QThe CT7040 series are rated to measure up to 6000A, but the current range of PQA is only 5000A. How can I measure up to 6000A?

A

The effective current measurement range of HIOKI PQAs is specified between 0% to 120% of range, and the accuracy is assured for that spectrum as well
So, the 5000A range will be able to measure up to 6000A within the accuracy specifications.
