USE

●

On/off 
- switch on the tool by pressing "Power" button
- ambient temperature in °C is shown on display
- switch off the tool by pressing "Power" button again
- the tool automatically switches off after 30 seconds of

inactivity

●

Mounting of battery 

4

! ensure that the tool is switched off
- remove cover P
- insert 9V battery (pay attention to correct polarisation)
- mount cover P
- when battery level is low, symbol 

5

will appear in

display 

! change battery in time, otherwise faulty

measurements may occur

- always remove the battery from the tool, if the tool is

not used for a long period

●

Metre/feet conversion
- measurements are in metres/centimetres by default
- press button E 

3

for converting metres/centimetres

into feet/inches

- setting will not change as long as battery is not

removed from tool

●

Operating the tool 

6

- press "Power" button
- select measurement mode (button F, G, or H)
- place rear edge of the tool on the starting-point of the

measurement

! aim the tool towards the target surface at a right

angle (use bubble levels M 

3

)

- a laser "target" 

7

is projected on the target surface

as an indication of where the ultrasonic signal is
reflected by the measured object

! do not look into the laser beam
! do not point the laser beam at persons or animals
- press "Read" button; measured distance appears on

top line of display

! keep in mind that the tool measures from its rear

(the tool length is included in the measuring result)

●

Instructions for proper measurement 

6

! do not move the tool during measuring
! do not measure beyond the specified

measurement range (0,5 - 15 m)

! ensure that there are no obstructions within the

conical expanding sound range 

- large, hard and flat surfaces give the most accurate

results

- place a piece of cardboard in front of the target

surface, when measuring small, soft or irregular
surfaces (such as carpets, curtains, coarse wallpaper,
etc.)
