5. Self-check and Cali ration
The instrument must be se f-checked after service for a certain time or before operation in a major project. If the
accuracy is found beyond to erance, user makes some adjustment according to methods as fo ows.
5.1 Accuracy check
X、Y accuracy check
(1) Set a p atform in a room which is 20m far way from the wa , put the instrument on the p atform, and take the X axis
face to the wa .
(2) Power on and after the instrument is auto- eve ed, mark the aser ine which is on the wa as sign A, and make a
vertica ine a ong sign A
(3) Rotate the instrument by 90 degrees in turn, after the instrument is auto eve ing, mark the point of intersection of the
aser ine and the vertica ine as point B, C and D separate y.
(4) Measure the maxima distance h between two points which among point A, B, C, D.
(5) If h≤3mm, the accuracy is OK; If 3mm< h≤20mm, the accuracy is beyond to erance, the user cou d adjust and
ca ibrate the accuracy; If h>20mm, the accuracy is beyond to erance, user must contact with se er for service
Z axis accuracy check
（1）Fo ow X, Y accuracy check figure, measure the height H from horizonta aser p ane to the p atform when p acing
the instrument horizonta y.
（2）P ace the instrument vertica y on the p atform, and take Z axis face to the wa .
（3）Power on the instrument, make the peak to project on the wa , after the instrument is eve ing, mark E.
（4）When p acing the instrument transverse y, measure H2 from the aser dot to the p atform, ca cu ate H va ue
H 1

H1

（H=H1-H2+h/2）,and mark O’the highest dot among A, B, C and D. to measure H va ue, it is the reference dot of
p acing the instrument transverse y.
（5）Measure h’ from E to O’, if h＇≤6mm, the instrument accuracy is qua ified. If 6mm＜h＇≤30mm, the instrument
accuracy is out of to erance, if h＇＞30mm, the instrument accuracy is out of to erance, p ease contact the distributor.
5.2 Accuracy cali ration
According to the accuracy check resu t, mark O at h/2(the distance of highest and owest dot among A. B , C and D)..
(1) enter into ca ibration status
a power off the instrument, face X axis to the wa
b. press on/off key and TILT mode key at the same time, and then re ease on/off key and continue ho d TILT mode key,
after X.Y LEDS f ash three times, re ease TILT mode key, the instrument wi enter ca ibration status, and continue
rotating.
（2）X axis direction
a. Press se f-ca ibration direction on remote contro , the X ca ibration LED f ash on the instrument keypad, the
instrument wi enter X direction ca ibration.
b. Press the se f-ca ibration adjustment key on remote contro , move the aser ine up and down, unti it coincide with dot
O.
（3）Y axis direction ca ibration
a. Under ca ibration status, turn the instrument by 90 degree, make Y axis face to the wa .
b. Press se f-ca ibration direction se ect key on remote contro , Y ca ibration LED on instrument keypad f ash, the
instrument wi enter into Y direction ca ibration.
c. Press se f-ca ibration adjustment on remote contro , the aser ine move up and down, unti it coincides with dot O.
（4）Ca ibration confirmation
When X direction and Y direction confirmation are finished, press se f-ca ibration confirmation key, ca ibration LED is off,
ca ibration va ue is saved, the instrument exit ca ibration status.
（5）Z axis direction ca ibration
a. P ace the instrument vertica y
b. Press ON/OFF key and TILT mode key simu taneous y, and then re ease ON/OFF key and continue ho ding TILT
mode key, unti X,Y two LEDs f ash three times, and then re ease TILT mode key, the instrument enter Z axis ca ibration
status, rotate continuous y, Y direction LED f ash.
c. Press se f-ca ibration adjustment key on remote contro , the aser dot move up and down, unti it coincide with dot
O’.
（6） Ca ibration confirmation
When Z direction ca ibration is finished, press se f-ca ibration confirmation key, ca ibration LED is off, the ca ibration
va ue is saved, the instrument exit ca ibration status.
Note: after ca ibration is finished, it is necessary to power off instrument, after power on it again, the ca ibration is va id
fina y.
X axis is ca ibrated, it is necessary to make Y axis accuracy check, after Y axis id ca ibrated, it is necessary to make X
axis accuracy test, unti X and Y accuracy conform to requirement, then the instrument ca ibration is finished.
