from the instrument which is less
than 5° from the horizontal. Check
by activating the V-angle display.

3. Start calibration by pressing

and

simultaneously.

4. Measure V-angle with

.

or

back to measuring menu with

without modification.

5. Change telescope position and

aim on point again.

6. Again measure V-angle with

vertical index error is computed.

Keep actual value.
