Levelling in Total Station

The document provides instructions for leveling a total station in 5 steps: 1. Setup the tripod with evenly spaced legs that are level. 2. Mount the total station on the tripod and secure it while inserting the battery. 3. Use the instrument's plummet to center it directly over the survey point by adjusting the tripod legs. 4. Roughly level the instrument using the circular level and adjusting the tripod leg heights. 5. Finely level and plumb the instrument using its electronic level and footscrews to display checkmarks, precisely centering it over the survey point.

LEVELING THE TOTAL STATION

 Leveling the Total Station must be accomplished to sufficient accuracy otherwise the

instrument will not report results.

 Leveling the instrument takes 30 to 45 minutes and make sure you can see all targets

from the instrument station before going through the process

Step 1: Tripod Setup

 Tripod legs should be equally spaced

 Tripod head should be approximately

level

 Head should be directly over survey

point

Step 2: Mount Instrument on Tripod

 Place Instrument on Tripod

 Secure with centering screw while

bracing the instrument with the other

hand

 Insert battery in instrument before

levelling

Step 3: Plumb

 Turn on the instrument. The laser plummet will be activated automatically, and the

Level/Plummet screen appears.

 IF NECESSARY Move the position of the tripod legs to make large

adjustments to center the plummet over the ground point.


 Use the footscrews to make small adjustments to center the plummet over the ground

point.

Step 4: Rough Leveling

 Adjust the height of the tripod legs to level the circular level bubble. Note: Do not move

the legs from their position just lengthen or shorten them, one at a time, as necessary to

bring the bubble into centre.

Step 5:Fine Plumb & Level:

 At this time your instrument should be very close to level and very close to the ground

point, check the plummet & circular level bubble to verify this. If this is not the case you

must repeat the Plumb & Rough Leveling steps above, otherwise, continue on to the next

step.

 Turn the instrument until it is parallel to two footscrews.

 Centre the electronic level of the first axis by turning the two footscrews. Arrows show

the direction of rotation required. When the electronic level is cantered the arrows are

replaced by checkmarks.

 Centre the electronic level for the second axis by turning the last footscrew. An arrow

shows the direction of rotation required. When the electronic level is cantered the arrow

is replaced by a checkmark.

 When the electronic level is cantered and three checkmarks are shown, the instrument has

been perfectly leveled up.


 IF REQUIRED, Centre the instrument precisely over the ground point. Loosen the

instrument from the tripod (loosen only) and slide the instrument over the point while

sighting.
