instrument detects two
phases
connected
together it displays the
screen to the right.

Two phases are connected
together.
THE PREVIOUS RESULTS CANNOT BE SAVED.
 In the
mode, if the
voltage of one or more
phase is too low, one or
more phases has a low
voltage the instrument
will
show a screen
similar to the along side
displayed.

Message “LOW Voltage
Phase T”: means that
Phase T has a low voltage
value. Similar message for
Phase R and S.
