and
Entry into BG-Map Software on Palmtop
Prior to Physical Setup of the Total Station
1.
Organize all items found
on the “Checklist for Field Collecting” and bring
all items necessary to the field mapping location.

2.
Go out into the garden
and find the control point that will become the first site for data collection.
Be sure you also know the identification number of this control point.

3.
Visually locate and
determine the identification number of the second control point that will allow
you to orient the total station properly. The second control point must be
visible for proper total station set up.

Note: For
reference purposes throughout these instructions, the front of
the total station is the side facing the object to be measured and the back of
the total station is the side with the LCD display panel.

Tripod Setup
4.
Begin setting up the
yellow and orange tripod by spreading the legs and extending/contracting the
legs so that the height of the tripod will be suitable for observation when the
total station is placed on top of the tripod. (Note: Remember that the
collimator (crude siting device) on top of the total station is used regularly
during total station operation and must be low enough for easy use.)

Remove the orange
plastic protective cover from the tripod head by turning the red center screw
counter-clockwise on the underside of the tripod head.

Position the tripod
directly over the top of a control point, spreading the legs far enough to
insure stability. Make sure, by sighting downward through the center screw on
the tripod, that the tripod is centered over the control point. Position the
tripod shoes firmly on the ground, keeping in mind the need to remain over the
top of the control point and that the tripod should remain relatively level.

Mounting the Total Station
7.
With the tripod in
place, carefully remove the total station from its carrying case and place it
on the tripod head. Attach the total station to the tripod head loosely by
turning the red mounting screw clockwise.

8.
With the total station
still loosely attached to the tripod head, look through the eye piece on the
black optical plummet two-in-one knob located on the front side of the total
station (This eye piece provides a view with a center mark that allows you to
center the total station directly over the top of the control point). Rotate
the optical plummet eye piece knob (the smaller of the two-in-one knobs) until
the center mark can be seen clearly.

Now, slide the total
station around on top of the tripod while viewing the control point through the
eye piece of the optical plummet. Once the total station is centered over the
control point (with the center mark over the control point), tighten the red
tripod mounting screw so that the total station is firmly attached to the
tripod.(At least, have the center mark overlap some part of the control point.)

Leveling the Total Station
11.
With the tripod and
total station now centered over the top of the control point, adjust the tripod
legs by extending/contracting them, to position the bubble of the circular vial
located on the tribrach of the total station to the center. (DO NOT try to push
down on the tripod shoe with your foot to make these adjustments-this may
disturb the tripod location.)

12.
With the tripod now
level, release the black clamp screw (the smaller of a two-in-one knob located
on the back side of the total station to the right of the square red power
supply switch) by turning it counter-clockwise until the total station rotates
freely.

13.
Rotate the total station
until the back of the unit is aligned with two of the leveling screws located
on the bottom plate of the total station (Let’s call this POSITION
#1). Re-tighten the clamp screw. Look for the plate vial (or leveling
“bubble”) located just above the display panel on the back of the
total station. The plate vial will be used to make fine adjustments in
leveling.

14.
Begin leveling in POSITION
#1 by turning the two leveling screws in opposite directions until
the bubble on the plate vial moves to the center of the glass level. With POSITION
#1 leveled, loosen the clamp screw and rotate the total station
until it aligns with another set of leveling screws (Let’s call this POSITION
#2). Repeat the leveling procedure by turning the clamp screws in POSITION
#2 until the plate vial bubble is once again centered. Loosen the
clamp screw and rotate the total station back to POSITION #1 and
repeat the leveling procedure. This procedure should be repeated from POSITION
#1 to POSITION #2 until both positions
remain centered without further adjustments.

Upon completion of
leveling, the “bubble” of the circular vial (located on the tribrach
of the total station just above the leveling screws) should still remain in the
center. If not, return to step 11 and check the level again.

Powering Up the Total Station
16.
Turn on the total
station by pressing the red power supply switch (the red square button) once on
the back of the total station. After the machine beeps, the display panel will
display the message: “TURN SCOPE”. Loosen the black telescope clamp
screw (the smaller of a two-in-one knob located on the back of the total
station directly above the power supply switch) by turning the knob
counter-clockwise. Pivot the objective lens assembly vertically at least 90o until
the “TURN SCOPE” message disappears. Now, re-tighten the telescope
clamp screw and remove the lens cover protecting the objective lens.

Powering Up the Palmtop Computer
17.
With the total station
powered up, attach the palmtop computer to the mounting bracket on the tripod
and plug the 9-pin female cable into the palmtop. Plug the other end of the
cable (round slotted male connector) into the total station (The receptacle is
located on the front of the total station just above the optical plummet eye
piece).

21.
To begin setting the
Station Coordinates, press the “S” key. You will be prompted with:
“Coord? (#StationID)”. Enter the IDnumber (ie. 2975) of the control
point you have selected for your setup location preceded by the # sign; for
example #2975 (This is the location where the total station is currently
located). Press the “ENTER” key. Coordinates will appear next to the
Station X and Station Y labels at the top of the page.

Next, press the
“A” key to begin manually setting the horizontal angle. Enter the
Idnumber (ie. 2973) of the control point where the prism is set up preceded by
the # sign; for example #2973 (this is the other line-of-sight control point
that will tell the total station where it is located). Press the “ENTER”

23.
Write down or note the
Azimuth; for example 18o 02′ 50″. You will use this
information in Step #24 as you align the total station with the second control
point. DO NOT press the space bar on the palmtop as instructed. Press
“Q” to quit (the palmtop returns to the Setup Menu).

Now, return to the total
station and release the black clamp screw (the smaller of a two-in-one knob
located on the back side of the total station to the right of the square red
power supply switch). Rotate the total station until the display panel reads an
angle close to the Azimuth angle you wrote down in Step #23; in this example,
18o 02′ 50″. Tighten the clamp screw and turn the larger
tangent screw knob on the two-in-one knob to make the necessary fine
adjustment. Once you have the exact angle showing on the display panel, press
the “H.HOLD” button on the back of the total station below the
display panel TWICE. The angle has been locked into the total station memory.

Release the clamp screw
so the total station can rotate. (NOTE: the angle will not change as the total
station rotates.) Using the collimator (a crude sighting device) on the top of
the total station instrument, align the total station with the prism. Utilizing
the telescope tangent screw and the tangent screw, center the eyepiece lens
vertically and horizontally on the prism with the cross hairs centered on the
prism. Focus on the prism using the large focusing knob as necessary.
