Always conclude adjustments by tightening the adjustment screws securely but do not tighten them more than necessary as you may strip the threads twist off the screw or place undue stress on the parts Furthermore always tighten by revolving in the direction of tightening tension The attachment screws must also be tightened sufficiently upon completion of adjustments Always repeat checking operations after adjustments are made in order to confirm results Notes on the Tribrach Note that the angle measuring precision may be effected directly if the tribrach has not been installed firmly 1 2 If any leveling screw becomes loose and slack or if collimation is unstable due to the looseness of leveling screws adjust by tightening the adjusting screws in 2 places installed over each leveling Screw with a screwdriver If there is any slack between the leveling screws and the base loosen the set screw of the holding ring and tighten the holding ring with adjusting pin until it is properly adjusted Re tighten the set Screw on completing the adjustment Adjustment screw Leveling screw Holding ring Set screw 6 CHECK AND ADJUSTMENT 6 3 1 Checking Adjusting the Plate Level Adjustment is required if the axis of the plate level is not perpendicular to the vertical axis Check 1 Place the plate level parallel to a line running through the centers of two leveling screws say A and B Use these two leveling screw
