APD Method
Selects the APD measurement method for the selected limit, either:
1. Disturbance Level: Compare a measured emission (E meas) against a limit emissions level (E limit) at a
specified probability value.
2. Probability of Time: Compare a measured probability level (ρ meas) against a limit probability (ρ limit)
level at a specified Emissions value.
