】

 

1.

Aim at the target. Press F2:

【

MEAS

】

at P1 in the 

measure mode. 
Press F1:

【

According to the application, you can select one 

of “single” ”repeat” ”continue” ”track 
”to measure distance 
Press

【

:

【

Mode

】

,pop up a little window for your 

selection 
3.Press

】

to finish measurement. The “ SD ” , ” 

HD ”, and ” VD ” will display as shown left. “# 
“indicate “no prism” or “reflector board” mode “*” 
indicate “prism” mode 

 
NOTE: 

 

Make sure that the target setting in the instrument matches the type of target used. 

 

If the objective lens is dirty, it will affect the accurate of measured results. Dust it off 
with your special brush and wipe it with your special cloth

（

in your carrring

）

casebefore putting away. 

 

If an object with a high reflective factor

（

metal, white surface

）

exists between the 

instrument and the target when measuring, the accuracy of the measured results will 
be affected. 

 

An angle is also able to be measured when distance measurement. 

 

# or * means measuring distance, at end of ”single”, ”repeat” mode measuring ,the 
symbol will disappear automatically. you can press

finish measurement then 

the symbol also disappear.
