Procedure
Repeat the following sequence for each range, starting with the 200 A range and
working up to the 20A range, as listed in Table 6-12.
1. Select the required 8508A range.
2. On the calibrator set the output to the current and frequency for the point being
verified as listed in Table 6-12. Set the output to
3. Note the 8508A reading. Compare the result with the allowable tolerance, taking into
account any known error from nominal of the calibrator for this output.
4. Repeat steps 2 – 4 for each point to be verified on the 8508A range to be verified.
5. Repeat steps 1 – 5 for each 8508A range to be verified.
6. Set the calibrator output to
