tighten the vertical brake handwheel, the instrument display the
current telescope vertical Angle.

Slowly rotate feet X to 10 mm around in one direction, the
display of the vertical Angle will change from changing until
disappear to appear "compensation beyond!" correspondingly , it
indicate that the dip Angle of the verticalaxis is bigger than 3 ',
beyond the range of vertical plate compensator design . When
rotating the feet spiral recovery in the opposite direction ,
instruments shows vertical Angle again, if you can see the
change when testing it again and again in critical positions, it
says that vertical plate compensator works normally.
