Don’t collimate the sun directly
Avoid insolating the instrument, and don’t collimate the sun directly for
protecting eyes and instrument.
Set up the instrument on the tripod
When using it please insure the connection between tripod and instrument is
firm. It is better to work with wooden tripod for the measurement accuracy.
Assemble the tribrach on the instrument
The setting of tribrach would influence the accuracy. The tribrach should be
check frequently, the screw which connects the tribrach and alidade must be
locked tightly. And the central fixing screw should be tight.
Avoiding the librations on the instrument
When transporting, keep the instrument in the case and try your best to
lighten librations.
Carry the instrument
When carrying，the instrument handle must be held tight.
High temperature condition
If put the instrument in high temperature condition for a long time, it is bad
for the instrument performance.
Temperature changing sharply
The sharp temperature changing on the instrument or prism will shorten the
distance measurement range, for example, after taking the instrument out
from a warm car to a cold condition, wait for some time, it can be used when
it adapts to the surrounding condition.
Check the battery power
Before using it, you should check the power whether it is enough.
Take out the battery
It is not suggested to take out the battery when the instrument is on,
otherwise, the stored data may be lost, so it is better to replace the battery
after power off the instrument.
Stored data responsibility
PENTAX should not be held liability for the lost data because of wrong
operation.
The noise from the instrument

4.5.6 Offset Measurement Mode
There are four kinds of Offset Measurement Modes:
Angle Offset Measurement
Distance Offset Measurement
Plane Offset Measurement
Column Offset Measurement
1) Angle Offset Measurement
This program is used to measure the point where it’s difficult to set prism.
Place the prism at the same horizontal distance from the instrument as that
of point A0 to measure.
●When measuring coordinate of ground point A1(projection of point A0),set
instrument height and prism height.
●When measuring coordinate of point A0,set instrument height only(Prism
height is set as 0).
●Under angle offset measurement mode,there are two methods to set
vertical angle:
1.Free vertical angle: vertical angle ranges from up-and-down movement of
telescope.
2.Lock vertical angle:vertical angle is locked and can’t range from
up-and-down movement of telescope.
Thus,if collimate A0 with the first method, vertical angle ranges from
up-and-down movement of telescope,and meantime slope distance(SD) and
63
elevation difference(VD) will change too.But if collimate A0 with the second
method,vertical angle is locked in the direction where prism is located and
can’t range from up-and-down movement of telescope.

