118     Spectra Precision Focus 4 Total Station User Guide
Adjusting the electronic level
To adjust the electronic level, Zero point errors of vertical scale and horizontal angle 
corrections are used. See page 119. 
Checking and adjusting the circular level
Once you have checked and adjusted the 
electronic level, check the circular level.
If the bubble is not in the center of the level, use 
the adjusting pin to rotate the three adjustment 
screws of either circular level on the instrument 
main body or tribrach until the bubble is centered.
Checking and adjusting the optical/laser plummet
The optical axis of the plummet must be aligned with the vertical axis of the 
instrument.
To check and adjust the optical/laser plummet:
1. Place the instrument on the tripod. You do not have to level the instrument.
2. Place a thick sheet of paper marked with an 
X on the ground below the instrument.
3. Do the following:
–Look through the optical plummet 
and then adjust the leveling screws 
until the image of the X is in the center 
of the reticle mark .
–For the laser plummet, adjust the laser 
pointer to the X.
4. Rotate the alidade by 180°. 
–If the marked image is in the same 
position in the center of the reticle 
mark, no adjustment is required.
–For the laser plummet, if the laser 
pointer is on the X, no adjustment is 
required.

5. If the image or laser pointer is not in the 
same position, adjust the optical or laser 
plummet:
a. Use the supplied hexagonal wrench to 
turn the adjustment screws until the 
image of the X is in Position P. Position 
P is the center point of the line 
connecting the X and the center of the 
reticle mark  .
b. Repeat from Step 2. For laser plummet adjustment, you must remove a cap.
Zero point errors of vertical scale and horizontal angle 
corrections
Checking the calibration
1. Set up the instrument on the tripod.
2. Follow the leveling procedures described in Leveling the instrument, page 31.
3. Flip the telescope to the Face-1 position. The display and tangent screws are 
facing towards you.
4. Sight a target that is within 45° of the horizontal plane.
5. Read the vertical angle from the VA1 field in the Basic Measurement Screen 
(BMS).
6. Rotate the instrument 180° and flip the telescope to the Face-2 position. The 
display and tangent screws are turned away from you.
7. Read the vertical angle from the VA2 field.
8. Add the two vertical angles together, VA1 + VA2.
–No adjustment is required if the zero reference for vertical angles (VA zero 
setting) is set to Zenith, and VA1 + VA2 equals 360°. 
–No adjustment is required if the zero reference for vertical angles (VA zero 
setting) is set to Horizon, and VA1 + VA2 is either 180° or 540°.
–An adjustment is required if VA1 + VA2 is not one of the values listed above.
Note – The difference between the vertical angle reading the relevant angle (either 360° for 
Zenith, or 180° or 540° for Horizon) is called the altitude constant.

Adjusting the calibration
1. Press [MENU] and [7]. The calibration screen 
appears.
2. The Focus 4 total station has two-axis level 
compensation. Take an F1 measurement to a 
target on the horizon. Press [ENT].
The calibration fields for F1 are: 
The vertical angle is shown in the V0 dir= Horiz setting.
When you have taken the measurement, the 
message on the bottom line changes from DO 
NOT TOUCH! to Turn to F2.
3. Take an F2 measurement to the same target. 
Press [ENT].
The calibration values for F2 are: 
When the observation on F2 is completed, four 
parameters are displayed.
4. Do one of the following:
–To return to the first observation screen, 
press [ESC] or select the Redo softkey. 
–To set parameters on the instrument, press 
[ENT] or select the OK softkey.

The instrument constant
The instrument constant is a numerical value used to automatically correct for the 
displacement between the mechanical and electrical centers when measuring 
distances. The instrument constant is set at the factory. However, to ensure the highest 
operational accuracy, we recommend that you check the instrument constant several 
times a year.
The following figure shows the setup to check the instrument constant.
To check the instrument constant:
1. Set up the instrument at Point P, in as flat an area as possible.
2. Set up a reflector prism at Point Q, 100 m away from Point P. Make sure that you 
take the prism constant into account.
3. Measure the distance between Point P and Point Q (PQ).
4. Install a reflector prism on the tripod at Point P.
5. Set up another tripod at Point R, on the line between Point P and Point Q.
6. Transfer the Focus 4 total station to the tripod at Point R.
7. Measure the distance from Point R to Point P (RP), and the distance from Point 
R to Point Q (RQ).
8. Calculate the difference between the value of PQ and the value of RP + RQ.
9. Move the Focus 4 total station to other points on the line between Point P and 
Point Q.
10. Repeat Step 5 through Step 9 several times (about ten times).
11. Calculate the average of all the differences. The error range is within 3 mm. If the 
error is out of range, contact your dealer.

Checking the laser pointer
The Focus 4 total station uses a red laser beam to a laser pointer. The laser pointer is 
coaxial with the line of sight of the telescope. If the instrument is well adjusted, the red 
laser pointer coincides with the line of sight. External influences such as shock or large 
temperature fluctuations can displace the red laser pointer relative to the line of sight.

CCAUTION – The Focus 4 total station has different pin assignments from other Spectra 
Precision total stations.
To connect to an external power source, supply power to Pin 4 (power terminal) and 
Pin 5 (ground terminal) on the instrument. The instrument will use the external power 
source even if the internal battery packs is attached.
CCAUTION – Make sure that the power supplied is within the rated input range (4.5 V to 
5.2 V, 1 A maximum). Power supplied outside this range will damage the instrument.
To communicate with an external device, connect the RS-232C signal from the 
external device to Pin 1 (input terminal) and to Pin 2 (output terminal) on the Focus 4.
Cap the data output/external power input connector securely when the Focus 4 is not 
in use. The instrument is not watertight if the cap is detached or not attached securely, 
or when the data output/external power input connector is in use.
The Focus 4 can be damaged by static electricity from the human body discharged 
through the data output/external power input connector. Before handling the 
instrument, touch any other conductive material once to remove static electricity.
