Adding Pointer Adjustments
Periodic bursts of 3 adjustments, all of the same polarity which is selectable.
The interval between bursts is fixed at approximately 30 seconds. The interval
between adjustments within a burst is set to the minimum (see Note 2 page
50).
Phase transient pointer adjustment burst test sequence. All adjustments are of
the same polarity, which is selectable. The interval between bursts is fixed at
30 seconds. Each burst consists of 7 pointer movement. The first 3 in each
burst are 0.25 s apart, and the interval between the 3 and 4 movement, and
each remaining movement 0.5 seconds.
An 87-3 pattern is selected. The sequence pattern is 87 pointer movements
followed by 3 missing pointer movements. Pointer polarity is selectable and
the time interval between pointer adjustments settable (see Note 1 page 50).
An 87-3 pattern is selected. The sequence pattern is 87 pointer movements
followed by 3 missing pointer movements with an added pointer movement
after the 43rd pointer. The spacing between the added adjustment and the
previous adjustment is set to the minimum, (see Note 2 page 50). Pointer
polarity is selectable. The time interval between pointer adjustments can be set
(see Note 1). Added adjustments occur every 30 seconds or every repeat of the
87-3 pattern, whichever is longer.
An 87-3 pattern is selected. The sequence pattern is 87 pointer movements
followed by 3 missing pointer movements with a cancelled pointer movement

every 30 seconds or every repeat of the 87-3 pattern, whichever is longer.
Provides a continuous sequence of pointer adjustments. The polarity of the