1. Set the instrument on the tripod, and place a piece of
white paper with a cross drawn on it right under the
instrument.
2. Move the paper so that the intersecting point of the
cross comes to the centre of the laser mark.
3. Rotate the instrument around the vertical axis, and
observe the centre mark position against the
intersecting point of the cross at each 90° rotation.
4. If the laser mark always coincides with the
intersecting point, no adjustment is necessary.
76
2) Adjustment
When a centre part where a cross intersection and the laser mark look the
brightest shifts by 0.5mm or more (at the instrument height 1.5m), it is
necessary to adjust it.
A repair engineer does this adjustment. Please contact the LINERTEC dealer.
5.5 Vertical Cross-hair on Telescope
1) Check
(1) Set the instrument up the tripod and carefully level it.
(2) Set a point A front the instrument 50m apart;
(3) Collimate the point A and adjust the vertical tangent screw; If the point
appears to move continuously on the hair, adjustment is not required.
Otherwise, adjust it.
2) Adjustment
(1) Set the instrument, and set the point A front the instrument 50m apart.
(2) Take off cover of telescope eyepiece, there are 4 screws for the reticle
part.
(3) Loosen all four fixing screws slightly with the cross screw-drive.
(4)Revolve the eyepiece section so that the vertical cross-hair coincides to
point A, finally, re-tighten the four screws.
(5) Repeat the checking and adjusting until there is no deviation.
77
NOTE:
1）After the adjustment of cross-hair, please check the collimation error and
vertical index error.
2) Refer to the chapter “5.9 EDM Optical Axis and the Telescope Sighting
Axis Error” to check the axis. At last check the collimator error again.
78
5.6 Horizontal Collimation Error C
If the telescope’s sight line isn’t perpendicular to the horizontal axis, the
collimation error will appear. The assembling, transportation and operation
will cause this error.
If the collimation error isn’t over the permitted range, with the program the
instrument can correct this collimation error.
NOTE: After the program correction this deviation error is also on the
instrument.
1) Check
(1) Set-up the instrument on tripod or adjustment platform and leveling
accurately.
(2) Aim at the cross-hairs of collimator or the obvious target at a distance.
Get the face left angle reading H1 and the face right angle reading Hr.
(3) Calculating the horizontal collimation error C according to C= （ HlHr±180°）/2,if C<8″, no adjustment will be necessary. If C>8″, proceed with
the following adjustment.
2) Adjustment by program:
Set-up the instrument on tripod or adjustment platform, and leveling
accurately.
Procedures:
1. Power on, run the software “TS810Setup”, on the screen tap
or
keys
until Collimation displays, tap it to display collimation error and vertical
index error setting menu.
2. Aim at the cross-hair of collimator at telescope left, tap “Left value” to
read the horizntal and vertical angles.
3. Aim at the cross-hair of coillmator at telescope right, tap “Right value” to
read the horzontal and vertical angles.
79
4. The software will calculate the new collimation error and vertical index
error automatically.
5. Tap “Enter” to save the new values, or tap “Cancel” to use old values.
Note:
The adjustment can be performed by the program when C<30″, if C>30″,
adjust the reticle.
Reticle Adjusting:
1. Rotate the instrument in face right position, turning horizontal tangent
screw until Hr′=Hr+C.
2.Loosen the shield of telescope’s reticle.
3. Adjusting two screws at left and at right until the vertical hairs of
telescope’s reticle coincides with the cross-hairs of collimator or target.
4. Repeat the check and adjustment procedure until the error is accepted.
NOTE:
1. When adjust the screws of reticle, firstly loosen the screw on the moving
direction of reticle, secondly tighten another screw by the same mount,
clockwise turning is for tightening, and anticlockwise turning is for loosening,
the turning mount for tightening or loosening should be same.
2. After the reticle adjustment, it is necessary to adjust the vertical index
error by program.
5.7 Vertical Index Error
The deviation between vertical circle zero position and horizontal direction is
vertical index (i), it is necessary to concern this error when measure vertical
angle. The instrument program applied a formula to remove this error. This
correction can offer the index for the formula.
Warning: Before starting this operation, be sure to read manual carefully,
otherwise it may cause data faulty.
Because of the close relationship between vertical index and compensator
zero position, it is necessary to check and adjust compensator zero position
when adjust the vertical circle, the value should be stable when reading.
1) Check:
80
Please adjust the reticle of telescope and correct the collimation error before
this operation.
(1) Mount the instrument at the tripod or a stable device and level it
accurately, then turn on the instrument.
(2) Aim at the cross-hairs of collimator or the obvious target at a distance, VA
should be about ±10°. Read the face left angle Vl and face right angle Vr.
(3) Calculate the index error according to the formula below:
i = ( Vl+Vr-360°)/2
(4)If I<10〞, no adjustment is necessary , or you have to adjust it .
2) Adjustment by program:
Set-up the instrument on tripod or adjustment platform, and leveling
accurately.

(4) Enter EDM signal testing screen.
(5) Observe through eyepiece, turn the focusing knob until the red mark is
clear, if the deviation between mark and cross-hair is not over 1/5 of red mark
diameter, adjustment is unnecessary.
2）Checking (For W-1502N series)
(1) Install the instrument at the tripod or a stable device and level it
accurately, then power on the instrument.
(2) Set a reflective sheet about 5m-20m far away from the instrument.
(3) Aim at the sheet cross-mark with telescope reticle.
(4) Enter EDM signal testing screen.
(5) Observe the laser spot, if the laser spot coincides with the cross-mark of
reflective sheet, adjustment is unnecessary.
NOTE:

Appendix I: Atmospheric correction formula and
chart(Just for reference)
Factory setting:
temperature: 20℃, pressure:1013hpa, 0ppm
The correction:
Kpt＝274.417-0.2905*p/(1＋0.0036*t)
Where:
p--Pressure value (hPa)
t--Temperature value (℃)
Kpt--Atmospheric correction (ppm)
Example:
t=20℃, p=1013hpa, L0=1000m.
Then:
Kpt=0ppm
L=L0(1+Kpt)=1000×(1+0×10-6)=1000.000m
The atmospheric value is obtained easily with the atmospheric
correction chart. Find the measured temperature in horizontal axis,
and pressure in vertical axis on the chart.
Read the value from the diagonal line, which is the required
atmospheric correction value.

Appendix II: Correction for refraction and earth
curvature
Considering the correction of refraction and earth curvature for
distance measurement, the formula for slope distance, horizontal
distance and vertical distance applied in the instrument are as
followings:
The conversion formula for horizontal and vertical distance is as
follows when correction for refraction and earth curvature is not
applied:
HD=SD COS§
VD=SD ∣SIN§∣
NOTE:
The factory setting for the refraction coefficient K is 0.142.
Refer to the section 3.10 to change the value of K.
