NI 4065 Calibration Procedure
You have completed verifying AC current for the NI 4065. Select one of the
following options:
•
If you do
not
want to verify other modes
and
you are performing a
post-adjustment
verification, go to the
section.
•
If you do
not
want to verify any additional modes
and
you are
performing a
pre-adjustment
verification, call the niDMM Close VI or
the
niDMM_close
function to close the session.
Adjustment Procedures
This section explains how to adjust the NI 4065. You can choose to
perform these adjustment procedures with or without performing the
verification procedures first.
The parameters
Range
,
Resolution in Digits
,
Expected Measurement
,
and
Frequency
used in VI and function calls in this section have floating
point values. For example, if
Range
=
1
, the floating point value is
1.0
.
Refer to the
NI Digital Multimeters Help
for more information about
parameter values.
Note
NI recommends repeating the verification procedures, using the 24-hour accuracy
limits, after you perform these adjustment procedures. Reverification ensures the device
you calibrated is operating within specifications after adjustment.
