MEASURING PROCEDURE
VOLUME MEASUREMENT (Fig. 6)
After switching on, the measuring tool is in the length measurment
mode. Other measuring modes can be switched to by pressing the
function transfer button (2).
1. After switching on, press function button until the icon for volume
measurement appears on the display.
2. Press measuring/on button to measure the length, width and the
height, one after another in the same manner as for a length
measurement. The laser beam remains switched on between all
three measurements.
After taking the third measurement, the volume is automatically
calculated and displayed. The last individual measured value is
indicated at the middle line in the display, while the final result is
shown at the bottom.
After taking the second measurement, the area/surface is
automatically calculated and displayed. The last individual
measured value is indicated at the second line in the display, while
the final result is shown at the bottom.
With the reference point selected, place the measuring tool
against the desired measuring line (e.g. a wall), press the
measuring/on button to switch on the laser beam.
Aim the laser beam at the target surface. Press the measuring
button again to initiate the measurement.
The measured value typically appears after 0.4 seconds and at
the latest after 3 seconds. The duration of the measurement
depends on the distance, the light conditions and the reflection
properties of the target surface. The end of the measurement is
indicated by a signal tone. The laser beam is switched off
automatically upon completion of the measurement.
For measuring, you can select between three different reference
levels:
• the rear measuring-tool edge (Fig. 1, e.g. when measuring
onward from a wall)
• the middle part of body (Fig. 2, e.g. when measuring from the
middle)
• the front measuring-tool edge (Fig. 3, e.g. when measuring
onward from a table edge)
To change the reference point, press the reference point
selection button until the requested reference point is indicated
on the display. Each time after switching on the measuring tool,
the rear end of the measuring tool is preset as the reference
point.
1. Press measuring/on button to activate the laser, and aim at
the object which is to be measured.
2. Press measuring/on button again to take measurement, the
measured value is indicated at the bottom in the display.
1. After switching on, when you want to measure the total
distance after you measure the first distance, press add
button ”+” (4), then again press measuring/on button to
measure the distance you want to add, it can calculate
automatically and the result displayed.
2. After switching on, when you want to measure the short
distance, after you measure the first distance, press
subtraction button ”-” (5),then again press measuring/on
button to measure the distance you want to sub, it can
calculate automatically the result displayed.
1. After switching on, press function button (2) until the icon for
area measurement appears on the display.
2. Press measuring/on button to measure the length and the
width, one after another in the same manner as a length
measurement. The laser beam remains switched on between
both measurements.
WARNING! Do not point the laser beam at persons or
animals and do not look into the laser beam yourself, not
even from a large distance.
Always replace all batteries at the same time. Do not use
different brands or types of batteries together.
Do not leave the switched-on measuring tool unattended
and switch the measuring tool off after use.
Other persons
could be blinded by the laser beam.
Protect the measuring tool against moisture and direct
sun light.
Do not subject the measuring tool to extreme temperatures
or variations in temperature. As an example, do not leave
it in vehicles for longer periods. In case of large variations in
temperature, allow the measuring tool to adjust to the ambient
temperature before putting it into operation.
Avoid heavy impact to or falling down of the measuring
tool. After severe exterior effects to the measuring tool, it is
recommended to carry out an accuracy check each time
before continuing to work.
To switch on the measuring tool, press the measuring/on
button (1) for a few seconds.
When switching on the measuring tool, the laser beam is not
switched on yet.
To
switch off the measuring tool, press the off and memory
delete button (7) for a few seconds.
Remove the batteries/rechargeable batteries from the
measuring tool when not using it for longer periods.
When storing for longer periods, the batteries can corrode and
self-discharge.
After switching on, the rear edge of the measuring tool is preset as
the reference point for the measurement. To change the reference
point, please press the reference point selection button (6).
If none of the measuring tool buttons are pressed for approx.
3 minutes, the measuring tool switches off automatically in order to
extend the service life of the battery.
Upon selection of the measuring function and the reference point,
all further steps are carried out by pushing the measuring button.
When no measurement has taken place approx. 30 seconds
after sighting, the laser beam is switched off automatically to
save the batteries.
