Min/max measurements
The Energy trip unit calculates the real-time maximum and minimum values reached
since the last reset.
Certain values are time stamped.
All of these values take into account the positive and negative values.
For example, if the previous maximum value was 25 and a value of -30 is measured,
the new maximum value becomes -30.
