2. Aim the range meter at the target.
3. Press the “Measure” button. The first distance will
be measured and displayed (the laser then switches
off).
4. Press the “Minus” button. The first distance is then
displayed in the middle result line and a minus sign
appears in the lower (intermediate) result line (the
laser beam switches on).
5. Aim the range meter at the target.
6. Press the “Measure” button.
The second distance is then measured and dis-
played in the lower (intermediate) result line.
The result of the subtraction is shown in the result
line.
The current difference in distance is always shown
in the result line.
The procedure can be repeated until all distances
have been subtracted.
7. To terminate the subtraction of distances, simply
measure a distance without first pressing the
“Minus” button.
All previous measuring and calculation results are
shown in the intermediate results lines.
8. Press the C-button to clear the display.
7.4 Timer
The timer function works like the self-timer on a camera.
The “Plus” and “Minus” buttons can be used to adjust
the timer interval to one of the three settings: 5, 10 or
20 seconds. To activate the timer, press the “Measure”
button. To stop the timer, press the C-button. A beep
sound is emitted every second up to about 4 seconds
before the timer triggers the tool. The last 4 seconds are
counted down by a double beep every second.
7.5 Measuring areas
Each step of the area measurement operation is indicated
graphically in the display. For example, to determine the
floor area of a room, proceed as follows:
1. Press the FNC-button to activate the area function.
NOTE When the area function is activated, the laser
beam is already switched on.
2. Aim the range meter at the target.
3. Press the “Measure” button.
The width of the room is measured and the value
displayed.
The graphic display automatically prompts you to
measure the length of the room.
4. Aim the tool at the next target to obtain the length
of the room.
5. Press the “Measure” button.
The second distance is then measured, the area
calculated immediately and the result is displayed
in the result line.
Both distances used for the area calculation are
shown in the intermediate result lines and can be
noted down conveniently at the end of the operation.
