabVIEW using the VIs that are
named similarly to the NI-DAQ function calls in this procedure. Refer to
the
Flowcharts section for illustrations of the code used at each step of the
calibration procedure.
Often you must follow a number of compiler-specific steps to create an
application that uses NI-DAQ. Refer to the
NI-DAQ User Manual for PC
Compatibles at
ni.com/manuals
for details about the required steps for
each of the supported compilers.
Many of the functions listed in the calibration procedure use variables that
are defined in the
nidaqcns.h
file. To use these variables, you must
include the
nidaqcns.h
file in the code. If you do not want to use these
variable definitions, you can examine the function call listings in the
NI-DAQ documentation and the
nidaqcns.h
file to determine what input
values are required.
Documentation
For information about NI-DAQ, refer to the following documentation:
• Traditional NI-DAQ Function Reference Help ( Start»Programs»
National Instruments»NI-DAQ»Traditional NI-DAQ Function
Reference Help
)
• NI-DAQ User Manual for PC Compatibles at
ni.com/manuals
These two documents provide detailed information about using NI-DAQ.
The function reference help includes information about the functions in
NI-DAQ. The user manual provides instructions on installing and
configuring DAQ devices and detailed information about creating
applications that use NI-DAQ. These documents are the primary references
for writing the calibration utility. For further information about the products
you are calibrating, you may also want to install the
PCI/PXI-6703/6704
User Manual .
Calibrating the NI 6703/6704
To calibrate the NI 6703/6704, complete the following steps:
1. Verify the performance of the NI 6703/6704. This step, which is
covered in the
Verifying the Performance of the NI 6703/6704 section,
confirms whether the device is in specification prior to adjustment.
