Trigger range functions |
|
Increasing range value
- When the measured values of U and I exceed 110% of the rating
- When the peak value exceeds approximately 330% of the rating (or approximately 660% for crest factor 6)
Decreasing range value
- When the measured values of U and I fall to 30% or less range rating, and Upk and Ipk are 300% or less of the lower range value (or 600% for crest factor 6) |
