Threshold
: reference value in Ampere RMS where the record will start.
Hysteresis
: Percentage value of the tolerance for
the start according the selected threshold. If you want no tolerance, set the value to 0 %.
You can start the record after starting the motor: the next trigger will be the next overintensity if the evolution of current
is under the low threshold (threshold * hysteresis/100) and reaches the threshold.
10.11.2 In version 1.1 of the firmware or later
Stop of the inrush record if, after trigger, the current is higher than (threshold * hysteresis/100) and reaches the threshold.
10.11.2.1 Trigger according to a duration or a date
You can set up the record so that it starts after a selected period or at a specified date and select a stop condition (record
time or manual stop)
10.12 Recordable parameters
•
Number of observed values: you can select it under "Number of parameters". The possible values range from 1 to
14.
•
Selection of values: you can select:
10.12.1 Voltage and Current
•
Efficient RMS : efficient value o Fund fund : efficient value of the fundamental o Average dc : average value (DC
offset) o Peak cr : maximum value between the max and min peaks
•
Peak factor fcr : ratio between the peak value and the efficient value
(1,414 for a sinusoidal signal) - Total harmonic distortion THD: ratio of the total presence of harmonics to the fundamental
component of the signal
•
Distortion factor DF: DF% is the ratio of the total presence of harmonics to the true efficient value of the signal.
10.12.2 Power
•
P : Active o Q : Reactive o S : Apparent
•
Energy: cumulative value; you will find an initialization at page « Display »
10.12.3 Power Factor
•
F.P. : power factor
•
Cos phi : cosine between the fundamental components of the signals U1 and I1,
•
Frequency: the calculation of frequency is made at the input U1.
•
Standard data acquisition channel: you can select among the free channels.
For voltage, current and power, you can select each line (ex. U1, P2, I2) or the global value of the network (Ut, It, Pt)
For each parameter, you can change the following values:
