Zero Set

The zero set test verifies that a minimal amount of residual offset error is present after zeroing has been performed. The offset error is caused by contamination from several sources including the noise of the power sensor module itself. Zero set is the difference between the power level indicated by the UUT—after executing zeroing—and true zero power. Ideally this difference should be zero.
