and vertical brake hand-wheel and read the horizontal angle;
e.g. HA (R)=190°13′40″
4. If 2C=L-(R±180°)=-30″≥±20″, the instrument need to be
calibrated.
Calibration
1.Use the horizontal slow motion knob to adjust the
horizontal angle to the right reading which has eliminated the C.
R + C = 190°13 '40 "-15 "= 190°13' 25";
2.Take down the reticle bed cover between the telescope
eyepiece and focusing hand-wheel, adjust the calibration screw
of the crosshair on the left and right. First, loosen the screw on
one side, and screw up the screw on the other side, move the
reticle and focus on target A;
3. Repeat the test steps, calibrate it to | 2 C | < 10;
4. Tighten the calibration screws, put the protective cover
back.
