polarizing coils are energized from the
'incoming' frequency, while the radial
field coils are connected to the 'running'
circuit. If there is no difference
between the two circuits either in phase
angle or frequency, the pointer will
remain motionless at the 12 o'clock
position on the dial. With no frequency
difference, any phase angle difference
will cause the pointer to take up a
position away from the point. If,
however, there is a difference in
frequency, this phase relationship will
be constantly changing and the pointer
will consequently rotate continuously in
one direction or the other at a speed
corresponding to the difference in
frequency. If 'incoming' is at a higher
speed than the 'running', the pointer
rotates clockwise, and counterclockwise
if its speed is lower.
(3) When the lamps turn off together, the two
sources are synchronized. When the
'incoming' frequency has been adjusted
to equal that of the 'running' frequency,
the pointer will come to rest at a point on
the scale depending on the phase
displacement of the two voltages. The
