In "
" mode, if one of
the Phase-Phase
voltages does not reach
the minimum threshold
value of 100V, the
instrument does not
perform any test and
displays the following
screen.
Check that all phases of
the electric system
being tested have
voltage.

FRQ =50.0HZ V1-2=391V
V2-3= 0 V V3-1= 0V
LOW VOLTAGE L3
PHASE ROTATION
Phase "L3" does not reach
the minimum voltage value
FUNC
Using the "
" mode, if
two phases of the
electric system coincide,
the instrument does not
perform any test and
displays the following
screen.
Check that all phases of
the electric system
being tested have
voltage.

FRQ =50.0HZ V1-2=407V
V2-3= 0 V V3-1=407V
PHASE DOUBLED
PHASE ROTATION
Two phases of the three-
phase system being tested
are connected to each
other
FUNC
Using mode "
", if
phase sequence is
incorrect, the symbol
"132" is displayed.
Exchange two phases of
the electric system being
tested and repeat the
test.

This symbol DOES NOT
indicate that input B1 is
connected to phase L1,
input B2 is connected to
phase L3, input B3 is
connected to Phase L2. It
ONLY indicates that the
detected phase sequence
is incorrect

INCORRECT
PHASE ROTATION
