35. CHECKS AND ADJUSTMENTS
With this option you can measure collimation error in your instrument so that the instrument can correct
subsequent single face observations. To measure the error, make angular observations using both faces.
• Perform adjustment in weak sunlight and no scintillation.
PROCEDURE Adjusting
1. Carefully level the instrument.
2. Install a target at a point about 100 m in the horizontal
direction from the instrument.
3. Select “Instr.const” in the Config. mode screen and select
“Collimation”.
4. While the telescope is in Face 1, sight the center of the
target correctly and press
[OK]
.
5. Wait untill a beep sound and rotate the instrument 180° .
Sight the center of the target correctly in Face 2 and press
[OK]
.
6. Press
[YES]
to set the constant.
• Press
[NO]
to discard the data and return to the screen in
step 4.
PROCEDURE Check 1: Perpendicularity of the reticle to the horizontal axis
1. Carefully level the instrument.
2. Align a clearly visible target (the edge of a roof for example)
on point A of the reticle line.
3. Use the telescope fine motion screw to align the target to
point B on a vertical line.
If the target moves parallel to the vertical line, adjustment is
unnecessary. If its movement deviates from the vertical line,
have our service representative adjust it.
