Verified 2026-10-24 Confidence: Medium

When a relay provides the optional reset characteristic of IEEE C37.112-2018, reset timing is checked at multiples of pickup below pickup, over the band that clause 3.4 names, using the reset equation of clause 3.2 with the reset constant scaled by the time dial.
