2.
Select the resistance calibrator external sense mode.
3.
For the Model 6430, select the auto ohms measurement method.
4.
Press MEAS
Ω
to select the ohms measurement function, and make sure the source out-
put is turned on.
5.
Verify ohms measurement accuracy for each of the resistance values listed in
Table 18-7. For each measurement:
•
Set the resistance calibrator output to the nominal resistance or closest available
value.
NOTE
It may not be possible to set the resistance calibrator to the specified value. Use the
closest possible setting, and modify reading limits accordingly.
•
Select the appropriate ohms measurement range with the RANGE keys.
•
Verify that the Model 6430 resistance reading is within the limits given in the
table.
