Measurement functions
Value
Depending on the frequency of the measured
current: f ±2 Hz
n
±0.5% or ±0.002 × I
(at currents in the range of 0.01...4.00 × I
DFT: -50 dB at f = n × f
RMS: No suppression
Change
Menu changes
Phase current angle values added to Monitored
data view. Minimum demand value and time
added to recorded data. Logarithmic demand
calculation mode added and demand interval
setting moved under Measurement menu as
general setting to all demand calculations.
