Identifying Phases
The Read tab allows readings to be taken. On the left are displayed the phase
labels according to selected Phase Preferences. The phase labels are always dis-
played in order of time sequence with the label for 0
°
first. The right half of the
screen shows the most recent record in the list.
Phase Labels
When a signal is received from the Hotstick Unit, the timing information is com-
pared with the Reference Unit and a phase angle is calculated. If the phase
angle is within the configured Degree Tolerance (default 25
°
) of a configured
Phase Angle, the phase is identified on the display. After a stable measurement
is obtained (default is 3 consecutive readings within 5
°),
a new Record is saved.
The degree tolerance and parameters for determining a stable reading can be
changed using the PhaseTrakker Utility.
When a phase is identified, the measured phase angle is displayed next to the
label of the phase identified and an audible signal is given: Top position with
1 beep for the 1
st
Phase in time sequence, middle position with 2 beeps for the
2
nd
Phase, and bottom position with 3 beeps for 3
rd
Phase.
