Time
Recorded values
The event logging function allows the user to record the time during which a measured
value exceeds a threshold and its maximum value for the following parameters : Vrms
[V], Irms [A], P [kW], Q [kvar], S [kVA], THDV [%], THDI [%], missing Q [kvar], frequency*
[Hz], T1* [°C or °F] to T8* [°C or °F].
* Minimum values and duration below a threshold are also recorded for the frequency
and the temperatures.
