5.2.2. CAPTURE PARAMETERS
To display the characteristics of the capture, press
Display in PEAK mode (see §5.2.4).
Display in RMS mode (see §5.2.3).
If a capture duration is displayed in red, it has been cut short due to one of the following:
■
power supply problem (battery low)
■
memory is full
■
measurement error
■
incompatibility between the quantity monitored and the configuration of the instrument (for example removal
sensor)
Choose the type of display, RMS or PEAK, by pressing the yellow button corresponding to the icon. The instrument then displays
the graphs.
NOTE: The PEAK button is not displayed when the inrush current capture recording mode is RMS only.
5.2.3. TRUE RMS CURRENT AND VOLTAGE
The RMS mode displays the record of the trend of the true half-cycle RMS current and voltage and the frequency trend graph.
The display depends on the type of selection filter:
3V: displays the 3 voltages during the inrush current capture for set-ups with neutral.
3U: displays the 3 voltages during the inrush current capture for set-ups without neutral.
3A: displays the 3 currents during the inrush current capture.
L1, L2, L3: display the current and voltage in phases 1, 2 and 3 respectively (for set-ups with neutral only).
Hz: displays the evolution of the network frequency vs. time.
Below are three examples of display.

button to move the cursor.
t: relative time position of the cursor
(t=0 corresponds to the start of the
inrush current capture).

Reminder of number assigned to the
graph displayed. In this example,
circle 1 is filled in, indicating that
channel A1 triggered the inrush
current capture.
A1, A2, A3: RMS values of currents 1,
2, and 3 in the half-cycle at the
position of the cursor.
