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.

 High temperature condition

Don’t put the instrument in high temperature condition（50℃ up）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 the surrounding
condition.

 The noise from the instrument

When the instrument working, it is normal if you hear the noise from instrument
motor, it will not affect the instrument work.

2. Preparation before Measurement

2.1 About Battery

2.1.1 Battery Power Symbol

Measurement is possible

The battery is lower, it is better to replace or recharge it

Measurement is impossible, it is necessary to replace or recharge

NOTE:

 The working time of battery will be effected by many factors, such as ambient

temperature, recharging time, recharging and discharging times. On the data safe side,

we suggest the users recharge the battery full or prepare several full batteries before

operation.

◆ The battery symbol only indicates power capability for current measurement mode.

The power consumption in distance measurement mode is more than in angle mode,

if the instrument enters into distance measurement mode from angle mode, the power

maybe auto-off because of lower battery.

◆ The symbol only indicates the supply power but not the instantaneous power change.

And if the measurement mode changes, the symbol will not show the power’s

decrease or increase immediately.

9. Offset Measurement

Offset measurement are performed in order to find a point where a target cannot be

installed directly or to find the distance and angle to a point which cannot be sighted.

It is possible to find the distance and angle to a point you wish to measure（target Point）

by installing the target at a location（offset point）a little distance from the target point

and measuring the distance and angle from the surveying point to the offset point.

The target point could be found in the following four ways.

9.1 Distance Offset Measurement

Sometimes we need to measure a coordinate of a point such as A1 whose position

cannot place a prism. assum that we know the horizontal distance from prism to A1. the

Distance offset measurement can be used.

12.3 Precautions When Performing Intersection

In some cases it is impossible to calculate the coordinates of occupied point if the

unknown point and three or more known points are arranged on the edge of a single

circle. It is also impossible to calculate if the included angle between the known points

is too small. It is difficult to imagine that the longer the distance between the instrument

occupied and known points, the narrower the included angle between the known points.

Be careful for the points can easily be aligned on the edge of a single circle.

An arrangement such as shown below is desirable.

It is sometimes impossible to perform a correct calculation such as shown below.

When they are on the edge of a single circle, take one of the following methods:

(1)Move the instruction station as close as

possible to the center of the triangle

.

(2)Measure one more known point which is not

on the circle.

(3)Perform a distance measurement on at least

one of the three points.

13. Point Projection

Point projection is used for projecting a point to an established baseline. By measuring a

point, its offset to start point, the horizontal distance and vertical distance between the

point and baseline can be calculated. the figure is shown as follow.

15.2 Defining the Vertical Curve of Roadway

The speciality of the roadway slope should be described by the vertial curve, there are three

attributes on the vertical curve—mileage, altitude and length, the mileage is representative

of the point where the slope is changed, the altitude is the altitude of the point where the

slope is changed ,the length indicate how much curve length is disigned to implement the

slope changing. the figure is shown as follow.

Mileage 0 508,306 1000,48
Altitude 324,325 329,247 325,689
Length 0 84,56 52,806

The input method of defining vertical curve is just same as the horizontal I.P., see

【Procedure of defining Horizontal point of intersection】

15.3 Roadway setout

When you select road-setout function ,a menu named “road setout” is poped up. before

16. Fileman

The instrument use a FAT16 file system to manage the data, all data obtained form

measuring can save to current measurement file. the extension name of measurement

file is *.MEA. all coordinates used by measurement can be picked up from current

coordinate file, the extentsion name of current coordinate file is *.COO.sometimes you

need to note an attribute of a point when you measure, the code file maybe a good helper,

the extension name of code file is *.COD. the extension of LINE-TYPE file for roadway

is *.LSH and *.LSV, *.LSV is vertical defining file for roadway, it always is loaded

after the *.LSH.

File operation is shown as follow.

1. The file operation dialog box is shown as the

picture of the left.

2.Press F1:【New】to create a new file. the type of

file can be changed by pressing F4:【Type】,after

you input the filename the file will be created.

3. Press F2:【DEL】to delete a file for the instrument.

deleting operation is dangerous ,for safty, you

should export the data first.

4. Press F3:【Read】to browse the highlight file. if

the file is coordinate file or measurement file then

stop bit.after you select filename you can press F4:

【Import】to perform the convection.

6. Measurement file can be exported from the

RS232,the operation is same as the【Importing】

7. Sometimes, many files have been saved in the

instrument, it will take a long time to delete these

files one by one.formating the disk would be a

good idea, when you format the disk, the prompt as

the picture on the left will appear. so you must save

all measurement data before you format.

8. Sometimes, you wish to view the fress space of

the disk, you can select the menu item 5 to do it.

9. Sometime, you need to previously input some

coodinates for the subsequent using. then you can
