There are three different length tic marks on the altitude scale. The longest tic marks
represent 10-degree increments, the medium marks represent 5-degree increments and
the short marks occur at one degree increments. The lowest setting is 15 degrees altitude,
so that first long tic mark represents 20 degrees.
In the middle of the latitude range (approximately 36 degrees), one full turn of the altitude
positioning-device equals one degree, with slightly different amounts at the extremes.
Each tic (or high spot) on the altitude-positioning device knob is equal to two arcminutes
(see Figure 26 for the definition of a tic on this knob).

Tip
Remember the "Right Hand" Rule!
The Paramount ME uses "right-handed" threads. If you need to make an altitude
adjustment, and forget which direction to rotate the altitude-positioning device,
just use the right hand rule.
For example, suppose you need to increase the mount's altitude. Point the
thumb on your right hand upward. Rotate the altitude-positioning device in the
direction your fingers curl. Simple!
Initially, consider adjusting the altitude slightly higher than your latitude so that any
adjustment during polar alignment is downward. If the altitude must be adjusted higher,
you can lift the declination housing, or counterweight shaft (page
