The stages involved in using a total station in surveying are as follows:
1. Setup the Tripod
2. Setting Up The Total Station On A Tripod
3. Adjusting the Total Station Level
4. Electronically verifying the levelling
5. Image Adjustment & Cross-Hair Focusing
6. Taking Measurements
Setup the Tripod
The tripod legs are secured in place so that they are evenly 
spaced. The tripod stand head should be level as well (roughly). 
The standing head should be in such a position that the top of 
the mount is exactly over the station mark.
Setting Up The Total Station On 
A Tripod
The Total station is then put on the stand after it has been 
secured to a particular spot. The instrument should be 
supported over the stand with one hand while the centring 
screw should be tightened with the other.
Adjusting the Total Station Level
The levelling foot screws are then adjusted to the point where the 
review point on the optical drive is midway. The tripod legs are also 
adjusted such that the bubble is in the middle. 
First, the air bubble is aligned with the two-foot screws and brought to 
the centre by rotating both screws in the same direction.
The air bubble is then adjusted corresponding to the extra foot screw 
and brought to the middle by rotating the screw from that point 
forward.
Electronically verifying the 
levelling
To begin, press and hold the "ON" button on the keypad until the 
instrument turns on. When the instrument is turned on, it emits a blare.
The function is selected once the screen has been displayed. The foot level 
screws are then replaced, allowing the electronic bubble to be focussed as 
well. The instrument is pivoted at 90 degrees again, and the cycle begins 
again.
Image Adjustment & Cross-Hair 
Focusing
After that, the horizontal and vertical cinches are removed, and the 
telescope is oriented at any featureless light foundation. The cross-hair 
is then adjusted until the image appears to be perfectly focused.
The telescope is then centred on the objective, and the centre ring is 
adjusted until the objective is sharply focused. The evacuation of 
parallax is then ensured by progressively moving the head to the side.
Taking Measurements
The entire station can be used to take measurements or observations 
once the preceding procedures have been performed.
