33. CHECKS AND ADJUSTMENTS
4.
While the telescope is in face 2,
sight the center of the target and
read out the horizontal angle A2
and the vertical angle B2.
Example:Horizontal angle A2=198° 34' 20"
Vertical angle B2=269° 30' 00"
5.
Do the calculations:
A2-A1 and B2+B1
If A2-A1 is within 180°±20
″
and
B2(B1 is within 360°±40
″
, adjust
ment is unnecessary.
Example:A2-A1 (Horizontal angle)
=198° 34' 20"- 18° 34' 00"
=180° 00' 20"
B2-B1 (Vertical angle)
=269° 30' 00" + 90° 30' 20"
=360° 00' 20"
If the difference is large even after
repeating the check 2 or 3 times,
make sure that checking and
adjusting of "33.2 Tilt Sensor" and
"33.3 Collimation" are completed.
If the results remain the same,
have our service representative
perform the adjustment.
