f.
Call the niDMM Read VI.
•
For iterations containing the 0
measurement of each range,
store the result as the offset null for that range.
•
For all other iterations, subtract the previously stored offset
null for the corresponding range from the measurement taken.
g.
Verify that this measurement falls between the tolerances listed in
Table 23. Tolerances are provided instead of absolute limits
because your calibrator will have different discrete resistance
values.
5.
Repeat step 4 for each of the remaining iterations shown in Table 10.
