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:
• NI-DAQ Function Reference Help
( Start»Programs»National Instruments»NI-DAQ»NI-DAQ 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 on the functions in
NI-DAQ. The user manual provides instructions on installing and
configuring DAQ devices and detailed information on creating
applications that use NI-DAQ. These documents are the primary references
for writing the calibration utility. For further information on the device you
are calibrating, you may also want to install the device documentation.
Calibrating the NI 6711/6713/6731/6733
To calibrate the NI 6711/6713/6731/6733, complete the following steps:
1. Verify the performance of the NI 6711/6713/6731/6733. This step,
which is described in the
Verifying the Performance of the
NI 6711/6713/6731/6733 section, confirms whether the device is in
specification prior to adjustment.
2. Adjust the NI 6711/6713/6731/6733 calibration constants with respect
to a known voltage source. This step is described in the
Adjusting the
NI 6711/6713/6731/6733 section.
3. Re-verify the performance to ensure that the NI 6711/6713/6731/6733
is operating within its specifications after adjustment.
