NI 4071 7½-Digit FlexDMM Calibration Procedure
5.
Call the niDMM Self Cal VI.
Verification Procedures
You can use the verification procedures described in this section for both pre-adjustment and
post-adjustment verification. The verification procedures and the steps within them must be
performed in the order listed; however, you can opt to omit entire sections (for example, the
entire
section).
The parameters
Range
,
Resolution
, and
Sample
Interval
used in VI and function calls
throughout this section have floating point values. For example, if
Range
=
1
, the floating point
value is
1.0
. The parameters
Trigger Count
,
Sample Count
,
Array Size
, and
ParamValue
have integer values. Refer to the
NI Digital Multimeters Help
for more information about
parameter values.
Note
Many of the parameter values listed in this document are expressed in
scientific notation. Some programming languages do not support the direct entry of
numbers in this format. Be sure to properly enter these values with the appropriate
number of zeros. For example, you must enter the scientific notation number 10e–6
as
0.00001
and the number 100e3 as
100000
. If your programming language
supports numeric entries in scientific notation, NI recommends that you use this
feature to minimize possible data entry errors.
Verifying DC Voltage
To verify DC voltage of the NI 4071, complete the following steps:
1.
Plug in the insulated banana plug shorting bar across the
HI
and
LO
banana plug connectors
on the NI 4071.
2.
Wait one minute for the thermal EMF to stabilize.
3.
Call the niDMM Reset VI.
