5.4.8. Inrush current (only PQA82x)
This option permits to set the control parameters relative to recording of inrush current
events (see § 10.3) which is completely independent from periodic analysis (regulated by
integration period). The below screen is shown by meter:

Press F4 key (alternatively touch MODIFY at display) to set the below parameters for
recording of inrush currents:
The value of current threshold which is correspondent to detection and recording of
inrush current event from meter. This value cannot exceeded the full scale which is
selected for the clamp type used for current measurements (see § 5.3.1.3).
The value of the inrush current detection time interval expressed in seconds. Possible
values which can be set are 1s, 2s, 3s and 4s.
The detection type of inrush currents events. The fix mode (the event is detected
whenever the input current value is over the set threshold) or var mode (the event is
detected if the difference between two instantaneous values in a half period exceed the
set threshold) are possible.

1. Move the cursor using arrows keys on field relative to “Inrush current” , marked it with
blue background.
2. Use up or down arrow keys or press F3 or F4 keys (alternatively touch the MOD(+) or
MOD(-) s at display) to set the correspondent value. Pressing and holding these keys
permits a rapid values setting, while the single pressure increases or decreases the
value by one single unit. Use left or right arrow keys to move on various fields.
3. Press SAVE or ENTER keys (or the smart icon
) to save each performed setting.
