General Handling Precautions
Before starting work or operation, be sure to check that the instrument is
functi onin g correctly w i th normal perf ormance.
Do not submerge the instrument into water.
The instrument can not be submerged underwater.
The instrument is designed based on the International S tanda rd IP66,
therefore it is protected from the normal rainfall.
Setting the instrument on a tripod
When mounti n g the i ns tru me nt on a tripod , use a wooden tri pod when po ssible. The vibr ations th at may occur when usi ng a metallic tripod can effect the
measuring precision.
Installing the tribrach
If the tribrach is installed incorrectly, the me asuring precisi on could be
effe cted . Occasionall y chec k the adjust ing scr ews on the tribrac h. Make sure
the base fix in g lever is locked and the base f ixin g screws are tightened.
Guarding the instrument against shocks
When transpor ting the instrument, provide some protection to minimize risk
of shocks. Heavy shocks may cause the measurement to be faulty.
Carrying the instrument
Always carry the instrum ent by its handgr ip.
Exposing the instrument to extreme heat.
Do not leave the instrument in extreme heat for longer than necessary.
It could adversely affect its performance.
Sudden changes of temperature
Any sud den chang e of temper atu re to the instrument or pris m may resu lt i n a
reduction of measuring distance range, i.e when taking the instrument out
from a heated vehicle. Let instrument acclimate itself to ambient temperature. When a high degree of precision is required for measurement, provide
shade against direct sunlight for the instrument and tripod.
Battery level check
Confirm bat t ery le vel re maining before opera t ing.
Store with the batteries removed, when operation is halted for more than a
month. Leav i ng the batteries att a che d for ext e nded period of time can res ult
in battery leakage, which may lead to malfunctioning.

3.6 Stadia Surveying
S
This instrument can be used for stadia surveying, Measurement by stadia is
a convenient method for measuring distances with the stadia hairs of the
instrument, in combination wi th a gradua ted rod, such a s a leveling rod o r
stadia rod, which is preferable fo r long distances. The distance from the center of the instrument to the rod is found by sighting through the i nstrument on
the rod and multiplying the stadia interval by 100. The stadia interval is the
distance between the to p stadi a hair r eading and the bott om stadia fai r read ing.
tadia hair s
d
D=100 × d
1
Set the rod on the point to be surveyed.
2
Sight through the telescope of the leveled instrument and determine
the distance or interval, “ d ”, between the top stadia hair reading
and bottom stadia hair reading of the rod.
3
The horizon tal distance “ D ” from the cen ter of the instrument to the
rod is equal to 100 times the stadia inte rv al, “ d ”.

8 CHECK AND ADJUSTMENT
● Pointers on the Adjustment
1
Adjust the eyepiece of the telescope properly prior to any checking
operation which involves sighting through the telescope.
Remember t o f ocus properly, with parallax completely eliminated.
2
Carry out the adjustments in the order of item numbers, as the
adjustm ent s a re dependent one upo n ano t her. Adjust men ts carried
out in the wrong sequence may e ven nu llify previous adjustment.
3
Always conclude adjustments by tightening the adjustment screws
securely (but do not tighten them more than necessary, as you may
strip the threads, twist off the screw or place undue stress on the
parts).
Furthermore, always tighten by revolving in the direction of
tightening tension.
4
The atta chm ent scr e ws mu st also be t ight e ned suffi ciently, upon
comple ti on of adjustment s .
5
Always repeat checking operations after adjustments are made, in
order to confirm results.
● Notes on the Tribrach
1
If any lev elin g screw becomes loose and slack or if collimation is
unstable due to the looseness of leveling screws, adjust by
tightening the adjusting screws (in 2 places) installed over each
leveling screw with a screwdriver
2
If there is an y slack between the l evelin g scr ews an d the base,
loosen the set s crew of t he hol ding ring and t ighten t he holdi ng ring

8.3 Adjustm ent of the Vertical Cross-hair
Adjustment is required if the vertical cross-hair is not in a place perpendicular to the ho riz ontal axis of t he te l escope ( si nce it mus t be possib le to use
any point on the hair for measuring horizontal angles or running lines).
● Checking
1
Set the instrument up the tripod and carefully level it.
2
Sight the cross-hairs on a well defined Point A at a distance of, at
least, 50 meters (160ft.) and clamp horizontal motion.
3
Next swing the telescope vertically using the ver tical tangent screw,
and check whether the point travels along the length of the vertical
cross-hair.
4
If the point appears to move continuously on the hair, the vertical
cr o ss-hair lies in a plane perpen dic ula r to the h o rizontal axi s ( and
adjustment is not required ).
5
However, if the point appears to be displaced from the vertical
cross-hair, as the telescope is swung vertically, then proceed with
the fol l ow i ng adjustment.
● Adjustment
1
Unscrew the cross-hair adjustment section cover, by revolving it in
the counterclockwise direction, and take it off. This will expose four
ey epiece section att achment screws.
2
Loosen a ll fou r attachment scre w s sli g htl y w it h th e accessory sc re wdrive (while taking note of the number of revolutions).
Then revolve the eyepiece section so that the vertical cross-hair
coincides to Point A’.
Finally, re-tighten the four screws by the amount that they were
loosened.
