Measuring errors are possible in case of:
Î colourless fluids (e.g. water)
Î clean, translucent glass
Î styrofoam or similar semi-translucent surfaces
Î strongly reflecting targets that deflect the
laserbeam
Î measurements aimed at moving objects
Causes:
Î Strongly reflecting targets deflect the laser
beam and cause measuring errors.
Î Non-reflecting, dark surfaces increase the
measuring time.
For constantly high-quality measurements
 Perform control measurements periodically.
 Perform control measurements before and
after important measurements.
8.2 Switching on/off
 Switch on the device by pressing key 4 briefly.
The device shows the battery symbol until ano-
ther key is pressed.
 Switch off the device by holding key 5 for
several seconds.
If no key is pressed for 180 seconds, the device
switches off automatically.
8.3 Clear key
 Undo the most recent action by pressing key 5
briefly.
8.4 Adjusting the measuring
plane
See drawing F:
Rear measuring plane is the standard setting.
 For measurement from front edge, press key 7
for several seconds.
 For measurement from rear edge, press key 7
for several seconds again.
8.5 Unit setting
Metric system is the standard setting.
 To change the unit, hold key 6 for several
seconds.
With every keypress, the device switches to the
next unit.
Possible units:
Î feet inch fractional
Î summary row up to 1/16 inch
Î second row up to 1/8 inch
Î inch fractional
Î summary row up to 1/16 inch
Î second row up to 1/8 inch
Î meters with mm display
9 Measuring
9.1 Measuring single distances
 Press key 4 briefly.
 Aim active laser at target area.
 Press key 4 briefly.
The device measures the distance.
The device displays the result immediately.
9.2 Continuous measuring
This function enables distances to be staked out.
 Hold key 4 for several seconds.
Continuous measuring starts.

row.
10 Functions
10.1 Add/Subtract
Add:
 Measure the first distance.
 Press key 6 once.
The device adds the second measuring result
to the first measuring result.
 Measure the second distance.
Subtract:
 Measure the first distance.
 Press key 6 twice.
The device subtracts the second measurement
result from the first measurement result.
 Measure the second distance.
Repeat if required. The device displays the result
in the summary row and the previous value in the
second row.
