The measurement is the delta frequency divided by the delta time where the setting can be
either a ramp rate or a step function as selected.

For electro-mechanical relays, a single set point, time dial, and a step function are required.

For the solid state relay, multiple set points may be used in conjunction with multiple times
plus a step or ramp function.
