After the above steps, turn the theodolite to the circle right to
figure out whether the F value is within ±60. If yes, press FUNC
twice to complete the adjustment. As it shown in figure, the
coefficient of compensator is 3.97 and the temperature
coefficient of compensator value is 0.2 which expresses that it is
not necessary to be adjusted.
If the F value is over ±60, we have to calculate and reset
coefficient of compensator. As shown in the figure, F value is
175 which are over ±60.
Return the theodolite to circle left and aim at horizontal
collimator. As shown in the figure, aim crosshairs at a certain
graduation in vertical collimator, note down the corresponding
grid value. Then tighten the vertical clamp.
Observe the horizontal crosshairs of the theodolite, then adjust the leveling
hand wheel C to make the instrument go up 5 grids on the reticle, note down
the F value (F1). As shown in the figure, F1 is 627.
