NOTE
This function is only available in SICAM P855.
The function Trend records ensures the acquisition and long-term monitoring of the voltage V
rms
(1/2-cycle)
values during voltage changes. The function Trend records compares the 1/2-cycle RMS value calculated from
measured value with last recorded 1/2-cycle RMS value in every 1/2 cycle. If the difference exceeds or falls
below the Tolerance number, the new 1/2-cycle RMS value is recorded.
