Averaging times (Bimetal function)
For the most current and power values, a mean value is built. You can
program a common averaging time for the current measured values
L1, L2, L3 and N , and one for power measured values, real power,
apparent power and reactive power is programmable.
Presettings:
Averaging time of currents = 900 seconds
Averaging time power = 900 seconds
The following averaging times are selectable:
5, 10, 30, 60, 300, 480, 900 seconds
Method of taking the mean
The used exponential method reaches at least 95% of the measured
value after the set averaging time.

Programming of averaging times
Real power
In programming mode scroll to the averaging time of power with key
2. Confirm using key 1.
The averaging time flashes and can be changed by pressing key 2.
Confirming with key 1, the averaging time stops flashing. Using key
2 you can now change to programming menu „Averaging time for
current“.
Currents
In programming menu scroll to the averaging time for currents with
key 2. Confirm selection with key 1.
The averaging time is flashing and can be changed using key 2.
Confirming with key 1, the averaging time stops flashing. Using key
2 you can now change to programming menu „Rotation time“.
Averaging time= 5 seconds
Averaging time = 5 seconds
Mean value=real power
