5.1.2.1 PROGRAMMING A CAPTURE

To program the capture of an Inrush current, proceed as follows:
■ At the Waveform Capture screen (Figure 5-1), select Inrush Current. The Capture Schedule screen is displayed.

2 Rapid programming and start of capture.
3 Shortcut to the Configuration menu to set triggering thresholds.
When triggering filter appears in red it is not available due to incompatibility with the configuration (connection, type of sensors, or

5 Displays the parameters of the capture.
6 Programs the capture.

7
: deletes a capture (this icon is displayed if a capture has been made).
To quickly start recording, press the
hysteresis of 100%. Note that the rapid starting of an inrush current modifies the configuration of the current threshold.
To program a capture, enter the triggering filter (3A, A1, A2, or A3), the start date and time, and the recording mode (RMS
+ PEAK or RMS only).
● The RMS + PEAK recording mode is used to produce a trend recording of the half-period RMS values and a
trend recording of the samples (envelopes and waveforms). The maximum duration of such a recording depends
on the network frequency; on average the duration is approximately one minute.
● In the RMS only recording mode, the recording of the samples is eliminated in favor of a longer maximum capture
duration. This mode records only the half-period RMS values and its maximum duration is about ten minutes.
