Min./max. Worst min. and max. with phase indication for Voltages,
Currents, Voltage unbalance, and THD. Min. and max.
values for power factor (True and Displacement), power
(P, Q, S) and frequency
One event log Time stamping to 1 second
Trend curves (PM850 only) Four trend curves: 1 minute, 1 hour, 1 day and 1 month.
Min./max./avg. values recorded for eight parameters:
- every second for one minute for the 1-minute curve
- every minute for one hour for the 1-hour curve
- every hour for one day for the 1-day curve
- every day for one month for the 1-month curve
Forecasting (PM850 only) Forecasting of the values for the trended parameters
for the next four hours and next four days
