8.
Verify voltage measurement accuracy for each of the voltages listed in Table 18-2. For
each test point:
•
Select the correct Model 6514 measurement range.
•
Set the calibrator voltage to the indicated value.
•
Verify that Model 6514 voltage reading is within the limits given in the table.
9.
Repeat the procedure for negative source voltages with the same magnitudes as those
listed in Table 18-2.
