5. Measuring procedures in each mode
NOTE
○ Check that there is nothing obstructing measurement by the laser.
○ Do not move the instrument during measuring (except during
continuous measurement).
○ The center of the laser beam is measured. The same applies when
the beam is aimed diagonally at the target.
○ The measuring range may vary depending on the characteristics of
the laser beam refl ected from the target surface or the surrounding
brightness.
To measure quickly and accurately outdoors in bright sunlight, use
a target plate (sold separately) or put the target in the shade.
○ Measuring errors may occur with transparent surfaces (such as
glass or water) or mirror surfaces, as well as in the case of surfaces
with holes in, uneven surfaces, diff erent temperatures and indirectly
refl ected light.
○ If the power is turned on and no button is pressed, the power will
turn off automatically after approximately 3 minutes. Press the
power button again to resume operation.
○ If the instrument is used and then left with no button pressed,
the laser will turn off after approximately 30 seconds. Press the
measure button again to resume operation.
○ The length of time after the power is turned on until the instrument is
ready to measure may vary depending on the usage environment.
○ If an error occurs while measuring, remedy the cause before
resuming measuring.
Measuring distance (Fig. 2, 6)
1 Select distance mode. (See "Selecting a measuring mode")
2 Press the measure button and aim the laser beam at the target. The
status is indicated on the display.
3 Press the measure button again to stop measuring. A beep sounds
and the measurement is indicated on the display. When measuring
is fi nished, the laser goes off .
4 To continue measuring distance, repeat steps 2 and 3.
The side button on the side of the instrument has the same function
as the measure button on the operation panel.

For convenient operation in narrow spaces, the instrument can be
placed in a vertical position.
Continuous measurement
Use continuous measurement to set the desired position from the
target.
1 Select continuous measurement mode. (See "Selecting a
measuring mode")
2 Press the measure button and aim the laser beam at the target.
3 Move the instrument until the desired measurement is indicated on
the display.
4 Press the measure button again to fi nish continuous measurement.
The last measurement is indicated on the display.
Measurements are successively indicated on the display with a beep
sound every 0.5 to 3 seconds.
The previous measurement is deleted when the next measurement is
taken.
In continuous measurement mode, the power does not turn off
automatically. Be sure to press the power button after operation to end
continuous measurement.
Measuring area (Fig. 11)
If you measure the length and the width, the area is automatically
calculated.
1 Select area mode. (See "Selecting a measuring mode")
2 Measure the length.
○ Press the measure button and aim the laser at the target
length.
○ Press the measure button again to fi nish measuring. A beep
sounds and the length measurement is indicated on the
display. The laser does not go off at this time.
3 Measure the width.
○ Press the measure button and aim the laser at the target width.
○ Press the measure button again to fi nish measuring. A beep
sounds and the width measurement and calculated area are
indicated on the display.
